Right so i noticed today that my framerate appears to be locked a 30hz when using 4k on my pc. I am using display port to connect the monitor to my gtx 1060. it appears that when i plug a 1080p monitor in as a second display it drops to 4k 30 hz?
This is the 4k monitor: http://www.ebuyer.com/727524-acer-cb241hqk-23-6-4k2k-ips-monitor-um-ub1ee-001
This is the 1080p monitor https://www.asus.com/uk/Monitors/VS248HR/
I am on windows 10 with an I5 6500
i have had the monitor running at 4k 60 hz previously but i am now completely lost as to what could have happened...
any ideas would be greatly appreciated!
