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.
I am noticing the same thing after using the images you attached. It looks like a 1 pixel misalignment and occurs at all lens shift positions (even neutral).
While I could easily exchange it, it still scares me that this has happened to a few people already. I fear that these are too fragile and even the excellent warranty doesn't make things great.
I just recently exchanged an HD20 for this, in hopes of improving the picture quality and getting better blacks. Unfortunately, the price to performance increase that I saw hasn't left me very excited (I paid $999 for the HD20 and MSRP for the 8100). This was coming from an HD70 that was working fine, but whose bulb was on its last legs. I really wanted a 1080p projector, but was hoping to improve the image quality at the same time. I don't think I objectively achieved those goals with either projector when considering the costs associated with upgrading.
I have a new bulb coming for the HD70 thanks to a smartly purchased $150 extended warranty from Circuit City three years ago. We will see once that arrives if I have a new appreciation for the HD70 and can live with it for another year or more until I feel the desire to try this again.
Some comparative notes that are aiding this decision (HD20 vs 8100 vs Neither):
1. Blacks are better on the 8100, but not night and day like some have mentioned. I have a dedicated room with some light colored walls, but I still felt like the blacks left something to be desired on the 8100.
2. Fan noise is reduced on the 8100 by a bit, but I still notice the noise more than I did with the HD70. Maybe it is because the HD20 was so loud that it made me pay more attention. Unfortunately now, even the 8100 on eco mode is audible when sitting 3-4 feet from it. Worse yet, the auto iris makes its own rumbling noise that can be quite distracting in quiet scenes.
3. Colors and overall PQ are better, especially when at full brightness. The 8100 would work great in a living room with windows and other ambient light.
Am I crazy? What do you guys think?
