Well, I have two monitors and my game is not playing on the primary, but on the secondary. And I can't seem to switch it to the primary one. However, in the resolution options I my video card is listed 2 times, but I cannot seem to change that.

Have you tried disabling one of the screens while playing? Atleast that fixed the problem for me.

I am having the same problem.

I really don't want to disable my other two monitors.
I do a lot of multitasking and need them on.

It seems to me their is a registry key:

HKEY_CURRENT_USER\Software\JoWooD\DV2Addon
key name: video.device

It is set to all zero's which is not my primary center monitor (assuming this is the right key).

I have tried 1, 2, 3, etc. with no effect.
Can someone from GOG tell us how to change monitors in this game?

Thanks!
