I have a left screen for two monitors on the GT 740, a middle screen for the 4K and two monitors on the GTX 970 and a right screen for the two remaining monitors on the GT 740. Note that Gnome did not handle multiple X screens well but XFCE handles three X screens like a champ. #LINUX VIDEO CARDS FOR 4K MONITORS DRIVER#I'm using Ubuntu 14.04.03 with XFCE and the 958 Nvidia driver package from (Steam crashes on 358, 352 is recommended). #LINUX VIDEO CARDS FOR 4K MONITORS UPDATE#Update Jan 8, 2015: I now have 7 monitors (including a 4K and with capability for an 8th) running on two video cards (GTX 970 and GT 740) in an Asus Z170-K motherboard. I had to add a second "screen" in my "server layout" which I did with that settings app. I was able to configure the cards with the Nvidia X Server Settings app. I'm using the Nvidia 331.113 binary drivers. I got six monitors working in Ubuntu 14.04 by using a GeForce GT 640 and a GeForce GT 740. In my opinion Unity is the best System for multi-monitoring. Just for clarification, I'm running a stock Ubuntu 13.10 daily. Unfortunately the open source driver isn't supporting crossfire, but maybe this could also work across multiple cards without crossfire. There should be no problems running this with as many monitors as you like, as long as you can attach them to one card. Since then the flickering problem is gone and this setup really runs perfectly. Since last week I'm running the Ubuntu daily image because of the 3.11 kernel, which is featuring the new AMD open source driver. It's running perfectly, although the closed source driver is causing some flickering. I currently run four of those with the GPU equivalent from the 6xxx series. Those are really inexpensive but have an IPS-Panel and all the inputs you need. Those cards are extremely silent and you can attach six monitors.įor monitors I would use the Dell UltraSharp U2312HM. I would go with a ASUS EAH7970 DC2T/3GD5.
