Issue with single monitor

[Doodleman]

Good morning,

First of all, I am aware of the sticky regarding enabling gaming in the center monitor only. Very helpful I'm sure, but I have run into a weird problem.

My setup is a digital TH2Go, connected to 2 monitors through ports 1 and 3, as recommended by Matrox, on a Win 7 64bit with a Nvidia GTX 295. Yes, 2 monitors. There are reasons for that but they are not relevant to this post.

Now, I am able to get the 3840x1200 resolution going through the wizard. I can even add a single monitor 1900x1200 mode manually through the software. However, when I run the wizard to add a single screen mode, the screens goes blank at the "applying mode" step and it never completes, forcing me to reboot.

If I switch to single screen mode, it runs fine in the left screen. I can then swap it to the center screen, and most of the time it also works fine.

However (here comes the issue), when I try to revert back to dual head mode, the left screen stays blank. Obviously, the desktop is back to 3840x1200 because I'm missing half of the desktop, but I cannot revive the left screen at all. The only solution that works is restoring the factory default config, which deletes all of the above work.

So, two issues I guess: (1) Wizard will not complete a second configuration after the initial one and (2) Once I switch to single screen mode, the left screen will not revive, despite having successfully reverted back to 3840x1200.

Any ideas?
