Monitor can DEFINITELY handle the resolution: 17" monitor, I was running 1024x768@60hz. I've run the monitor before @ 1152x864/75hz. The display definitely looks like a bit-shifting problem within either the card, or the driver. :P

I've tried every color depth @ 640x480. Same diff.

Looked over the rendition driver @ xfree86.org - same diff. By the way, the driver hasn't been updated since 3.frog-knows.

I'm almost 100% certain the problem is the card now. :P
