My PCs graphics card is a VIA UniChrome Pro III. The TV is a Digistar 27 inch LCD and supports a 1280 x 800 resolution.
Under Screen Resolution in Windows 7, I can choose 1280x800 and 1280x768, but both result in the TV going to 1024 x 768. However if I set the resolution to 1280x1024 the TV gets set to this.
What could be wrong? Why does it refuse HD resolutions?
