New computer causing problems with my 2001 FP

[slickpoppa]

Okay, so I just bought a IBM Thinkpad laptop to replace my piece of crap dell and when I try to connect it to my 2001 FP at the full 1600x1200 resolution, the image is kinda screwed up. It is hard to describe, but to the right of any text on the screen there is a weird shadow or ghost image in the same shape as text. This does not happen when the 2001 FP is set at the same resolution as the laptop and it doesnt happen on the laptop's LCD.

Has anyone experienced anything like this? What the hell could this be? Is my hardware screwed up or could it be a software problem? The video card is an ATI Radeon 7500
