Which TV is Best:
LCD, Plasma, DLP, LCoS or LCD Rear Projection?
DLP Front or Rear Projection TV
Another strong point is the lack of pixelation. LCD panels have a matrix dividing each pixel, and this shows up, to some extent, on the screen. With DLP, there is no matrix and thus it has a more even texture. However, because of the mirrors, images tend to have a sharper edge appearance. Some people find this appealing while others find it to have more of a "video" than "film" look.
Another issue with one-chip DLP is that the color wheel can lead to the "rainbow" effect. Most people do not notice it, but some find the shifting rainbow of color to be distracting. Some people even find it very objectionable because it gives them headaches. Newer models utilize 3 colored LEDS instead of a color wheel which reduces the chance of a rainbow effect. 3 chip models eliminate the problem altogether.
Finally, the mirrors are mechanical in nature and thus are prone to mechanical malfunction. A mirror can become stuck, either on or off, resulting in a single pixel remaining fixed on the screen. In many cases, a single pixel will not be noticeable. However, in certain circumstances it can stand out glaringly and even more so if a cluster of mirrors are affected.
DLP overall, delivers excellent images, its drawbacks should not be enough to dissuade most viewers, unless of course you find the rainbow effect personally distracting. Because of its price and wide availability, many choices abound for DLP TVs. Currently, most DLP TVs have a resolution of 1280 x 720 (720p) or 1920 x 1080 (1080p).
