All 3 of my TSU9600's only have a 638x480 visible screen area. The frame overlay image I use for my DVD cover image pages is a good example of how I need to account for this. See below.



The frame overlay image as shown above is positioned on top of the actual DVD cover image buttons. If you look closely you'll notice that the black border on the right side is two pixels wider than the left side. The right side is 3 pixels wide. The left side is 1 pixel wide. Originally when creating the frame overlay image I had the border 2 pixels wide on each side. Once downloaded to the remote however, the black border was not present on the right side. This is when I discovered that the last 2 vertical pixel rows of the 640x480 page area were not visible on the remote. As such, I simply updated the image to account for this as shown above. Now when downloading to the remote the black border is visible on the left and right sides, each 1 pixel wide.
