How Much Do You Know About Mini Projector
The projector consists of LCD and DLP projector From the current chip
projector. As the different sizes and different imaging principle, the
size of the projectors used the two different chips are also different.
LCD projector's core component is the LCD panel. This technology used in projectors is older and more mature. With 0.5 inch LCD panels being used and improved optical design, LCD projector products have reached the weight only 1.6kg, so the portable ability has received a good development.
In contrast, DLP portable projector used DMD chip has an advantage in portable performance. Generally we consider that the projector is portable when the weight is less than 2.5kg. But the weight of the portable projector used DLP processing technology is only 1kg or less. So it usually is considered the super lightweight projector.
In general, the application of portable projectors for business is not usually used to demonstrate the complexity video or animation. But in general it is used to demonstrate the static documents, charts, for example, Word, PowerPoint documents. So portable projector can meet the business needs completely.
When the applications of mini projector are used for mobile business and training dozens of people, generally the projected area is in 60 inches or less. So, it do not need a portable high brightness product.
What should be considered when choosing and purchasing
When choosing a portable projector, the performance is the important point to compare the different product. If you want to buy a portable projector, you need to pay attention to brightness, contrast, resolution, lamp life and service.
The brightness of mini projector is generally between 800 to 2000 lumens. Users should select the size of the projector's brightness to purchase mini one according to their size requirements and the environment brightness. In general, if the demo environment area is 15 square meters and there is poorly lit, the projection brightness of 800 lumens is sufficient. If there are some light in the presentation environment, the 1000 lumens are appropriate. And if there is in the open space and strong light environment, you should consider about 2000 lumen projector. It should be noted that the current general machine used in the whole semi-dark room can also have good results. Brightness will also be different because of different projection distance. the projector farther away from the screen, the image brightness will be lower.
According to the different imaging principle, portable LCD projector may reach 400:1 contrast ratio, and the DLP portable projector can reach 1000:1 contrast ratio. Obviously DLP projector is better than LCD one in the indicator of contrast ratio, but this does not mean that we must choose DLP projector, and in fact the general document projector only need 400:1 contrast ratio. Users can try to use it and know the projection effects when choocing or purchasing.
In the market some store staff will advise you to buy the best image resolution machine, while we recommends that users according to their actual usage to select. For example, if your projector is usually used together with the notebook, it's great to select the resolution projector same as you notebook's resolution. Current portable projector is available to reach the general resolution of 800 × 600, which can meet the needs of the general projection. At the same time, we should note that the prices of general projector will increase with the resolution enhancement.

Digital Projector Rental - Choosing The Right Projector For The Job
The digital revolution is here.Digital projectors are now the staple
presentation devices used for photography shows, classroom instruction
and high-end meetings due to their ability to deliver crisp, clean and
saturated images. Such crisp, bright images displayed by digital
projectors capture and hold an audiences attention and that makes a
difference whether you're using your companies smallest meeting room or
its biggest auditorium.
According to Digital Projector Paybacks, 90 percent of business survey participants said digital lcd projectors gave them an enhanced ability to persuade during presentations. Digital projectors make large-scale presentations easy to coordinate. They can plug directly into your computer/laptop, DVD player or video camera and many come equipped with remote controls and laser pointers for ease of presenter operation. Ideal for Power point presentations, seminars, boardroom meetings and promotional events, can you afford not to utilize the presentation technology of a digital projector for your next sales pitch, conference of exhibition?
While the benefits of using digitally projected images to enhance your presentation are obvious, the purchase price of a digital projector and the high cost of replacement lamps are a barrier to many businesses, however there is an alternative, lcd digital projector rental. For a fraction of the purchase price businesses can hire all the necessary equipment to transform their presentation or promotion into a state of the art audiovisual experience.
Lcd digital projector rental provides you with the flexibility to choose the right product for the job but there are many factors to consider when making that choice including the aspect ratio, room size, screen size and color, projector throw distance and luminosity.
Digital Projector Features
Aspect ratio refers to the dimensions of the image created by the projector. Not to be confused with the size of the projected image on the screen, aspect ratio basically sets the shape of the image. There are three standard aspect ratios. For data presentations and video the standard aspect ratio is (4:3), For wide screen images such as HDTV, DVD and a growing number of satellite and web based TV broadcasters the standard aspect ratio is (16:9). The third and least used aspect ratio is (1:1), or squares. Commonly used to present overhead transparencies in a digital format, this aspect ratio has limited functionality in today's wide screen world
When considering digital projector rental screen size and color does matter. First you need to make sure your screen has the same aspect ratio as the projector otherwise your image will not fit the screen making your presentation look second rate. While most rental digital projectors have variable aspect control allowing you to manually choose the aspect ratio that best suits your imaging, converting an image which is meant to be projected in HDTV format (16:9) to another aspect ratio so it will fit on the screen, will impact on the quality of the image. Always err on the side of caution and double check with the projector rental company to ensure the model you hire has the desired aspect control format and control and comes with a screen to match. If you are going to be projecting in a dark environment choose a white screen or alternatively in a bright environment choose a black screen.
Understanding the relationship between room size, screen size, throw distance and luminosity is crucial to making the right lcd digital projector rental choice. Getting the formula wrong can have disastrous effects on the quality of your presentation.
