|I know exactly what you're talking about. I have a projector. It "shouldn't" be a problem. I have an ATI card and this is what I do:|
Right click on my Desktop
click on Catalyst Control Center
under Display Manager, make sure I see the Main screen and the Clone screen (the projector in my case)
I right click on my Clone monitor (projector) and select "Swap Display Mapping"
And that's it. I can now watch avi's on my projector but now my primary screen has a black video.
For nVidia, i can't help you there.
