It has nothing to do with what your monitor can handle.
In your case it seems like it is the monitor that is setting the limit. But if you had a external 1280x1024 monitor it would be the graphics card that was setting the limit. On modern graphics cards you cant be sure all graphics modes has a corresponding entry in the VESA bios. This is mostly a problem with widescreens. I have a couple of laptops with 1280x800 LCD panels but the VESA bios hasn't a mode for it. This is only a problem if you have to use a vesa driver. -moj > Thanks > > Jan
