7950GX2 Problem

[TheOne&OnlyZeke]

My friend just built his new PC
Specs are
Conroe 6700
Asus P5B Deluxe
2GB's 667 DDR2
Creative X-Fi
nVidia 7950GX2
Samsung 913n Syncmaster 19" TFT

Issue is that monitor keeps randomly loosing its native resolution and refresh rate,
Displaying message "Not optimum mode. Recommended mode is 1280x1024 60HZ"
Now the res is set to this and if he plugs a CRT in its still set to this Res.
This is only happening on the new machine as his TFT had no issues on his old build.
Is there any known issue with these cards outputting to TFT's?

latest nVidia drivers are being used and latest BIOS on board aswell

If anyone has any idea's?
