The motors tilt their mirrors up to 20 degrees at incredible speeds. This allows the mirrors to modulate light from a lamp, and send the "modulated signal" out through a lens, on to a screen. The most amazing part of DLP micro mirrors, is the scale of size. The 480,000 mirrors (actually 580,000 are used), hinges and motors are packed onto a "wafer" a bit larger than your thumbnail. LCD: LCD stands for liquid crystal display and comes in many forms, sizes, and resolutions. Its primary purpose is to present a digital image for viewing. A common use of LCDs is as a display on a notebook computer. Until recently, it was tough to find a decent 1,000-lumen projector that listed for less than $4,000. Now, you can pick up new 1,000-lumen LCD that the 6.6-pound projector builds on award-winning display technology to provide improved video imaging in a lightweight, easy-to-use design. Introduced at three 0.7-inch LCD display panels produce a native SVGA (800 x 600) resolution and a reported contrast ratio of 400:1.

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 recommended list, weighing 5.3 lbs.

is designed for portable use as well as fixed installation. There is an adequate handle that folds into the side of the unit and becomes almost invisible when not in use. Yes, it is three pounds heavier than the, but if you need to put 2000 ANSI lumens on the screen, three extra pounds is not much to complain about. Activating the focus control puts an inadequate little target up in the middle of the screen, and if you don''t find the plus/minus buttons on the control panel or remote right away, it disappears. The focus control leaves something to be desired. One must toggle back and forth almost constantly just to keep the focus function active and on the screen. The target is so small that it takes several passes through the sweet spot to find the ideal setting. In future products, we would like to see a little more thought put into focusing control. produces a very bright image with a gorgeous color palate. The soft array of colors in was rendered as beautifully as any digital projector we''ve ever seen in this price range. The vibrant colors in were reproduced with accuracy and balance.
