Calling anyone with a Quadro 320M, please help!

Thanks in advance if anyone can help. My HP 8710p contains a Quadro 320M GPU, and it exhibiting extreme colour "fringing" in non-native resolutions. For example:


(mockup of the effect. looks like a badly compressed jpeg)

This effect only occurs in non-native resolutions from 1280x768 upwards. Anything below that, down to 800x600, scales perfectly fine with no fringing effects. That's really odd.

Can anyone with a Quadro 320M please try a non-native resolution, say 1280x800, then look at a colour palette (like the drop-down text colour palette on this forum's text toolbar, or the Colour Settings page in the nVidia control panel) and tell me if you also see this kind of "fringing" at the edges of colour blocks.

Many thanks if you can take a minute to do this.. I need to know if this is a hardware problem with my 320M GPU. If you don't get any fringing at all, please tell me what laptop you have the 320M in, and what driver version you are running.

(For the record, I'm running XP-SP2. Changing drivers hasn't helped, and HP have swapped out my LCD panel twice, with no change either. So I just need to compare this with another machine to see if mine is at fault.)

Please help, this is driving me nuts..
