Desktop Display stuck at 640x480 with hd5870

[flyswatta]

I'm running an HD5870 headless and when I connect via VNC the resolution is at  640x480.  That's the only resolution that I can get. It worked fine with my hd5830 in there so it has something to do with the new card. I have it located in a place where there's not really room for a monitor, so I'd like to figure out how to get this to work without having to plug in a monitor.  I had Catalyst 11.6 installed and applied the 11.6b beta patch that supposed to allow multiple monitors to work without dummy plugs (waiting on some extenders from cablesaurus so I can run the 5870 and 5830 on the same mobo).

Anyway, any suggestions or ideas would be greatly appreciated!

Windows normally requires a reboot when changing video cards but I'm hiding you've tried that already heaver you given uninstalling and reinstalling the drivers a shot?

Yes, I rebooted.  It works fine when I have a monitor plugged in, so I think i need to make a dummy plug.  I'm going to give that a shot.
