Well, in my case I am pretty sure that is not the issue. I have four
boxes sharing this monitor via a KVM switch. The others are running at
1280x1024 without any problem. So the monitor can handle it just fine.
Since in my case the problem is with a new machine, it could be
something about the video driver, or something about the software
