Also was there much of a change in the 720p to the 1080p? Thanks
Funnily enough I'm running mine on a 106" screen also, it's a DaLite 1.0 gain flat-white vinyl. I also felt that the Mits was slightly dark (I ran in low bulb w/ Brilliant Color off mostly), and a little ambient light always washed the picture out.
There is no doubt that the Epson is brighter...currently I'm running it in eco-mode with dynamic iris off. In that mode I find that the black-level floor is approximately the same as the Mitsu, BUT the brightness is much brighter, I'd guestimate in the 60-70% range. In full-power mode the brightness kicks up another notch or so but I think it's actually too bright on a screen of my size.
The difference between 720p and 1080p is definitely source-relative. HDTV seems marginally improved, but there is a downside in that I notice more of the compression artifacts / image noise than I did on the Mits (my provider is ATT U-verse). In other words, it seems like the 720p was masking some of the image noise by virtue of its reduced pixel count.
On BD the difference is much more dramatic...there I definitely see the benefit of the 1080p. As an example, I can actually see the grain of the film on some movies, which I never once witnessed using the Mits. I bet this is partly due to the 24fps input too, but either way the net result is really amazing.
So far I've done all my viewing at night but tomorrow I plan on an NFL marathon so I'll see how it performs under ambient light. Also, I plan on doing some gaming / web browsing this weekend so I think that will be a good test of the sharpness too.
