I've been playing around a bit and I've attached some pictures to show sharpness and convergence. Overall I'm not too happy with how the pictures turned out, as they don't look as good as in real life. One big issue is the screen I rented, it is a cheap tripod setup and there is a large degree of texture on the fabric that is affecting detail. During pans you can easily see the texture showing through the video projecting on it, and it is obscuring the pixel grid. When I put a sample of the JKP Progressive fabric on top of the screen the pixel grid became much more distinct.
With regards to my general impressions, so far I would say I am very pleased. On my unit the focus and uniformity appear excellent. All four corners are focused to the same degree, except possibly the top-right one which could be very slightly sharper (the screen is impacting my evaluation here). There is some CA from the lens, and on the edges it probably gets to be around 1/2 a pixel. From a seating position no CA is visible, however I'm only projecting at 70" and so I can't be 100% confident this will still be the case once I'm at 10' or 12' wide. I haven't seen any rainbows yet, the motion resolution is excellent, there is very little posterization on moving objects, and the auto-iris has been invisible to me so far. The image is sharp corner to corner, and this is especially visible on a Windows desktop. I flipped through the projection modes (rear, front, ceiling, etc.) with the Start Menu displayed and it looked great no matter what corner of the glass it was projected through. I can only imagine how much sharper it will get once I project onto a HT screen instead of this cheapo unit I have.
Two things I noticed when I tried to use ProjectorReviews.com's recommended settings:
- They suggested a red gain of 12 in Movie 1 mode, but on my unit this made everything VERY red. I think things looked better with no gain applied as white looked white this way.
- In their chart Color Enhancement was left at 3 in Movie 1 mode, but I found this introduced a lot of noise in the shadows and things looked better with it set to 0.
