How To Guide Lock the screen refresh rate to 90HZ/120HZ

[G731882624]

＃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。

#Please note that if you want to restore the settings, you may have to do it again。
settings put system peak_refresh_rate 120
settings put system min_refresh_rate 60

The above commands can also be implemented in the terminal

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.

Try to grant shell root permissions

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

Phone need to be rooted?

Phone need to be rooted?

It will be smoother after rooted. But theoretically not needed

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...

What apps to show this ?
Thank you

Use setedit software it is more straight forward and it doesnct have to be rooted, and it is not reverting back

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.

m12 has unlocked 90 fps on the system, but in games it's still 60 can you help me?

Does this work on Galaxy S20 Fe 5G force 90Hz refresh rate ?
or it's special to xiaomi devices!​

I know this is super old but could you please share the name of font you're using for your screenshot in OP? It looks really neat.
