It's not even a matter of being spoiled by LCoS, that's bad by DLP standards. My 10 year old Planar 8150 has nearly 3x the native contrast and a very effective DI.
Yeah, it's a shame that contrast performance seems to have taken steps backwards with this new chip. Texas Instruments really should do everything they can to try and figure out a way to improve contrast performance. If this can't be done with a single chip design, then it's about time to start experimenting with double stacked-DMD systems.
Perhaps they feel that the light loss from doing this is too big for it to sell? I think it would be nice to have the option. A DLP projector with 1000-1100 lumens max, but with fantastic on/off contrast and all the other inherent qualities that DLP can deliver, would be a really nice option for people with smaller screens (like myself).