Just remember that the size of your room determines all other factors and apply this simple formula. The minimum distance a person should be seated from the projected image to allow the human eye to focus on the whole screen should be at least two screen widths. The maximum distance a viewer should be seated from the projected image is six times the width of the screen.
Once you have worked out the screen size and color required, you would need to find a digital projector with an appropriate throw distance. Throw distance refers to the maximum allowable distance between the projector and the projector screen before engaging quality compromises. Most standard lcd digital projector rentals are adequate for office or boardroom presentations, however if you are considering a presentation in a large venue or arena you may need to look to a professional stage and lighting company The point to remember is the bigger the room the greater the throw distance required.
The final point when considering digital projector hire is luminosity. Luminosity refers to the brightness of the projected image. The higher the lumens of the projector the brighter the image. The standard modern lcd projector has a minimum lumen rating of about 1500 lumens. While this is more than adequate for an indoor environment with dimmed lighting, if you are planning on using the projector in an outdoor environment or a well-lit building such as a shopping centeryou will need a projector with at least 3000 lumens.
LCD digital projector rental is a cost effective solution to your presentation or promotional needs which greatly enhances your persuasive capabilities with clients. Don't get left behind by your competition, your presentation sells an image, so make it a good one with the support of LCD digital projector imagery.

Things to Consider When Buying a Projector
Projectors are one of the best inventions in the field of multimedia.
This new technology is able to zoom in an image and project it towards a
flat surface so that more people can view the illustration with ease.
It has greatly helped businesses in presentations, meetings and
analyses.
Uses of Projectors
One of the more useful functions of projectors is disseminating information or giving entertainment at a larger base. The latest projectors can just about do everything to make the job of educators, students, businessmen and others who need an effective method of presenting important information easier and clearer.
The use of projectors is not limited to management of information dissemination; it has also made significant contributions to making people's lives better and more comfortable. Projectors make home viewing more entertaining since viewing is always better in a larger screen. People find the idea of having a home theater particularly relaxing and convenient.
Types of Projectors
There two different types of projectors - the LCD and the DLP. LCD stands for Liquid Crystal Display while DLP stands for Digital Light Processing. LCD projectors provide vibrant colors and sharp images compared to the DLP variety because it has a higher lumens output. On the other hand, DLP projectors are handier. All projectors that weigh three pounds or less are DLP projectors.
The decision to select a DLP or a LCD depends on what activities the projector will be used for. PowePpoint presentations are better with LCD projector. The DLP projector offers the best quality output for moving images like movies or audiovisual presentations. The size and weight of the unit should also be considered. This means that if the job needs constant relocating, then the handier DLP will be the logical choice.
There are differences to the quality of output of different models because models have different specifications and capacities. Projectors with the highest Lumens can offer the brightest and clearest images.
Appropriate for trade shows, conventions and conferences are projectors with 6000 Lumens. This type of projector is understandably pricier and heavier as compared to models with lower Lumens. Most people use projectors with 2000 Lumens, an entry level projector. The best projector, naturally, will depend on the use the buyer intends to put it into.
Buying a Projector
In buying a projector there are a few things that should be considered. Each type or model of projector has its own characteristic in terms of functionality, output and price. Functionality can, of course, influence the value of the presentation. This means that the ease of use is as important as the clarity of image. Although, manufactures practically utilize the same technology, whether it's the LCD or DLP type, the controls and responsiveness differ with each product. Naturally, you will find that the simpler the controls the better.
The price is another determining factor in deciding the type and model of projector to buy. Present projectors have prices that range from $1,500 to $ 20,000. The price depends on the features, functionality, size, weight, and output quality.
The clarity of images generated by the projector is the single most important factor in choosing the type and model to buy. Projectors with higher resolutions and brightness have clearer and sharper image outputs. The resolution data as well as other useful information about the projector are usually included in the product information as provided by manufacturers. This means that it will not be too difficult to decide on the kind of model that can guarantee the best image output.

What You Should Know About Buying a Projector From eBay Or Online Auction
Many people wish to purchase a home projection theater system but still
have to work within the constraints of a budget. Can a budget projector
be a viable alternative? While a thousand dollars is still a lot of
money, it really is not so much to pay for a good home theater
projection system. A good home theater will provide years of
entertainment from movies, to video and computer games to vacation
picture slideshows. How though, can someone find a projector for less
than one thousand dollars? How can anybody find a quality projector that
also fits the category of a cheap projector? How can they make sure it
is going to suit their needs?
One of the most obvious options is through auctions. This is a very difficult way to purchase a projector. The main reason is that all you can do is asking questions of someone who has already proven that they are a motivated seller, proven by the very fact that they have posted the projector on an online auction. Bidding online can be done with some level of confidence though. It is very easy to conceive of getting a very good multimedia projector for less than a thousand dollars in this manner.
Making sure you ask the questions you want answered is the first challenge in finding a home theater projector online. While this may sound easy enough, it really is not when you think about it. For example:
Buyer: Why are you selling your projector?
Seller: Because I am thinking about buying a new projection system. (Thinking, looking, considering ... all are terms to make the buyer beware)
Why would this simple question and answer dissuade someone from actively bidding on this projector? Take a moment to look at it more closely. The seller obviously wants to sell the projection unit that they currently own. But "why do they want to sell it" is the relevant question. The answer states that they are looking, considering, thinking about, or otherwise contemplating the purchase of a new system, this is not to say that they are actively in the process of purchasing a new system. This in turn, should lead the prospective purchaser of the online auction projector to ask themselves, and the seller, a series of other questions. Why are they selling the projector without having found a new one they are sure of?
