So, I recently bought a monitor to extend my display size and I am having some trouble getting the desktop to extend to my third display. The third display works, but only when I turn another one of my monitors off. I have two displays connected to DVI ports and the last connected to an HDMI port all on the back of my Sapphire HD 7870.

All three displays are detected when I go to the control panel screen resolution tab. When I try to extend the desktop to the third display, it says "Unable to save display changes". Not sure if I need extra software or something.


Edit: Forgot to clarify that I am running Windows 7.

So, if I use an hdmi to DP adapter (2 DVI monitors and one DP), that should do the trick?
