1080 should work fine. Try reinstalling the nvidia driver
False i had one 1080 that it ran at 100 fps one regular 1080 can run overwatch on epic at 160+frames dual 200+ one 1080ti 180+ there is no reason why it isn't working unless you have a crappy Display port cord the one Asus provided is the one i am using so ....
You also tried monitor controls right ?
Also i'm going to say only HDMI is locked on 60hrz you are positive you are using the right cable
#1 HDMI
#2 Display Port
#3 USB
The Hdmi and Display look the same but the ends are slightly different i am saying this as that could be the wrong cable mistaken for the other