While there are literally thousands of different combinations of this simple question and answer "red flag," the key is the same in all of them. If the seller will not give specifics then buyer beware. It is better to lose a bid on a high quality projection theater system than it is to win even with a low bid for a damaged projection unit. The cost of repairs, while relevant in the long term of projector life is important; it should not have to be a factor when purchasing a new projector, no matter where it is bought.
Things to look for that will indicate it may in fact be a quality cheap projector usually are some type of upgrade on the part of the seller. While they may still be very happy with the unit they are selling, somehow or another they have managed to put together the money for a new home theater projector display and setup. Another factor may very well be that they were uninformed when they made the purchase.
One key to making a new projector purchase is making sure the store where it is purchased has a good return policy. Ambient lighting, (while the most common factor, is not the only one) will cause many projector displays that look great in the store display to function less than ideally in the purchaser's home. It may well be that the seller did not ask the right questions when they bought the projector and they cannot return it. This happens more than most people want to admit ... with any number of products, not just with projection units. Asking the correct questions can make it easier to figure out if the projector will be right for your needs or not.
Ask the seller about the picture quality of the projection unit they are selling. If the seller is specific and gives you an answer saying that it is not what they expected, there could be other mitigating factors that will make this ideal for you to get a great deal on a great projection system for well under one thousand dollars.
Find out what kind of projection screen they are using. If the projection screen is not ideally suited to the home theater projector they purchased, that could be a point in favor of the buyer. Sometimes a person will spend a great deal of money on a projector and use the blank space on the wall to project the multimedia displays. If the projector shuts off or flickers. This could be an indication that the projector is fine (For the moment) but has been set up somewhere that is either too dusty for the projection unit filters to keep up or it has been set up somewhere that there is not sufficient airflow and the projection unit is overheating. Find out specific details about where the projector is. Do not be afraid to ask questions. The worst that can happen is that they will refuse your bid and save you money. Not a bad deal really, and certainly better than ending up with a home projector that will not work at all or that needs substantive repairs.
If you know that the projector is functioning well but the picture quality is not what it should be, there could well be another frequently encountered problem. This is known as the keystone effect. Most projection units come with keystone adjustment features. The concept is to allow the optic lenses to be adjusted horizontally and vertically. While this can be a great benefit in some projectors, some home theater systems will become quickly inundated with the keystone effect. To make a long story short, the screen and the projector have pixels. The pixels are little concave shaped areas where light is projected and displayed. The keystone effect occurs when the pixels on the screen are not correctly aligned with the pixels being projected from the projection unit. This will greatly detract from the viewing pleasure and often causes unpleasant sensations such as headaches to the viewer.
If a buyer is willing (And well informed enough) to ask specific questions they should get specific answers. If the seller refuses to be specific or to discuss details, than do not bid. Ever! The well-informed buyer will never end up with a seriously damaged projector, and just may, if they ask the right questions, end up with a high quality home theater projection system for well under a thousand dollars.

Choosing the Right Projector Mount for Your Video Projector
Ok, so you've bought your new projector and you're excited to start
watching movies, but did you remember to also buy some sort of projector
mount? Projector mounts are one of the most overlooked accessories
needed to use your projector effectively. Sure propping it up on the
table with some books works for now, but a more permanent mounting
system needs to be considered for the long term.
When considering projector mounts you have 3 main options available to you. In order of preference they are; ceiling mount, table top mount and wall mount. This article will talk about these different mounting options and the specifics of each. Also if you plan on using a one of the various ceiling projector mounts then make sure first that your projector has a ceiling mode on it that will flip the picture around and display it correctly.
There are also high tech projector mounts that will mount your projector flush and hidden in your ceiling or wall and then will extend itself on a motorized track when you want to watch a movie or use the projector. And then when you are finished the projector will retract back in the ceiling or wall. This is not a cheap option, but it is very cool and if your budget can afford it, then why not go for it.
Available Projector Mounts:
Ceiling Mounted Projector
A ceiling mount is by far the most popular of the available projector mounts. A few of the things you need to take into consideration when looking at ceiling installation are; the weight of the projector, projector size, will ceiling fans or hanging light fixtures be in the way, will it take away from your homes décor?
Tabletop Mounted Projector
As far as projector mounts go a table top mount is certainly the easiest to install, however there are a number of things to consider. Is the projector in a high traffic area where it can easily become damaged? Can the projector adjust to allow the picture to display properly on the screen? Will the noise from the projector running interfere with your movie? Do you have kids who could burn themselves on a hot projector?
Wall Mounted Projector
Projector mounts in a wall setting are typically mounted in a corner of the room up near the ceiling and above average head height. Some things to consider about wall mounts are: Does the projector have an unobstructed view of the screen? Is the projector mounted high enough so as not to be a hazard for people's heads? Can your wall mount handle the weight of your chosen projector?
Use the above information to help you decide which of the available projector mounts is right for your home or office.

