I have seen a number of posts on avsforum regarding colour uniformity problems which I haven't really noticed on mine, i.e. magenta and green in the corners on a grey image. However, having finally got my pixel perfect HTPC stuff done, it became quite clear that I do have a problem with panel alignment. Basically, the red panel is exactly one pixel to the left of both the blue and green panels. As a result everything with a red component has a slight shadow to the left hand side in red. This sounds horrendous, and after all the efforts is of course quite dissapointing, but from any sensible distance is not really all that noticeable. The effect can be seen most easily by going into the OSD service menu and cycling through the red/green/blue images on the bottom option (self check? service mode?). If you look in the corner you can see (on mine at least) that there is an extra row of red pixels on the left hand side and as such, when looking at a any white lines on the RGB input, (of course it would apply to all inputs but is just easier to see on RGB) you can see a slight red shadow to the left. This isn't the case of the panels being slightly out of line, they are perfectly lined up with one panel exactly one pixel off to the side! Can some other people check and see if they have the same problem?
