help hooking up plasma TV as external monitor for R30

[denverhiker]

My apologies if someone's already answered this question, I searched for topics and couldn't find anything.

First - what I have:
R30 type 2656 with Trident Cyberblade video card and standard IBM drivers.
Dell W4200HD Plasma TV with native 1024 x 768 resolution.

I've got this great PIP function on the TV that lets me watch a show while I run applications at the same time. So I want to use the TV as a monitor. Problem is, when I do, the image is squished down (or stretched wide depending on how you want to look at it) on the TV.

I've already tried every resolution offered by the videocard to no avail and I've looked for drivers on the web, but can't find anything.

Any suggestions?
Thanks
