Why Can't I Get Surround Working

There is a good chance the answer is because I'm an idiot and the answer is staring me right in the face but I've tried the following setups with no luck;

All three monitors show and work fine with SLI disabled but as soon as I switch to span displays (SLI enabled) I lose the screen on the second card. I know if you want 3D surround the displays must be identical but I was under the impression that with 2D it didn't matter.

This is how it's currently setup.

It's a right pain in the backside. The drivers are terrible for Surround!

Tried to enable SLI on one monitor and THEN enable Surround?

SLI bridge is installed correctly?

Try it with them all in DVI as well (I know you have already but keep it like that).

So centre monitor in card one DVI one, monitor on the left in card one DVI two and then the right monitor in card two DVI one.

Remember you'll need to run at 60 Hz in surround as your other two monitors aren't 120 Hz.
 
Bridge is correctly installed and definitly working in SLI when gaming on one monitor. All screens set to 60Hz. Drivers installed. All plugged in with DVI. This is what I end up with

Shows three screens in SLI but only have two available.

I've been considering 3D surround but the expense just doesn't seem worth it if it's this much hassle to setup.

One thing - can you run single screen in SLI with the other monitors enabled and in extended desktop mode?

No, I always lose one screen when in SLI. If I put it in 3D mode for example I have the main display for gaming and one other in desktop mode, the other is disabled.
 
Don't worry about 3D for now and concentrate on getting the monitors to join as one.

If you enable SLI can you run with all 3 monitors plugged into GPU1 with extended desktop mode active?

I've tried all three on one card. Two DVI and one DP but still lose one when in SLI.
 
ive got surround working with no trouble at all with a single 670, are you able to get it setup on a single card to start with before adding the additional issue of SLI?

I've tried plugging all monitors into one card but that doesn't work. SLI has to be enabled to span the displays in surround. The only way I could try it with just one card is to remove the second one which isn't really an option.

No you can run all off one card - try that as well.

3rd will have to go in via HDMI or Displayport but it at least would isolate SLI as the issue.

can you not disable the 2nd card in device manager and test it works okay with 1 card?

+1 for 304.79 driver too
Click to expand...

Yes. Try that :).

I know it's a pain but unfortunately nVidia don't like Surround users that much at the moment and the support for it is a little shaky. It either works or it doesn't.

It works OK for me fine but when I try to go back to extended desktop mode I have to re-do the bezel correction. Also while disabling SLI sometimes it gets stuck and both cards get disabled in Device Manager leaving me with a black screen....
 
Just tried 304.79 got a red screen to start with then dropped to 640. Looked okay after a restart but SLI was disabled. Tried to enable but would revert straight back to disabled again. Back on previous drivers and desktop is back to normal. I will have to try with one card.

I only have a display port adaptor rather than DP to DP, will that make a difference?