When considering projector mounts you have 3 main options available to you. In order of preference they are; ceiling mount, table top mount and wall mount. This article will talk about these different mounting options and the specifics of each. Also if you plan on using a one of the various ceiling projector mounts then make sure first that your projector has a ceiling mode on it that will flip the picture around and display it correctly.
There are also high tech projector mounts that will mount your projector flush and hidden in your ceiling or wall and then will extend itself on a motorized track when you want to watch a movie or use the projector. And then when you are finished the projector will retract back in the ceiling or wall. This is not a cheap option, but it is very cool and if your budget can afford it, then why not go for it.
Available Projector Mounts:
Ceiling Mounted Projector
A ceiling mount is by far the most popular of the available projector mounts. A few of the things you need to take into consideration when looking at ceiling installation are; the weight of the projector, projector size, will ceiling fans or hanging light fixtures be in the way, will it take away from your homes décor?
Tabletop Mounted Projector
As far as projector mounts go a table top mount is certainly the easiest to install, however there are a number of things to consider. Is the projector in a high traffic area where it can easily become damaged? Can the projector adjust to allow the picture to display properly on the screen? Will the noise from the projector running interfere with your movie? Do you have kids who could burn themselves on a hot projector?
Wall Mounted Projector
Projector mounts in a wall setting are typically mounted in a corner of the room up near the ceiling and above average head height. Some things to consider about wall mounts are: Does the projector have an unobstructed view of the screen? Is the projector mounted high enough so as not to be a hazard for people's heads? Can your wall mount handle the weight of your chosen projector?

Digital Projectors - Key Features To Look For When Buying A New Projector
A digital projector is a device that connects to a computer or like
devise via cabling to enable the computer monitor display to be enlarged
and projected onto a screen. The standard digital projector connects
via a VGA lead direct to your computer or uses component video cables,
(red, green and blue plugs) to connect to your DVD player, HDTV, set top
box or video camera. However to be safe always make sure to double
check the projector has the right outputs to connect to the devise or
devises you wish to connect it to. Features of a quality digital
projector should include:
Digital Projectors - Resolution
Digital projector resolution refers to the pixel density of the image to be projected. A digital projector has two resolutions, the natural resolution and maximum resolution. The natural resolution is the standard pixel size of the projected image; the maximum resolution is the maximum capability of the projector. Typically a digital projector should be able to accept resolutions of 800x600, 1024x768 or 1280x1024, however it is not the size of the resolution the digital projector can accept which is important, but rather the native resolution of the projector. The higher the native resolution of the projector the greater the colour quality, or should I say color density of the projected image.
Digital Projectors - Lumens
Lumens refer to the brightness of the projected image. Simply put the higher the lumens the brighter the projection. Brightness ratings, measured in lumens, are typically lower for home theatre models than for office models. Room size and screen size/distance will also affect the need for more or less lumens. A projector may have a great Lumens rating, but if the contrast ratio is low, you image will look washed out. For low-ambient or true lights-out productions, you may find that a 1000 to 1500 lumens rating is sufficient. If you need a very bright projector (3000 lumens or more), an LCD projector is probably your best choice. The lowest lumen projectors today start at about 700 lumens and go up to a jaw-dropping 15,000 lumens. A good rule of thumb is that it is always better to err on the side of too many lumens than too few.
Digital Projectors - Throw Distance
Throw distance refers to the maximum distance your digital projector can be positioned away from the screen before image resolution, luminosity and therefore image quality are affected. The greater the throw distance, the larger the size of the projected image on the screen. Digital projector throw distance is an important key feature if you are planning to use the projector in a large room or outdoor environment, however for the home user today's basic digital projector has more than sufficient throw distance to meet the needs of your home movie theatre.
Digital Projectors - Aspect Ratio
Aspect ratio refers to the ratio between the width and height of the projected image. There are three standard aspect ratios settings that you should ensure your digital projector projects these are: 1:1, 4:3 and 16:9. Having a digital projector which has aspect ratio options are important as different media are delivered in different aspect ratios. For example standard video is delivered with an aspect ratio of (4:3), while HDTV uses a (16:9) format. If your digital projector had a locked aspect ratio of (4:3) you would not be able to experience in full, the visual experience of wide screen movies or images. With more and more digital media including cable and online TV networks adopting the (16:9) format this is something to definitely check.
Display Features - fixed keystone correction and lens shift functions
To ensure you can maximize the quality of the digitally projected image on your presentation screen ensure that the digital projector has fixed keystone correction and a lens shift function. Fixed keystone correction shoots the image higher than the lens so the projector itself doesn't block the viewers line of sight. Similarly the lens shift function allows you to shift the image up and down and left and right. A handy tool for making fine-tuning the position of your projected image on the screen.
If you are considering buying a digital projector remember the key features to look for are high native resolution, high luminosity and a suitable throw distance for the environment you intend to use the projector in.

Should Businesses Buy a Projector Or an LCD Display?
With the price of large (>32") LCD displays decreasing rapidly and
new functionalities being added to LCD displays, does it still make
sense for businesses to buy a projector vs. an LCD display?
Some of the variables to consider when evaluating this question are product quality, price, picture quality, screen size and other such considerations. We discuss these and other factors from a typical business organization perspective. Read other articles and make your informed judgement.
Product Life: LCD TVs or displays typically have a backlight life of 30,000 to 60,000 hours (ie, if you have the display on for ~6 hours every day, the backlight will last for 16 years). Even then the backlight can be replaced in most LCD displays. A projector bulb typically has a life of 2,000 hours.
