Interesting because the Epson is suppose to be 50,000 to 1 contrast compared to 4500:1 for the H79 - and he was only getting black levels about the same....
... I can't seem to get the Epson to focus quite as sharply as my Optoma could, although the difference is slight and may just be a matter of getting a few more hours on the bulb.
DLP is always sharper and its not the bulb, its the technology.
For me, I do a lot of PC gaming on my PJ, so it would have been worth it just to get 1080p, but so far I'm surprisingly pleased with the image quality compared to my old but good DLP. And it certainly is easier to live with - quieter, for one, and the lens shift both ways makes it a heck of a lot easier to place.
The H78 is one of the quietest DLPs around. If you find it too noisy then other DLPs will be worse. Low noise and lens shift is definitely a plus for LCD, but if you permanently mount it, in most cases shifting isn't really necessary.
So here you have an upgrade to 1080p, but its observed to lack sharpness, and the black are about the same despite the supposed 50,000:1 contrast advantage (which is only really potentially achievable in a totally dark room with dark walls/ceiling/furniture) and yet the H78 matches it.
I can attest that my H78 is brighter, sharper, almost as back, more color saturated and noisier than a deep black 1080p Sanyo Z3000 in side by side comparisons (after calibration). Yes the 1080 is slightly more detailed but part of that is negated by less than perfect convergence. After all, 1080 adds only 50% more pixels vertically, compared to 720 but if you have just a 1/2 pixel non-convergence, a lot of your superior resolution is lost in the mud of over lapping pixels colors.
Note that unless you sit very close it will be hard to see the 1080 vs 720 advantage and a number of side by side comparison tests have shown that few people can actually pick the higher resolution machine from a reasonable sitting distance.
I conclude: the H78 is a darkchip3 machine which produces 90% of what a low end 1080p machine is capable of. Upgrading may produce a nicer output, but in my experience, it was not the amazing change I expected, but was incremental and somewhat disappointing (considering my expectations). Disappointing too, because I discovered the joys of non-convergence and non-uniform field color in a LCD (absolutely and eye opener when watching B/W movies, 1/2 the picture is reddish whites and the other half bluish).
What did improve my H78 and other projectors was calibration using a meter, where finally faces weren't unusually orange/red but flesh toned. If you invest in anything, a meter is more important than higher resolution. In fact, resolution is considered the least important compared to color, contrast, brightness and gray scale.
All that said, if you want to get rid of the washed up hulk of a working h78 after you upgrade - shoot me a pvt.
