All other things being equal, sync to the CRTC of the primary output.

Does this patch work for making 3D and video synchronize to the primary output by default?

Yes, excellent: At least for me, the moving tear line is always on the display which is *not* primary.

Even works when switching on-the-fly, for already-running applications.
