As I previously stated, without the folded paper shim, the image is about 1/2" lower on the right than the left, this appears to be a rotated, not warped image, and is effectively cured with a shim under the right front corner of the foot. This leaves the slight curvature, or bowing seen at the bottom of the picture. Theres an almost imperceptable hump in the middle of the bottom of the screen, with a slight dip to its left, and a final upturn on the outer 8" of the screen. Measured across the bottom, from the lower edge to the top of the menu bar, at approx 6" intervals, it goes 5 5/8", 5 1/2", 5 7/16", 5 1/2", 5 9/16", 5 1/2", 5 1/2", 5 1/2", 5 1/2". This is with the shim in place.
Given that this effect is only really found near the bottom of the screen, and is nullified at the edges, this seems to be due to the screen bowing outward slightly under its weight, and I feel secure that it could be resolved with a rehanging of the screen.
One of the more interesting issues that came up as I ran the test screens from the USB port was that the TV did not like to resolve the images very well. I have attached a few examples.
The TV seems perfectly capable of being able to resolve one pixel thick lines or characters in some cases, but seems to not have true detail resolution for the most part. The moire effect comes in on a much coarser pattern than I'd like. So, heres the question: Is this a limitation of the image processing of the TV, or is this a limitation of the picture quality of the USB input, or what? Is there a way to make the image more precise? I suppose I could try to get DVI-HDMI cable and see how it displays a direct PC output, but I'm interested to hear ideas.
