6950 Eyefinity - Third monitor is disabled while the other two are laughing.

post #1 of 8
Thread Starter 
I have two monitors detected but when I try extending the third monitor, it says "to extend the desktop, a desktop or display must be disabled". When I click ok, one working monitor turns off while the non-working monitor turns on. Any idea how to fix this issue?

Other info:
I uninstalled my ati driver, cleared out the ATI with driver sweeper and installed CCC Version 2011.0908.1344.23115.

Monitor to graphics card
Monitor 1: VGA > DVI adapter
Monitor 2: DVI > DVI
Monitor 3: DVI > Mini displayport

You need an active adapter. Sounds like the one you are using now is passive. If the adapter is passive, that error message is produced.

Is your adapter DVI to mini DP? If so, you have an adapter for macs which wont work for Eyefinity.

What you want is an active DP to DVI or a passive DP to VGA.
Take note it's DP. Then you use your DP to MiniDp cable that came with your card

That for sure will work. Quite pricey though.

This one cheaper but youll have to see for yourself if it works.

Get this one. It even says eyefinity validated. This should work.

Monitor to graphics card
Monitor 1: VGA > DVI adapter
Monitor 2: DVI > DVI
Monitor 3: DVI > Mini displayport

The best configuration to setup Eyefinity for your 6950:

Monitor 1: Native DVI > DVI

Monitor 2: Native DVI > DVI

Monitor 3:

- If it doesn't have native DVI then must use > VGA-MiniDP Adapter for resolution 1920x1200 [ame="http://www.amazon.com/Accell-B101B-002B-UltraAV-DisplayPort-Adapter/dp/B0041O7XHY/ref=sr_1_2?ie=UTF8&qid=1318381377&sr=8-2"]Amazon.com: Accell B101B-002B UltraAV Mini DisplayPort to VGA Adapter: Electronics[/ame]

The above adapters are validated by AMD. If you buy other than the above, it's a hit or miss and not guaranteed to work for Eyeninity. Refer to the model number if you want to pick it up from Frys.

Thanks ken, I ended up using config #2. The guy who sold me the adapter claimed it was active so I ran with the idea that it might've been something else.
