In response to musykman
I saw a new Samsung with 25000:1...
Who said it was that high?? Wait, let me guess... Samsung???
That number is pure BS, and unless you know how it was measured, it's absolutely meaningless.
The standard ANSI method of measuring contrast ratio is to have a pattern of a black and white checker board on the screen, and you measure the difference between a white square and an adjacent black square.
Your Hitachi will measure a contrast ratio of about 100, when measured this way, and I'm sure the Samsung will also be in that neighborhood.
