You have to go in display settings, then scroll to the bottom and click "advanced settings". Select the display you have trouble with, then change the refresh rate at the bottom.
Warning that you can damage things if you go too high, if it isn't 60 I'd suggest trying a lower one, or if it is not a round number, try 60. Most of the time higher refresh rates are blocked anyway so you can't screw it up, but if you see them above 75, here be dragons.