Price Considerations: A basic projector can be found for INR 25,000. However, if the projector is going to be used for video conferencing or board room presentation, a high resolution, good contrast ratio and saturated colour projector would be required. The cost of such a projector is close to INR 1 lakh. Thereafter, you need to factor in the prices of projector bulb and projection screens. A typical projector bulb needs to be replaced almost every year or two with bulbs costing Rs 20,000+ per bulb. We have added these costs over a five-year period to compare a projector vs. an LCD (see chart below). With 46" LCD TV or display costing around Rs 135,000 - Rs 150,000 and dropping, price becomes less of an issue when considering whether to buy a Projector or LCD display
Figure: Total Cost of Ownership Comparison for Projector vs. LCD Display
Basic Device capital cost for projector is INR 70,000 and that of an LCD display is INR 150,000, Projector Screen Capital Cost (Wall Mount Screens INR 5-15K) is INR 10,000, Consumable cost of the projector is 20,000 x 3 = INR 60,000, Consumable life of a projector is 2,000hrs and that of an LCD display is 60,000hrs and the Cost of Ownership of a projector is Rs.140, 000/- and Rs.150, 000/- for an LCD display.
Assume: 5years of usage @ 5hrs a day ~ 6600hrs of use. This translates to 4 lamps in 5 years requiring the customer to buy 3 lamps in addition to 1 supplied with machine.
What is clear from the above figure is that a Full High Definition 46" LCD Display is, at best, only marginally costlier than a XGA Projector of ~2500AL. Additional costs of low screen installation costs and lower device loss costs are purely additional.
Picture Quality: Projectors such as a DLP or LCD projector use glass panels to combine red, green and blue colours to create the image. When sitting close to screen, the viewer can see the different colours at the borders of an image, aptly described as the rainbow effect. The rainbow effect takes away from the image quality and can give headaches. High-end projectors have been able to reduce the rainbow effect, however the problem still remains and these high-end projectors cost more. LCD TV or LCD displays do not have rainbow effect issues and the quality of the picture is good at close range.
Rather, projectors cannot compare with the picture quality for an LCD display. The vividness of the colours, the contrast ratio, the colour saturation and image sharpness are much better for an LCD display than a projector. When viewing a projector image, especially in ambient light, the viewer has to dim the lights or close the curtains unless the business has purchased an even more costly higher lumen projector. Not true with LCD displays, as the brightness and colour quality are much better.
Viewing angles used to be an issue with LCD displays but this issue is no longer true. Most LCD displays can be viewed from up to 176 degrees.
Dead or Stuck Pixels Projectors can suffer from dead pixels and LCD displays can suffer from stuck pixels. Both dead pixels and stuck pixels result in white spots in the projected image. However, the manufacturers of both technologies have worked hard to minimize such issues and in most cases they provide warranty against such issues.
Screen Size: A common thought is that screen size is not an issue for most projectors as the thinking is that the projector image can be made larger by moving the projector away from the screen. This is not true as the image quality deteriorates as the image becomes larger. With projectors, most buyers opt for maximum optimized projector image sizes from 76-inches to 120-inches and the actual working normal projection image used is much smaller. Today, if businesses need a large LCD display in the maximum projector image size, a wide variety of competitive LCD displays can be found in this range.
Portability: Projectors are easy to carry and move around. For a business this could be a value-add or a drawback. LCD displays are durable and can be moved however they are not as light as projectors.
Power Consumption: Projector power consumption varies more from unit to unit, with brighter conference projectors requiring more power than smaller portable projectors. It is hard to compare the two technologies on this performance parameter.
Connectivity: Most LCD displays have more number and different types of ports than projectors. As a result more types of devices can be connected to an LCD display than a projector.
Other Value-Add Features: New features are appearing in LCD displays that could be quite valuable for businesses. For example, touch screen features on LCD displays allow for LCD displays to be used as digital whiteboards where the data written on the display can easily get captured electronically in a text document.

Brightness is being more important for the commercial use as it is being needed for presentation and conference. But the medium level of light is seen to be perfect for home cinema projector.
Good Contrast:
Contrast level with do not affect more in business as well as for the home cinema projector. In reality contrast level above 400:1 can be easily viewed by eyes. And this contrast ratio is being available in all projectors. It is used when the some picture is not seen clearly.
Colour performance:
This attribute is required when projector is used for home cinema projector. This feature is most required when required when projector is used for fast running movies, videos etc. But for the commercial level it is not more required as most use of projector for conference and presentations only.
Portability:
If you are purchasing projector for commercial use then the projector with less weight and small size will be really helpful for business use. Good portability is required if you are traveling frequently. Some of the projector has inbuilt speakers and many more good features which will be the most helpful to professional. But due these advanced features there price also increases.
But for home cinema projector this feature is of no use. Generally home cinema projector is place at fixed place, normally on ceilings.
Video projector connectivity:
Home cinema projector or the business projector is connected with pc, DVD, set top box etc. But not all projector give connectivity to s-videos, RGB connectivity features. So the good video connectivity should be checked. There are different set of standard for the Video projector connectivity.
There are different standard are kept for video connectivity such as M1, DVI, P&D give different feature of connectivity.
