They said that brightness falls off 40 percent from center of screen to edges, quite high for a projector. Any comment from anyone who knows this projector. By the way, it was also stated that in practice of viewing video this was not that noticeable but it does make me a little nervous. I like the screen to show about same brightness throughout.
I have an H30 and also dealt with 2 others (one I returned and the other was my boss's). I have to say the on the 3 I dealt with, brightness/focus uniformity was not that great. It's true that it's hard to notice anything awry while watching a movie from a normal distance, but it does bother me.
On mine, the left side of the screen is sharp...pixel squares are very apparent and the left screen boarder is sharp. But as you move to the right side of the screen, things start to get fuzzy...the pixel squares start to fade away and the upper and left black screen boarders are now fuzzy instead of sharp boarders. The upside to this I suppose is that you could sit a little closer as the pixels are not as noticeable...but it's not uniform and it seems to be an un-uniform focus issue, which bothers me overall.
Still, I can't seem to notice anything wrong from a normal viewing distance....except for the black screen boarders, I can still clearly see the top and right sides are fuzzy and the left side has a nice sharp black boarder.
And in case anyone thinks it's a keystone issue of some sort, it is not, I've tried all different angles and distances, but the focus problem seems to be internal to the projectors optics. There are pockets of sharpness and fuzziness through out, the fuzziness is not uniform.
I'm guessing this is possibly to be expected on a sub $1500 projector.
It bothers me though.
The other 2 H30's also weren't perfect on this...although the un-uniformity were in different parts of the screen. Just seems that the Q.C. of the optics are not the high point of this projector....on the 3 that I've had experience with.
Wondering if the H31 is any better?
And not to slow Tom's praise down, but my guess is that the H31 he got was probably cherry picked to make sure it was sweet, so while he might have a nice sharp optic H31, others might not be so lucky.
