Hi all. I've recently made the switch to linux from windows.
I can't seem to get 4K displaying at 60Hz though (had no problems with in in Windows 7). It's not giving me an option for anything other than 30hz @ 3840x2160.
Is this a driver limitation, or is there a way to force 60Hz?
I'm using an Asus PB279Q 27" Monitor
2 x G1 Gaming 980 tis in SLI
Linux Mint 17.2 Mate
Nvidia 352.30 drivers
Thanks!