Some Precaution for long life of projector:
1. First durst out your room where you want to keep your projector. As the dust and the projector cannot live together. It is necessary for the long life of your projector.
2. Also use mindful for the turning off and on the projector does not give stress by often switching on and off of the projector. It will decrease life of projector.
3. Keep your eyes on projector lamp when the bulb is on. See that the bulb not be overheated. If the bulb has been overheated there is chance of burning out quickly.
4. Projector should be used in the dark room as the projector picture cannot be seen properly where there is light reflected near projector screen.
* It is our advice to check perfectly before purchasing the projector.

Purchasing a Digital Projector - How to Find the Right Product and Best Pricing
So, you have decided it is time to invest in a digital projector. All
too often, when people get excited about purchasing equipment, they skip
the most important step--research. Before venturing out or searching
online to select your shiny new digital video projector, it is important
to ask yourself some key questions about how you plan to use it. Then
you must take a closer look at the company that is selling the projector
to ensure that you get the right product and the best pricing for your
application.
Step 1 - Determine your Needs
Before you begin calling around to find the best deal on a digital projector you need to ask yourself some specific questions that will help to determine the best projector for your needs.
What is your budget? First, it is important that you have a price range in mind that you are willing to spend on a video projector. Are you looking to spend $1500 or less, or are you interested in top of the line projectors in the $3500 range, or even more? If your budget is open and flexible, you will obviously have a larger selection of products to consider. If you have a limited budget, your options will be less expansive, but you can still find a projector that will fit your needs.
Where will you be using your digital projector? The environment where the projector will be used will impact the type of product you should purchase. Will it be used in a company training room or conference room? Or, will it be used in a large auditorium or smaller school classroom. Considering the size of the room where the projector will be used is an important factor when deciding which digital projector you should purchase.
How often will you be traveling with your projector? Keep in mind how often, if at all, you will need to take a video projector with you to other locations. If you will be taking it with you to sales meetings in other states, a digital projector that is more compact and lightweight is the best projector to buy. If the projector will remain stationary, or only needs to be moved short distances, the size and weight of the product will not be important factors to consider. If you are looking at permanently mounting the projector then you will need to consider a ceiling mount and also longer cables for the installation.
How large is your typical audience? The average size of audience will effect how bright of a computer/video projector you should choose. Will the projector be used in an auditorium that holds 200 people? Or, will it be used in a classroom of 25 students? Is this something that will be put in your home theater where there are only a handful of people and the brightness of the room is controlled. The quality of projected images varies from product to product, and there are projectors that are made specifically for all size ranges of audiences and all different lighting situations.
What types of images will you be projecting? To ensure that you choose the best projector for your application needs, consider what types of image you will be projecting. Depending on whether you plan to use a digital projector to show CAD/CAM drawings, photo quality graphics, computer images, basic video, or High Definition video there is a projector available that is formatted for your specific needs.
Step 2 - Choose a Quality Projector Supplier
Once you have answered the questions that will help determine what type of video projector you need, it is time to consult an expert who has the product knowledge to provide you with the right projector at the best price. Knowing your vendor is an important step to ensuring that you purchase the product that fits your needs.
Many people go online and think they can find a digital projector by searching product catalogs or comparing deals on different websites. The best thing you can do to ensure that you get the lowest price without compromising the quality of the digital projector is to talk to an expert. Technology changes all the time and there is always something new on the market. A quality digital video projector supplier will make sure that you are up to speed on the best products available now in the price range where you are looking to purchase.
It is important that you speak to a digital video projector supplier that is respected and known for providing quality products at reasonable prices. Confirm that the company is manufacturer-authorized so that you know you can expect thorough support from experts who are trained by the projector manufacturers. If you choose a supplier that is not manufacturer-authorized, there is a chance that the company is selling used or remanufactured equipment. Buying used equipment may seem like a good deal because of the lower price, but you will be thankful you purchased a new digital projector with a factory warranty and quality support if you should ever have issues with the product.
Conclusion
Before you invest in a digital video projector it is important that you have a clear understanding of how you will use it. Asking yourself questions to determine the needs for your particular application is an important step to finding the best projector for you. After you determine your specific needs, you should consult with a manufacturer-authorized computer/video projector supplier who has a reputation for both quality products and service. Following these simple guidelines will help to ensure that you find the right digital projector at the best price.

Choose the Correct Home Theater Projector
How to Pick the Correct Projector for Your Home Theater
You're finally making the jump to the holy grail of home theater video displays; the front projection system. There's nothing else that delivers that really big, impressive video image like a front projection system. It's how you get that real cinema experience in your home theater. Home theater projector prices have plummeted in recent years, and the size of the units have shrunk right along with the prices. No more do have to live with a coffin sized box on your ceiling. As sizes have decreased, the image quality and brightness have actually improved dramatically. You'll notice image quality and brightness are two separate issues.
How do choose the correct home theater projector for your application from the myriad of projectors on the market today? There are so many different units, each with their strengths and weaknesses. First of all, there are two main projection technology categories, analog and digital. Analog projectors are based on CRTs, a mature technology that's been around for decades. Those are the projectors with the separate red, green and blue picture tubes and three lenses on the front. The other projectors use one of the newer digital technologies. These projectors have a single lens on the front. There are three major types of digital projectors on the market today; LCD (Liquid Crystal Display), DLP (Digital Light Processing) and LCOS (Liquid Crystal On Silicon). Each type of digital projector has it's advantages too.
