I managed to overclock my Dell 7567 laptop display using the method outlined here:

So now I can game at 90 Hz/fps even though my panel is rated for 60 Hz. Though my GTX 1050 Ti can have issues hitting 90 fps, but that’s another discussion. Anyway, the CRU utility mentioned in the above post is Windows only. So I can’t get above 60Hz in Linux.
Do I need a custom modeline to force my display past 60Hz? I don’t even know how to begin creating one, especially since the display probably doesn’t have any EDID info for refresh rates past 60 Hz.
