Auto switch between FHD @120hz & WQHD @60Hz on per app basis

UPDATE 09/12/20
EDIT: LOOKS LIKE BIXBY ROUTINES WAS UPDATED TO SUPPORT MOTION SMOOTHNESS AND SCREEN RESOLUTION AUTO SWITCHING, SO NO NEED FOR THE DYNAMIC DISPLAY APP OR ADB ANYMORE!
SETUP BIXBY ROUTINE
Settings
Advanced features
Bixby Routines
Add (+)
You can add an application (app opened) of your choice or whatever else you want
Under display you can select Motion Smoothness and Screen resolution
(In my case I selected Standard and WQHD+ for YouTube)
No need to create an exit routine, when you leave the app it will revert back to your original settings (in my case FHD+ Adaptive)

This doesn't seem to work for me. When it is supposed to switch back to 1080p 120hz (adaptive refresh) , it changes to 1080p 60hz (standard refresh).

You need to use the app that I linked. The link takes you too a reddit page where you need to get it from Github. Thats the app for the FPS. The Bixby routine is only for the resolution and only have of the steps needed.

I've used tasker profile to simply force some apps under 60hz
https://forum.xda-developers.com/galaxy-s20/how-to/force-app-to-run-120hz-t4053133
I think adaptive refresh is not fully optimised
https://m.gsmarena.com/samsung_galaxy_note20_ultra_5g-review-2149p3.php
and that causes the bad battery drain. Since I've implemented the tasker routine battery now drains normally. Hopefully next firmware update fixes it.

When it switches back to 1080p its default is 60fps. In the top right corner of the app if you hit the 3 dots it has has an option to set default hz. Set it to 120hz.

Nice, but the goal with this is to force the resolution to change from 1080p to 1440p and vice-versa. The fps is to just reset 1080p back to 120hz automatically since it defaults to 60hz when switched back.

I haven't tried the 96hz personally, but I don't see why it wouldn't work as long as your in 1080p. I don't think there is an option for 96hz in the default refresh rate setting so it be per app.
You could set it and try the UFO FPS test to see if its actually 96hz.

Hi whats the correct way of setting up bixby routines because I set YouTube vanced to work with wqhd and in the stats for nerds it works perfectly
But when I exit YouTube it does go back to fhd but doesn't automatically swith on adaptive smoothing

Thats what you need the Dynamic Display app for. Bixby routines will only switch the resolution. You need to use both Bixby Routines and Dynamic Display in conjunction.
Its explained in the main post.

I can't make this work, each version I get the same result.
I have the Bixby Routine set up, which works flawlessly.
But once I exit back to system the display does drop to FHD but only at Standard (60Hz).
I have set the default Hz in the Dynamic Display to 120 Hz, and I have enabled both the WRITE_SECURE_SETTINGS and the Accessibility option for Dynamic Display but still it doesn't work.

General Smart screen refresh is not working properly

Hi there!
I have been doing checks, measuring the refresh rate in the 120Hz smart mode and I have noticed that most of the time it is at 120Hz and has only dropped to 60Hz using two applications, like YouTube or Skype for example. No adaptive frequency and it has never dropped below 60Hz. You can check this by downloading an app from the play store or from the developer options, where there is an option to measure the refresh rate in real time

not true

The LTPO control works at a layer lower than the OS, so the fps monitor won't show the true refresh of the screen.
It's supposed to reduce in any static scene but I have no way of confirming whether it does lower the refresh rate or not
As for the 1hz, it probably is only active for the always on display with he second hand

Franco Kernel manager and there go to live monitor > perfmon and enable perfmon floating window.

If you want to check true refresh rate for free but with root, check this path:
/sys/class/drm/card0/sde-crtc-0/measured_fps
You can make Tasker task to show and record real-time fps.
Display FPS app is BS.

Correct me if I'm wrong, but 1hz would only work when the phone isn't being touched. If an apk is running, it will stick to 60 or 120hz due to the animation. Maybe via ADB you might be able to pull some information?

How To Guide HOW TO CHANGE THE SCREEN REFRESH RATE OF THE POCO F3 TO 90HZ

If we want to increase the battery life a little more, we can lower the refresh rate of the screen from 120Hz to 90Hz, thus we will achieve extra savings without having to put the screen at 60Hz.
To achieve this, we download the SetEdit app from the Play Store.
Now we will do the following steps:
1.- We check that we have the screen at 120Hz.
2.- We open the SetEdit app, we look for the record "user_refresh_rate".
3.- Click on the record and edit it with the "Edit Value" option.
4.- We will get 120, we change that value to 90 and press “Save Changes”.
5.- We close the SetEdit app so that the changes are saved.
Now the screen will have a 90Hz refresh rate, we can check it with Display Checker, although there are other applications.
Greetings.

