Hello, Recently i update my X-Org fron 6.8 to 7.0, and earlier i had the ability to change my Screen refresh rate in screen resolution under Gnome Screen Resolution app, now i can change the resolution but the refresh rate stays on 85 Hz, in a personal way i preffer 75 Hz of Vertical Refresh.

check what refresh rate ur monitors are running at. kde reports my refresh rate is 50hz but both my monitors say they are running at 75hz.
