Hey all,

Does anyone have experience with synchronizing an OpenGL application to a secondary display's vsync? I'm using wglSwapIntervalEXT(1), but from what I can tell that only ties into the primary monitor's vsync.

My OpenGL program only runs in one display (the projector), so I could just swap primary/secondary displays from the Win7 resolution settings window. That's what I'm doing now as a workaround, but it is really tedious and I'd like to get this working in code. Any ideas are welcome.

my setup:
NVIDIA Quadro 4000
Primary monitor: 1440x900 @ 60Hz
Secondary monitor: 1024x768 @ 60Hz

Thanks,
Fredric
