AMD Triple Monitor Issue

post #1 of 3
Thread Starter 
So I recently procured a Radeon 7950 after running GeForce for nearly 10 years. Needless to say I was very excited when I found out that my one Radeon could support 3 monitors where as all of my Nvidia cards would only do 2. So I finally got around to ordering a couple of mini-display to HDMI cables to get my third monitor up and running, only to be presented with maddening messages from both Windows and Catalyst when attempting to set it up. After doing some research, I found many instances of people stating that if using a DVI cable, you need to have an active adapter, but have failed to find anything of consequence about using miniDP cables themselves.

Catalyst Message:

"To extend the desktop, a desktop or display must be disabled."

Windows Message:

"The display settings could not be saved. Please try a different combination of display settings."

Sapphire 7950:

Mini-Display Port to HDMI:

My current setup is Asus VG236 - DVI-DL, Vizio E3D420VX - HDMI, Samsung T260 - MiniDP to HDMI.

I don't really care about Eyefinity, just want 3 monitor extended desktop, but from what I have read this may still be considered Eyefinity. I am hoping I don't have to order another part, but if so, so be it. Also, I do have an extra MiniDP to HDMI cable that I had order for on-the-go with my Surface Pro, but can replace the DVI with it if I need to.

Any suggestions/help from the amazing people at Overclock will be sincerely appreciated.

It's an actual cable, not an adapter. That's the main reason I was having issues finding helpful info. Everything I was reading about was talking about adapters.
