Doublesight DS-263N DVI not working?

[Willhcm]

Hey all,
Looks like any Dvi connections do not seem to be picked up. It was working okay until yesterday, I left the computer for awhile and the screen was just blank. Currently I have resorted to using a DVI to VGA adapter on my video card to connect through the VGA interface. This is an acceptable solution for now but would like to get the most out of my monitor.

I have done the following tests:
1. Tested both DVI ports from the monitor
2. Tested both DVI ports from my video card, and tested a DVI port from my laptop
3. Purchased new DVI Cable.
4. Then I tested the VGA port and this works.

Any ideas on what might be the problem? It seems odd that it just stopped working.

So I got my monitor "repaired" and I when I got it back the DVI ports were working fine. A month later, The DVI ports stopped working again. Once in awhile I can get it to pick up a signal from my video card (4870x2), but if I restart or change resolutions the signal is lost again.

What could possibly explain this ? It was working fine when I got it back from repair!

Anyone else experience issues with their DVI ports and the doublesight 26"?
