Screen fails to return from power-save
 

When in power-save, I move the mouse, everything shows up just fine but the DisplayLink screen stays black. To fix this, I right-click on one of my working displays and click "refresh"; then it works.

Two ATi HD4850 in Crossfire with 10.9. Windows 7 64-bit.

I have been testing this many times. If I move the mouse, the screen comes back, right now the screen is black, this is because I brought the computer back from power-save using the CTRL key. I'm under the impression there's a driver bug which causes the display not to respond from D2 to D3 if a key is pressed.

Can someone else confirm this for me please?

The reason why you're experiencing such issues is that crossfire GPU configuration is currently unsupported and will not function properly on Windows 7/Vista.
