Can a single gtx 780 support 3 2560x1440p monitors

Nemke Besevic · Mar 9, 2014

I own a gtx 780 and I am going to buy three new monitors that each run at 1440p, I'm interested if I could run games like Battlefield 4 on all three monitors or would I have to buy a second gtx 780? Would two 780's run it?

"would I have to buy a second gtx780"? Yes
"would two 780's run it" You would have to turn graphics down but yes.

Well, the problem you are going to have is that those monitors only have a DisplayPort connection (since according to Asus, G-sync is presently only supported on DP connections). They don't appear to support daisy-chaining either. That card only has one DP output. You would need a DP MST hub, but I'm not sure that the hubs are compatible with g-sync or if there are hubs that support 3 x 1440p monitors.

Wish I knew, someone around here should, but you'll need to find out 1) Does G-sync work with DP MST hubs? and 2) Is there a DP MST hub that will fully support 3 x 1440p @120hz monitors using only one DP port?

Also - performance-wise you'll be needing to have 2 x 780 instead of just one. Performance on one will be dreadful. Even two will require reduced settings. And you'd still need a DP hub.
