1280 by 800(widescreen) thats the highest my laptop will run .....sadly lol ... i had to do icon clean up because of a full screen of icons.... lol thats only because i put music files and videos on it :X
I don't have that 1280x800. My laptop jumps right to the 1280x1024 from 1280x768. It's widescreen too. It has the ability to go as high as 2048x1536, but I doubt it would look good.