You need to evaluate your specific requirements in order to make the proper decision. First of all, look at the room. Is it a dedicated home theater or a multi use room? Do you have complete control of the light? What aesthetic concerns are you dealing with? What is your projector budget? How large of an image do you want? Do you watch primarily DVD movies, TV movies, sports, or other TV programming? What specific source components will you be using with your projector now or in the future? Is picture quality the most important thing, or are other concerns, such as noise, size or brightness more important? Are you installing the projector yourself, or are you hiring a custom installer to do the installation for you? Where must the projector be placed? Can you get the required video and control cables to that location? These questions must be answered to ensure you get the proper projector for your home theater. If you are using a custom installer, they will take into account these factors and specify the appropriate unit for you.
Dramatic improvements in the picture quality of digital projectors notwithstanding, CRT projectors still deliver the most film like image. They have no pixel structure and deliver rich, deep blacks. Properly set up and calibrated, with a good video processor, and with the proper size screen, a CRT projector will deliver simply stunning picture quality. You'll need to use a good quality projection screen, typically with 1.3 - 2.5 gain depending upon the size, viewing angel and ambient light in the room. Prices on really great CRT projectors have fallen like a rock in the last year or two. You can get a 9" CRT projector that used to cost $35,000 to $50,000, for less than a third of that figure now. Many firms no longer make CRT projectors due to the decreased demand for projectors using this technology. In addition, the required video processors have decreased dramatically as well. Ten years ago a great video processor used to cost $10,000 to $20,000. Now you can get one for well under $5,000 and as little as $2,000, brand new. They also easily last 8,000 - 10,000 hours when properly set up.
If they are so fantastic, why doesn't everybody still use CRT projectors? Well, there are many detriments to a CRT projector as well. The best ones, with the 9" tubes, are simply huge. It's like hanging an upside down bathtub on your ceiling. If you want to put one under a coffee table, it'll be one large table. They are also very heavy, around 150 - 200lbs, so you need the proper structure to support them. CRT projectors also require precise placement. They must be perfectly square with the screen, at the correct elevation for good picture quality. In addition, while many digital projectors have zoom lenses, allowing the projector to be placed at a range of distance from the screen, CRT projectors must be at a very precise distance for a specific screen size. These factors severely limit placement options. While the larger CRT projectors put out more light than their smaller counterparts, they have pretty dim images compared to even the least expensive digital projectors. Finally, CRT projectors require specialized setup in order to get a watchable, much less an optimum image. Every 6 months to a year, they must be re-calibrated to ensure you are still getting optimum picture quality.
There are some very good reasons why most people are using digital projectors in their home theaters today. Many are small and light, require minimal setup and calibration (compared to a CRT), are quiet and have a bright, sharp image. But, there are many different digital projectors, ranging in price from around $700.00 to over $100,000.00. Which one is the best for your specific application? Thankfully, the situation is changing, but many of the digital projectors marketed for home theater use are really just re-badged presentation units. Presentation projectors sacrifice good video quality for brightness. Brightness is much more important when giving a Powerpoint presentation in a lit room than the correct color palate or the black level. The red on the pie chart looks great, no matter what, as long as you can see it from the back row.
You want to choose one of the newer units that has been truly designed for home theater applications. The actual technology used for the imaging chip is not all that important, there are great examples using all three of the digital technologies. Companies such as Sony, Runco, InFocus, Vidikron, Marantz, Benq, Panasonic, Sharp, Optima and Sanyo and some others all make great home theater projectors. The projector will have great black levels, to accurately reproduce detail in the darker areas of the picture and give great contrast. Absolute brightness is not extremely important, unless you have a multi-use room without complete light control or you have a lot of people over for sporting events. If you are entertaining many people for sports, it's nice to have some light on in the room, so a brighter projector is advantageous.
Projectors come in a number of different resolutions. The lower the resolution, the smaller the screen you can use before you can see pixel structure. Also, the lower resolutions will not support true HDTV. Most will display HD, but at a decreased resolution. The lowest end projectors typically have resolutions of 800 x 600. The Texas Instruments Matterhorn chip is popular on budget priced wide screen projectors, and has a resolution of 1024 x 576. Anything over a resolution of 720 will allow for true HDTV. The TI series of HD-2 DLP chips has a resolution of 1280 x 720. In April of 2005, TI announced new DLP chips with 1920 x 1080 was ready for production, allowing for true 1080p resolutions. Projectors with this chip will begin shipping in Q1 of 2006. Blu-Ray Disc has stated they will support 1080p, so by late 2006 there will be commercially available 1080p content besides Microsoft's WMHD discs.
Another very important aspect of home theater projectors is the internal video processing. This is one of the primary differences between good home theater projectors and presentation projectors. Digital projectors must display progressive scan images at the native resolution of the chip, so any interlaced signal, such as 1080i HDTV, must be de-interlaced and then scaled to the native chip resolution. Poor quality video processors, weather in the projector or external units, cause all sorts of video artifacts that can get in the way of a satisfying video presentation. This subject alone is too in depth for this article, as entire texts have been written on the subject. However, one common video artifact is "jaggies" where diagonal lines are jagged instead of straight. Another annoying artifact caused by poor video processing is moire'. This is a pattern seen as alternating light and dark lines that change position as the image moves.
