Was habt Ihr gegen (weitere) Testwerte?
Nichts, aber für mich sind sie in der Praxis nicht relevant.
So sehe ich das auch:
ZitatWe used a projector that measured just over 1000:1 ANSI for direct comparisons against the JVC RS35. We spent several hours trying to find content that we felt made a visible case for high ANSI vs run of the mill ANSI and couldn't do it. Sequential contrast differences were extremely apparent, but mixed contrast differences were only apparent using the actual ANSI contrast patterns. This has been my experience with EVERY comparison I've done, and I've done a lot of them. I still think this has a lot to do with the way image sensitivity works with our eyes and the fact that as you move up in APL, the amount of area that is actually black reduces substantially and is surrounded by other colors/whites that you are optically comparing to and fill in the black. This is why it is so easy to make a DLP look like it has fantastic blacks, just pick the right demo material and I can make someone believe a 2000:1 sequential projector has fantastic inky blacks. Trade shows have done it for years.
Obviously having high dynamic range at all APLs is something to strive for, but I think there is definitely a floor that is reached where the difference becomes unimportant or trivial because of how the eye works with perceived contrast. I think you'll see a difference when staring at a test pattern, but most test patterns for ADL contrast have almost zero bearing to actual video content because they only display full white and black images and that will almost never be the case as you move up from black in ADL. This is what extremely low ADL is so difficult, you have large areas of black with nothing on the screen to bias/compare the black to except more black. So if your black floor isn't good, it has nowhere to hide.
