#Enter the shell on the PC
adb shell
#Modify peak and minimum refresh rate
settings put system peak_refresh_rate 90
settings put system min_refresh_rate 90


Yes, you have got a global refresh rate setting that will not be invalid even if you restart。

It did not work for me. I get an error message:

java.lang.SecurityException: com.android.shell was not granted this permission: android.permission.WRITE_SETTINGS.

how do you get the settings to stick? it changes on the screen I'm on but as soon as i exit out of it on the phone it reverts back to 120hz

Sorted it. Didnt know i needed to go onto 60hz for it to enable 90

what exactly is it your entering? can you simply list the commands? tried everything i know....this is nothing like fastboot to me lol

nevermind, after a bit of looking (more like 40 seconds, i found the commands lol and added the rest i needed)

to me it would seem that 90hz is extremely jittery (run a game and switch between 60 and 90 using adb shell. youll see what im speaking of.....not so great....when 60 looks smoother...

All the above comments work for me in Normal mode. In power saving mode it is switching back to 60. There should a variable to edit screen rate in power saving mode. Anyone knows? Please advice.
