I have a Dell PC running Windows XP. It has the Intel 82915G/GV/910GL chipset. I have it hooked up via VGA to a Sony KDF-E50A10 50" TV. The picture is grainy due to the resolution being at a much lower setting. I want to correct the resolution to 3298x1856. I got these numbers by converting the 50" screen size at 16:9 aspect ratio to LxW in pixels. I tried using REGEDIT to correct the X & Y resolution values and rebooting, but no luck. I have not yet confirmed it but I have my doubts that the integrated video chipset can support resolution values that high. I have a feeling I need to buy a video card that supports large screens, but I figure it can't hurt to ask around for other opinions before I make that move. Any thoughts?
