Video Projector Technology

I've always been interested in video projector technology ever since a friend of mine turned his driveway into a drive-in movie for a summer dinner party. Since the price is coming down on these things as fast on these things, having your own home theater is now in reach people who earn less than Bill Gates.

Tom's hardware has a good primer
for selecting a video projector. I'll paraphrase the advantages and disadvantages of the technologies but it's well worth reading the whole article if you are technically inclined.

  • DLP Technology
    • Advantages
      • Brilliant, colorful, clear image
      • Good contrast
      • Light output high (low loss with fewer mirrors)
    • Disadvantages
      • Possible rainbow effect in lighter areas
      • Price
  • LCD Technology
    • Advantages
      • Less expensive
      • Newer models now have better light output
    • Disadvantages
      • Black colors don't come out black
      • Crystal matrix can be seen at close distances
  • D-ILA Technology
    • Advantages
      • Blacks are darker
      • Good contrast
    • Disadvantages
      • Expensive
      • Noiser fans due to high heat
  • CRT Technology
    • Advantages
      • High resolution
      • Good fluid motion
      • Best rendition of black color
    • Disadvantages
      • Big and bulky
      • Works in fixed location only
      • Difficult to setup and calibrate

Before purchasing a projector, I'd highly recommend reading the whole article because there are a lot of consideration even if you select among the possible technologies.
