Picking the right resolution Here are some basic guidelines for choosing the right resolution: Pick a resolution that is adequate for your presentation. If you use mostly type presentations, you can save money by going with a lower (SVGA) resolution. If you are, however, presenting information with a lot of numeric data, you may want an XGA resolution. And for highly detailed and technical presentations, such as engineering drawings, you may need the higher resolution SXGA projector. Get a projector projectorsbuyersguide that matches the native resolution of your computer. If you have a computer with SVGA resolution, then an SVGA projector will give the sharpest and cleanest image. Most of the projectors today can project input signals other than their native resolution, however, there may be a loss of sharpness and detail in the process. If you have a high resolution computer and a matching projectorsbuyersguide resolution projector is out of your price range, choose a projector that is one step down in resolution. Projectors convert a different projectorsbuyersguide input format to its native output format through a process called "scaling". Some projector are very good at scaling, thus making the fuzziness in the image very minor. The quality of scaling varies among different projectors.

The projector''s case comes with plenty of room for cables and accessories. The full-function remote control is easy to use and includes a laser pointer. You can also use a bundled utility to configure and control the projector from your PC''s keyboard. You can also download presentations to acard and then play back the presentation without a computer. Setup is fairly easy, thanks to a manual zoom lens. The autosync feature set the image size and position correctly, but substantial tweaking was required to adjust the timing. The projector did a good job at both the light and dark ends of the gray scale. has packaged up a great product with the delivering all the key elements that the frequent presenter would want at a price in the low $2,000s. It delivers excellent contrast and sharpness, and it is the brightest of the machines in the review rated 1000 ANSI lumens. The remote is without a doubt the best compact, credit-card sized remote we''ve seen. Fan noise is low. The CS4 is the smallest and lightest of the SVGAs on our projectorsbuyersguide recommended list, weighing 5.3 lbs.

Lamp life is commonly discussed in terms of " Half Life". This simply means the projectorsbuyersguide manufacture has set a limit on what they feel is the quality life of the lamp. If the lamp half life is 2000 hours, the lamp will generally last much longer although the brightness of the image may deteriorate. For example, on an LCD projector, the lamp half life is generally 2000 hours. The image brightness is normally above 85% of the original brightness up to 2000 hours. After 2000 hours you may see a drastic reduction in brightness. DLP projectors normally have less of a life and the brightness generally starts deteriorating before the half life. DLP & LCD Digital Light Processing (DLP): The commercial name for this technology from Texas Instruments (TI): The technology inside is often referred to as either "micro-mirrors", or DMD: It works this way: build a few hundred thousand tiny mirrors, and line them up in 800 rows of 600 mirrors each. Now attach a hinge to each of those 480,000 mirrors. Attach each of those 480,000 hinges to its own very tiny motor! Power each motor with electrostatic energy!
