TripleHead2Go Digital with "broken" DVI Input

Postby doom_fury » Fri Nov 09, 2007 5:24 am

I am attempting to make my TH2G to accept DVI input. Whenever I switch to DVI, all my monitors get an "out of range" error. This is quite strange since 75kHz/60Hz is well within specs at 1280x1024. All three monitors can accept DVI inputs and will display fine if plugged directly into the video card. Even stranger is that I can get all three to work perfectly with the exact same settings if I use VGA instead of DVI input on the TH2G. It will also display correctly using a DVI-VGA converter (DVI on the computer, VGA on the TH2G). It also works with only a single monitor plugged into the TH2G and DVI inputs.

Here is my current xorg.conf although I doubt it's an issue. It's a barebones NVidia one I am using for testing.
