I recently bought the Monsters Inc. DVD (great movie and awesome picture BTW) and noticed that it came with some THX calibration chapters. Since I haven't purchased Avia yet, I figured I'd give the THX screens a shot. During the "circle displayed in two nested rectangles" tests, I noticed that portions of the outer rectangle were NOT displayed on the screen. What is the name of this issue, and how can I fix it? Is this typically a service menu item? During one of the final screens, the vertical lines of the grid are not perfectly straight. More specifically, the topmost portion of the lines bend to the left as they go up the screen. Again, what is the name of this issue and how can I fix it? Finally, I noticed that the convergence was not perfect on the far right and left sides of the screen. The simple nine-point convergence (I have a Pan 53WX42) cannot fix this without interfering with the good convergence on the rest of the screen. Would the service mode 64-point convergence solve this problem? If this is a question better asked in the "basics" forum, then please move this thread. I couldn't find much info from searching in either forum...but I don't know the correct terminology, so I'm probably not using the best keywords.
