SLI & 2 Monitors

Clareman

Hi all,

First time posting in this forum, I searched for similar threads and couldn't find anything.

I have 2 graphic cards in my system (Nvidea 7900s) and have them linked via SLI, I decided to get another monitor, unfortunetly I can't get the 2 of them to work if I enable SLI, I have to disable the SLI and they work perfectly, for gaming this is a bit of a pain

Just wondering if anyone here was able to get 2 monitors to work on a SLI monitor

Not possible I'm afraid a limitation of SLI means only one display can be used.

The only way round it is to get a third graphics card so a simple PCI or PCI-e x1 card may work though it can be awkward to setup apparently.

Specifically when SLI is active the NVIDIA driver disables all outputs on graphics cards bar the primary so if you stick another NVIDIA card in there it will do nothing. So the solution is to use an old ATI card and hope that the built in driver in Windows will suffice or at least just install the display driver without the ATI control panel and that works for some.

The last option is Matrox Dual or TripleHead2Go which takes the output from the primary card and splits it externally works with SLI but is VGA only.

thanks 8T8, much appreciated, that's what I feared, most of my slots are filled at the moment and I'm not a believer in downgrading systems which a 3rd card would be

At the moment I'm just turning SLI on if I'm playing a game
