About 2 weeks ago I spontaneously purchased a 8100 because of the BB deal at the time. This is my first LCD projector (I've only used DLPs before) and I am very happy with it for movie watching (BR).
However, I noticed some color seams around text when displaying a computer desktop. So I made some test patterns (attached) and took some closeup pictures (attached). I noticed the following things.
1. As you can see, there is noticeable color separation in both horizontal and vertical direction, especially in the lower right corner.
2. The upper left corner seems to have less contrast than the rest of the image.
3. All horizontal lines are somehow blurry.
I am not sure whether these things are caused by panel misalignment, chromatic aberration of the lens, or both.
I am projecting on a 135" screen. The projector is placed on a low table with the center of the lens approximately at the same height as the lower edge of the projected image, using only vertical lens shift of about half the shift range.
I would appreciate if you could try my test patterns on your machines and post some closeups of the corners and center.
