I'm trying to change my refresh rate to 60hz, because i have a 144hz monitor, as some games act weird above 60hz. However, whenever i restart the computer, the laptop reverts back to 144hz. I have everything updated, and have tried changing the settings in advanced display and then monitor hz, still the same thing happens. After i restart my computer, the screen flashes black for a second then goes back to 144hz. All of this started happening after a clean reinstall of windows 10.
