Hi LG. I think there is a difference between speced native on\\off and useable on\\off. With the RS20 for example, while 50,000 was obtainable with the iris set toits smallest opening, most could not do this without making the picture too dim. Nevertheless,usuable on\\off on the RS20 is high enough to reach a gammma of 2.5 without crush.Ref blacklevels still have a way to go with fade to blacks still looking quite gray.
Raising native to 80,000, might result in a usuable on\\off in the 60,000 to 70,000 area. Unfortunately this will not result in much visable improvement. While gamma could be raised, historical testing has shown that things get too contrasty once gammas get much higher than 2.5. Remember using a gamma of 2.5 is clearly a viewer preference. Some like it, others prefer a lower gamma. but clearly, once gamma gets above 2.6, things will be too contrasty to look real.
The real benefit here of raising the on\\off above RS20 levels is the inherent lowering of the black ref level.. In this area, we have a long way to go and a useable on\\off of even 80,000 doesn`t get us there.
I am sorry but those who rant about the deficiencies of a DI and applaud JVC for not offering the choice of using one are . . . . As long as the user can switch a DI off, they would not suffer if JVC included one.doing so would not be very expensive and I think would lead to very increased sales because JVC would trample the 3 chip market.
Condoning the metered improvement, heh heh, will give em 30,000 more this year when for a few bucks we could give them say 200,000 more is a travisty.
i have more to say but there is little point in saying it. A DI from JVC is not going to happen and that`s a shame for many of us.
