Default Re: Rear Projection at CEDIA - missing???

Hi All,

Actually the human eye can only see 1200:1 in the dark. The other thing about Contrast Ratio is that the environment (read: The Room) is a huge variable that has a major impact on the real contrast ratio achieved. What you typically get in a movie theater is around 180:1 as a point of reference. If you design a home theater well, and calibrate the display properly you might acheive a Real World Contrast Ratio of 500 or 600:1, and that my friends is outstanding! The Contrast Ratio spec war is the industry's latest stupidity. In the late 1990s projector manufacturers were doing the same thing with light output in Lumens before the industry moved to ANSI lumens. Sam Runco called them Bull**** Lumens!
