Hi Jerry_G, I'm not trying to argue with you. I'm trying to collect information about what you are seeing. I never said my TV didn't have overscan, TVs are supposed to have a few % of oveerscan. I'm sure that you realize that different signal inputs (480p, 720p, and 1080i) have different overscan settings on various TVs, right? The question I have for you is this. If you are watching an SD program on the east coast CBS-HD feed which has gray bars on it, when you stretch your picture, do you see the color in the bars change to black? If there is truly underscan happening, then you should see a picture in the middle, surrounded by small gray bars on the sides, surrounded by small black bars afterward. The underscan condition is where the raster on a CRT tv scans the picture with some excess phospher on the tube not being illuminated by the beam. If you are seeing gray bars all the way to the edge of your screen, then there is no underscan of the image. The gray bars to the edge means the raster is scanning and illuminating phospher all the way to the edge.
