DLP technology is used in rear projection TV’s and projectors. DLP technology can create 16.7 million to 35 trillion colors and 10,000:1 contrast (Same as high end plasma). With DLP you get a bright picture and same quality as Plasma TV’s. As a result DLP can be viewed in bright rooms. DLP projectors offer several advantages over projector systems, for a modestly higher price — along with video performance that's superior in some ways to more expensive projectors.

• Make sure DLP is HD and displays at 16:9 aspect ratio.
• Choose models that are 720p or higher horizontal lines of resolution.
• Make sure model is XGA,UXGA, or WXGA.
• Make sure has DVI or HDMI input
• Contrast Ratio 1000:1 or geater
• Brightness (controled lighting enviroment 1000 lumens or less) (excess light areas or ambient light 1500 lumens or greater)
• Make sure to look before you buy.
• Once you find the model you like, check online for information and problems with model. Also see if another manufacturer offers a better product for around the same price.

• Make sure DLP is at least 1024 x 768.
• Choose Models that are XGA or UXGA
• Contrast Ratio 600:1 or geater
• Brightness 1500 lumens or greater
• Make sure to look before you buy.
• Once you find the model you like, check online for information and problems with model. Also see if another manufacturer offers a better product for around the same price.

DLP projectors deliver excellent picture quality. The DLP light engine is capable of very high brightness (though not as bright as LCD), so a DLP set can be viewed even in bright room conditions. Because of DLP's fine reproduction of blacks, its contrast performance is superior to other projector technologies. The single-light-source design eliminates the convergence issues that plague some other projection systems, and limits maintenance costs (a single bulb to replace, for example).

Disadvantages:

Certain especially sensitive viewers notice an artifact commonly referred to as the "rainbow effect," a consequence of DLP's temporal approach to color formulation. Those viewers may momentarily see the light split into its component color spectra as their eyes travel quickly from one part of the screen to another — particularly when seated close to the screen. The unlucky few will likely find this quite distracting; fortunately, most viewers won't even perceive a problem. The latest-model DLP projectors incorporate improved color-wheel technology in an effort to further minimize this artifact.
