Framerate locks to 30fps with vsync enabled in eyefinity

This really seems like a driver bug or hardware limitation. It should be possible to synchronize with a particular monitor, but clearly this isn't happening. Passive DP to DVI adapters will act like single-link DVI ports, so that might help work around the problem, but then HDMI should have worked as well.

The range limits don't matter on the Dells. That's mainly information about what the monitor will accept, and it might not even be accurate. On the HP, the V rate controls the FreeSync range, and the min/max H rate always matches when FreeSync is enabled.
