There are many reasons for people buying digital projectors,one of the
main is for the cost per image area. The benefits to buying a projector
is the vast image size, however the are some limitations which effect
the quality of image. The main things to compare are the resolution,
brightness, and contrast ratio. There are many different types of
projectors available and finding the best one to suit you is not always
easy.
* The different types of projectors include:
* Home Theatre/ Cinema Projectors
* LCD (Liquid Crystal Display) Projectors
* Digital Projectors
* Conference Room Projectors
* Portable Multimedia Projectors
Home
Theater/Cinema Projectors provide home entertainment,they can be used
for many purposes, including playing movies, DVDs, music, video games as
well as much more. They usually use DLP (Digital Light Processing) to
create a smooth high video performance, with little pixelation and high
contrast ratios.
LCD Projectors provide clearer, sharper images
than most of their counterparts, they create images by shining light
through three small LCD panels which are very vibrant and sharp in
colour. LCD projectors can be used to for movies at home as well as for
presentations. Ideally they need to be used in dimly light rooms to
produce quality images.
Digital Projectors allow the user to use
video files on their PC and makes internet viewing very effective. There
are two types of projectors to choose from, DLP and LCD. When buying
digital projectors one important factor to look for is the amount of
lumens. This is the quantityof different aspects of light that are
available at one time.
Conference Room Projectors are mainly used
to give presentations and reports in conference rooms mostly. They are
used where high resolution graphics are necessary. Ideal for medical
presentations or with high detailed artwork.
Portable Multimedia
Projectors are very light for ease of portability. These types of
projectors are able to produce noise-free presentations with fairly
accurate images.
When buying digital projectors the main keypoints to focus on are:
-Resolution-
refers to the pixel density of the projected images, Projectors have
two resolutions, the natural resolution and the maximum resolution. The
natural resolution is the standard pixel size of the image. The maximum
resolution is the maximum capability of the projector. Digital
projectors should be able to accept resolutions of 800×600, 1024×768 or
1280×1024, however it is the natural resolution of the projector that is
important. The higher the natural resolution of the projector the
greater the colour density image.
-Lumens- refer to the
brightness of the image. Simply put the higher the lumens the brighter
the projection. They are usually lower for home theatre models than for
office models. Screen size will affect how many lumens will be needed.
If the contrast ratio is low however, your image will look washed out.
Lumens typically range from less than a 1000- least expensive but low
light output, needs to be used in a dark or dimlylight room. To 3000+
extremely bright and expensive. Anywhere between 1000-2000 would be
sufficient for most tasks.
-Throw Distance- refers to the maximum
amount of distance your projector can project. Most digital projectors
will have a ample throw distance for most home and conference use. To
find out what this is go to the projectors manufacturers website.
-Contrast
Ratio- refers to the difference between the white level (light) and
black level (dark). Digital projectors with the higher ratios will have
the most well-defined pictures.
-Lamp Life- the average lamp life for digital projectors is between 1500 and 3000 hours.
Other things to consider when buying digital projectors is price, design,weight and any other extra features.
Some of the most popular brands include Sony, Panasonic, Sharp, Sanyo, Epson as well as many others.

The Right Projector Screen Can Save You Money!
At the LCD Projector Center we concentrate very much on LCD projectors,
so why am I writing about projector screens? Quite simple really. Buying
your lcd projector in isolation from the screen without considering how
they work together is likely to cost you more and give you less than
perfect results.
How can picking the right projector screen save you money?
One of the biggest challenges when choosing an lcd projector is getting the right brightness for the room you are going to be using it in. For home use you can usually darken the room. This means you can buy a cheap lcd projector, often saving many hundreds, if not thousands, of dollars.
But often darkening the room significantly is neither possible nor desirable. Buying a higher specification projector will give you a brighter image, but it's probably cheaper to buy a high gain projector screen. The quality lcd projector may cost you a thousand dollars more than a dimmer model, whilst quality projector screens that enhance the image brightness and clarity are only a few hundred dollars more.
Projector Brightness and Screen Gain
The brightness of an lcd projector is given in ansi lumens. Typical values for home theater and business presentation use are 500 to 3000. The higher the number, the brighter the picture will be. At the low end a darkened room is essential, whilst at the very top end acceptable results are possible with higher light levels. The current generation of home use projectors are typically in the 1000-1500 range.
The gain of a projector screen is the increase in brightness of the image produced compared to a flat matt white screen. This is given as a simple number, eg 1, 1.5, 2 etc. A gain of 1 means the image is the same brightness as on a flat matt white surface, whereas 2 means the image is twice as bright.
As an example, if you decide you need about 1500 lumen to get an acceptable quality picture, you could buy a projector with that rating and worry about the screen later. Or you could buy a cheaper 1000 lumen model and match it to a projector screen with a gain of 1.5. This would give you an effective image brightness of 1500 lumen at a reduced cost.
Very High Gain Projector Screens
Typical cheap projector screens have gains of between 1 and 1.2. Gains of 1.5 to 1.8 are achieved with high quality perlescent finishes at about double the cost. If money is no object and you need the maximum gain possible then you need a chromatically matched projector screen.
Gains of up to 4 can now be achieved with matched projectors and screens. An lcd projector only transmits 3 narrow wavelengths of light in Red, Green and Blue. A matched projector screen is covered with material that reflects only these wavelengths. Almost all of the ambient light is absorbed or scattered, so the projected image appears very much brighter.
The Downside of High Projector Screen Gain
Whilst projector screen gain might help you use a cheap lcd projector in brighter rooms than it could cope with on its own, there are 3 trade-offs. These are the viewing angle, color shifting and uneven brightness.
High gain projector screens limit the viewing angle. For a screen with a gain of 1 the picture appears high quality out to about 50 degrees from the projector. But at a gain of 1.5 that viewing angle is reduced to about 35 degrees. Over 2 and the viewing angle is down to around 25 degrees, making it much more difficult to layout your room.
Color shifting happens due to the surface properties of the higher gain screens. A true white screen will render colors accurately. By trying to manipulate the way light reflects, a high gain screen can cause a shift in some of the colors. This is rarely a reason not to buy, unless you really do need the colors to be spot on.
The biggest impact a high gain projector screen has on image quality is the change is brightness from the center of the screen to the edge. There can be up to 30% difference at gains over 2. This is usually not too much of a problem, but it does become far more noticeable the higher the viewing angle.
Conclusion
A little research and a bit of leg work could help you make great savings. Treat the projector screen as an integral part of your system and buy it together with your projector. Visit stores and insist on demonstrations with a variety of lcd projector and screen combinations.
Choosing a good quality, moderate gain (1.4-1.6) projector screen can decrease the cost and increase the performance of your system. A cheap lcd projector can produce a bright, clear image at higher than expected light levels. So whilst your projector screen may cost more, overall you save.