You'll want to be sure your projector supports the HDMI or DVI with HDCP copy protection to allow you to connect a HD-DVD, scaling DVD player or Blu-Ray Disc player. These devices will only allow maximum resolution on a display that has a digital video input with HDCP copy protection. In the future, cable TV and satellite providers may restrict the maximum resolution to their digital outputs too.
When choosing your new home theater projector, make sure it has the video quality, brightness, size, auditory and budget characteristics that you need. Projectors are a large investment, choose carefully and you will be rewarded with years of thrilling video in your home theater.

Prices on really great CRT projectors have fallen like a rock in the last year or two. You can get a 9" CRT projector that used to cost $35,000 to $50,000, for less than a third of that figure now. Many firms no longer make CRT projectors due to the decreased demand for projectors using this technology. In addition, the required video processors have decreased dramatically as well. Ten years ago a great video processor used to cost $10,000 to $20,000. Now you can get one for well under $5,000 and as little as $2,000, brand new. They also easily last 8,000 - 10,000 hours when properly set up.
If they are so fantastic, why doesn't everybody still use CRT projectors? Well, there are many detriments to a CRT projector as well. The best ones, with the 9" tubes, are simply huge. It's like hanging an upside down bathtub on your ceiling. If you want to put one under a coffee table, it'll be one large table. They are also very heavy, around 150 - 200lbs, so you need the proper structure to support them. CRT projectors also require precise placement. They must be perfectly square with the screen, at the correct elevation for good picture quality. In addition, while many digital projectors have zoom lenses, allowing the projector to be placed at a range of distance from the screen, CRT projectors must be at a very precise distance for a specific screen size. These factors severely limit placement options. While the larger CRT projectors put out more light than their smaller counterparts, they have pretty dim images compared to even the least expensive digital projectors. Finally, CRT projectors require specialized setup in order to get a watchable, much less an optimum image. Every 6 months to a year, they must be re-calibrated to ensure you are still getting optimum picture quality.
There are some very good reasons why most people are using digital projectors in their home theaters today. Many are small and light, require minimal setup and calibration (compared to a CRT), are quiet and have a bright, sharp image. But, there are many different digital projectors, ranging in price from around $700.00 to over $100,000.00. Which one is the best for your specific application? Thankfully, the situation is changing, but many of the digital projectors marketed for home theater use are really just re-badged presentation units. Presentation projectors sacrifice good video quality for brightness. Brightness is much more important when giving a Powerpoint presentation in a lit room than the correct color palate or the black level. The red on the pie chart looks great, no matter what, as long as you can see it from the back row.
You want to choose one of the newer units that has been truly designed for home theater applications. The actual technology used for the imaging chip is not all that important, there are great examples using all three of the digital technologies. Companies such as Sony, Runco, InFocus, Vidikron, Marantz, Benq, Panasonic, Sharp, Optima and Sanyo and some others all make great home theater projectors. The projector will have great black levels, to accurately reproduce detail in the darker areas of the picture and give great contrast. Absolute brightness is not extremely important, unless you have a multi-use room without complete light control or you have a lot of people over for sporting events. If you are entertaining many people for sports, it's nice to have some light on in the room, so a brighter projector is advantageous.
Projectors come in a number of different resolutions. The lower the resolution, the smaller the screen you can use before you can see pixel structure. Also, the lower resolutions will not support true HDTV. Most will display HD, but at a decreased resolution. The lowest end projectors typically have resolutions of 800 x 600. The Texas Instruments Matterhorn chip is popular on budget priced wide screen projectors, and has a resolution of 1024 x 576. Anything over a resolution of 720 will allow for true HDTV. The TI series of HD-2 DLP chips has a resolution of 1280 x 720. In April of 2005, TI announced new DLP chips with 1920 x 1080 was ready for production, allowing for true 1080p resolutions. Projectors with this chip will begin shipping in Q1 of 2006. Blu-Ray Disc has stated they will support 1080p, so by late 2006 there will be commercially available 1080p content besides Microsoft's WMHD discs.
Another very important aspect of home theater projectors is the internal video processing. This is one of the primary differences between good home theater projectors and presentation projectors. Digital projectors must display progressive scan images at the native resolution of the chip, so any interlaced signal, such as 1080i HDTV, must be de-interlaced and then scaled to the native chip resolution. Poor quality video processors, weather in the projector or external units, cause all sorts of video artifacts that can get in the way of a satisfying video presentation. This subject alone is too in depth for this article, as entire texts have been written on the subject. However, one common video artifact is "jaggies" where diagonal lines are jagged instead of straight. Another annoying artifact caused by poor video processing is moire'. This is a pattern seen as alternating light and dark lines that change position as the image moves.
You'll want to be sure your projector supports the HDMI or DVI with HDCP copy protection to allow you to connect a HD-DVD, scaling DVD player or Blu-Ray Disc player. These devices will only allow maximum resolution on a display that has a digital video input with HDCP copy protection. In the future, cable TV and satellite providers may restrict the maximum resolution to their digital outputs too.
When choosing your new home theater projector, make sure it has the video quality, brightness, size, auditory and budget characteristics that you need. Projectors are a large investment, choose carefully and you will be rewarded with years of thrilling video in your home theater.
