Multi monitor help

post #1 of 7
Thread Starter 
Hi,
Basically I have a friend who wants to be able to run 4 monitors off his rig, and he asked if it will work ok with sli,
I said yes, but then I got to thinking and did some looking around and its abit cryptic as to if it’s yes or no to be honest. Say if he was to get x2 270s for example would he be able to run 4 monitors off that? And do you still need to disable sli mode for it to work? or is that in the past now?
It would just be nice to get a straight answer lol.

Thanks.

A friend of mine had 2x8800GTs I believe, and he could run 2 monitors with them in sli, but he had to break the sli to get them to run his 3.

Maybe things have changed now? Sorry for the muddy answer

Yeah thats what i gatherd from google, but as you said, im not to sure if its changed now i know that with some playing around you can missmatch gfx cards to get 3+ monitors but it just seems abit silly that you need to disable sli to be able to use more then 2 monitors.

nvidia's new drivers actually disable mix and match GPUS (i found out when my extra monitors stopped working after the update)

this link should help, it has diagrams at the bottom

Not sure about NVidia but on the ATi/AMD side if you want to enable CrossFire you cannot have any displays connected to the second (CrossFired) card. I would suspect that the same holds true for SLi as the tech is pretty similar.

You can, I am running three displays(surround vision), each display plugged into a single card. SLI works just fine this way.

You have to run 2 monitors per card if you want surround vision. You can run any configuration if you want just 4 monitors (extended desktop, not gaming), and SLI works fine with both.

Gaming would just be done on the main monitor if you aren't running surround vision.
