I'm using a CRT, so it's not an issue with scaling. I pretty much use only PAL and NTSC screenmodes.
Glad to hear I'm not the only one with issues and that a fix may exist. Unfortunately my VGA cable is integrated into the monitor so I can't well just try another one. Sigh.
It's my only monitor, but I'll take the computer somewhere and test it with other monitors and cables to see if that's the problem. Thanks!
