I tried using my 30 inch TV as an additional monitor for my PC. The image of the desktop and the text in windows is blurry and nearly impossible to read. The only time the screen image is satisfactorily clear is when I am gaming in full screen mode or if I am showing a PowerPoint presentation in full screen mode. I have an ATI Radeon 9000 Video card with both VGA and DVI outputs and it also has S-Video and Composite outputs for a TV. Any ideas on what I need to do in order to get my TV screen to look legible?
