I recently took delivery of a Panasonic TC-P65GT50 and overall I'm extremely happy with it. However, upon doing some preliminary calibration and testing on it, I noticed something strange. I loaded up the Disney WOW disc and when viewing the "Overscan" test image, I noticed that the rightmost column of pixels is not being displayed! I have the television's aspect ratio adjustment set to HD2, which is supposed to produce a 1:1 pixel mapped image. And when viewing the 1 pixel checkerboards and other scaling test patterns, the display does appear to have 1:1 pixel mapping, except for the small fact that it is not displaying that last vertical line! Just to make sure it's not that particular test image, I brought up the "Aspect Ratio" image, and the same thing is happening - I see a 3 pixel thick white border along the left, top and bottom of the image, but the right border is only 2 pixels thick.
Has anyone else noticed this phenomenon or have any idea why this might be happening? It doesn't bother me since it does appear to have proper 1:1 mapping, it's just very curious. Could it be the Blu-ray player? I have a Sony BDP-S590 hooked up to the TV via HDMI. Could it be the DIsney WOW disc - maybe their test images are incorrect?
Anyway, thanks for any insight!
