Best VGA resolution for the 360? What's closest to 720p?

I used 1280x1024 for a while on my 4:3 monitor. It looked great but you will have problems with the aspect ratio with some games. Basically not all developers have properly implemented 4:3 ratios, so some games will stretch the image to fill the screen, for instance Oblivion. Changing the resolution will not help though (except with PGR3, 1024x768 will give you black bars instead of stretching), so just go for 1280x1024, that's closest to the 360's native res of 1280x720 and properly made games will display exactly that resolution and fill the rest of the screen with black bars.

^^Agree with that!^^
