As far as I know Microsoft''s support for OpenGL on more than just the primary monitor is very sketchy . . .

I know for a fact that you can''t have different OpenGL implementations (ie. different cards) working together, if they both have single outputs. I tried for a very long time to get this to work, but from what I gather, (from the opengl.org forums) Microsoft just doesn''t let it happen. Somebody correct me if I''m wrong, please!

But if your GeForce 4 has dual outputs on it''s own, (I''m not really sure about this, I only have a GF3 with a single output ) maybe there''s a hardware-specific way to implement it, but you probably can''t get something going generally.

thats right.

If i drag an openGL game, or app into my secondary monitor, i no longer see refreshs. the only way to work around the problem is reneder your opengl into a back buffer and update the display using overlay.

You are having trouble getting single-monitor OpenGL apps running when you have both monitors enabled? That used to happen to me - doesn''t anymore though. Guess it was a driver issue.
