The TV told me I should go with 1360x768....

Since that was not available on the PC display list, I went with 1280x768. Other than those faint lines....everything looks good at that setting and circles don't turn into ovals because of stretching....least not that you would notice. Initially, the setting was 1024x768...and I got the reccomendation from the TV when I tried to change to 1600x900, which is where I am on the widescreen monitor that came with it. I figured it would choke on the 1600....but wanted to see what would happen. It was then when it made it's own reccomendation.