Hi, I have already set it by adb with the command (adb shell settings put system user_refresh_rate 90).
But with the last version 12.0.4.0, I have problems wtith AOD, the screen stays black sometimes and even if I unlock my phone with fingerprint I heard it 's ok but the screen stays black ! I must wait one minute till I can see something.
So I don't use it anymore.
Do you notice that ?

Yes, AOD don´t work but for me that´s no problem. Greetings.

Do you think we can set the framerate with tasker ?
So when it is locked, I will put 60, and restore the value when unlock ..

Honestly I don´t know, I don´t use Tasker, but if you use Tasker, try it. If Tasker works, tell us. Greetings.

Hi, I forgot to say you that the changes are reversible, if we want to put it back to 120Hz or 60Hz it is as simple as going in Settings to Screen and re-dialing 120 / 60Hz. Greetings.

Hi sipiral5, Does the setting still remain after rebooting the phone? Thanks...

Hello, no, it did not stay, you have to put it again. Greetings.

In Eu rom, this solution works very good

Tried this on Xiaomi.EU 12.5.3.0 today, everything working including AOD and Battery Saver returning to 90Hz after off.

Hello there. Thanks for sharing this topic. So I'm an Mi 10T Pro user. I wan't to put that refresh rate to 120. But in the options, there's 60, 90, 144Hz. But adaptivesync does support 120 depends on the app. So i tried this trick, but nothing has changed. I also tried to put it at 90 and still nothing happens. Do you have any suggestions? Thanks.

I needed to reboot the phone once done to get it working (on xiaomi.eu 12.6.16 (haven't tried on previous ones).
I also see that SetEdit app has access to some intrusive permissions by default. So uninstalled it right after 90Hz set.
Thanks !

Question 90Hz display frame rate on OnePlus 9pro

How to force 90hz instead of 120? AutoHz only has 120/60hz. May be ADB command or editing build.prop can help me? OxygenOS 11.2.9.9.
The fact is that, this phone drops display frame rate to 60hz, when throttling. I think, if it possible to enable 90hz display frame rate, it'll solve all problems

You can't, the screen only has 120hz and 60hz settings, just like the 8 Pro.
Maybe someone can develop an app or kernel that can do it, since the phone has variable refresh rate, but I wouldn't count on it. Changing those screen parameters is very difficult, if not impossible, iirc

AutoHz from playstore has this option but it's a paid app

On OOS12, settings put secure oplus_customize_screen_refresh_rate 1 enabled 90Hz auto.
Maybe
settings put system peak_refresh_rate 90.0

will work on OOS11.

No it doesn't, on 9, and 9Pro you can only get 60hz or 120hz no in-between.

Tried this in termux without any luck. Refresh rate stays at 120

I tried this too. Is there even the slightest chance of getting 90Hz by changing the kernel code?

Why do you care about 90 Hz in the first place? It's not like you're gonna save much battery if any since it'll be locked to 90 Hz if you manage to set it somehow and won't utilize the LTPO technology.

{Mod edit: Quoted post has been deleted}
The Hz counter in developer settings or any other 3rd party counter from play store etc won't show the actual frequency of a LTPO display, it just doesn't support LTPO as of now. You can measure it using a high fps camera as some people did, you can find these on YouTube.

There is only one reason. During a long game in PUBG mobile, the phone resets the screen refresh rate from 120hz to 60hz. Accordingly, the responsiveness of the touch and the fps itself falls. If I could forcibly set the screen to 90hz instead of 120, the phone would not get so hot and would not limit the performance of the processor

Question Refresh rate stuck on 120

Hi,
I have my phone set to high refresh rate and if I enable `Show refresh rate` in developer options I see it is stuck on 120. If I slowly scroll the settings activity I can see it going down to 60-40-30 but as soon as I let it on a stationary screen it's back to 120. It stays on 120 in other applications as well (except the few apps locked to 60 eg youtube, google photos).
I am aware that it is intended to stick to 120 under ~30% brightness but be able to go down as far as to 1 with full brightness
Things I observed/tried:
- when I reboot the device and I am fast enough I can turn on `show refresh rate` which fluctuates between 1-120 as intended only to stick to 120 in a few seconds
- I had it work normally before but I don't know what caused it, I could not get it back since reboot (I tried rebooting many times)
- if I reboot to safe mode it works in the 1-120 region normally while in the settings app, but once I leave it sticks to 120, even going back to settings it remains at 120
- the problem persists if I set up another user on the device (via multi-user)
listed every settings with refresh in it's name
min_refresh_rate=0
peak_refresh_rate=120.0
power_save_pre_refresh_state=3
power_save_screen_refresh_rate=1
oplus_customize_screen_refresh_rate=3
I think these are normal.
Do you know how I could get variable refresh rate back? Or is this the normal behaviour?

And I just found it: enabling 'Disable permission monitoring' in Dev options causes this behavior. disabling it stops the thing.
