I recently bought and installed a Palit Geforce GTX 460 1Gb - the sonic
platinum edition. While the card powers my Relisys tl795 r-u monitor
brilliantly, neither DVI ports work properly. I get a bright green
background to everything.

I've tried three different DVI cables with the same result.

My monitor worked perfectly well from the DVI port on my previous
Geforce 5600 card.

Before I go through all the hassle of sending the card back - does
anyone have any experience of the problem? Could it be the monitor?

Someone here may be reporting the same thing - more modern video
card, DVI output, TL795. It would appear, something happens to
the monitor, after it is run via VGA. Then DVI is screwed up afterwards.

The VGA port apparently still works normally. Weird.

I'd probably start with Moninfo, and see if the EDID still works.
Perhaps the EDID got corrupted ?

The EDID should work, whether you're connected via VGA or DVI.
Communication with it, is serial, via a couple pins on the cable.

I wouldn't trash the video card just yet.
