Summary
Pixel 6 Pro goes down to 10 Hz as expected when idle in normal lighting
In low ambient light & low brightness for darker content, refresh rate only goes down to 60 Hz
Pixel 6 Pro PWM frequency is 360 Hz, lowering down to 120 Hz at <20% system brightness
AOD goes down to 10 Hz as expected
Battery Saver/Smooth Display disabled does not go down to 10 Hz, stays at 60 Hz
Watching 24fps/30fps movies/videos does not lower refresh rate down to 24/30 Hz, stays at 60 Hz
The important bits
Some people have (mistakenly) used Android's refresh rate indicator within the Developer Options to come to the conclusion that the 6 Pro's variable refresh rate only goes down to 60 Hz, because that's what the indicator shows when the screen is idle. However, Android's refresh rate indicator does not show the OLED panel's lowest operating refresh rate, due in part by how its VRR is implemented. The Pixel 6 Pro's Samsung Display panel has a variable refresh rate mechanism that operates at a much lower level, within the display driver, and not exposed to the Android user-space.

Samsung's VRR implementation is not the same as those found in typical gaming monitors which can target any arbitrary refresh rate. The VRR found in Samsung's HOP ("LTPO") panels still work by switching between discrete refresh rate modes, like older implementations, but the new panels now incorporate a low frequency drive (LFD) mechanism which operates the OLED driving rate at a fraction of the current refresh rate mode. As an example, a 10 Hz driving refresh rate is achievable by operating the panel at 60 Hz but skipping re-drives for 5 out of every 6 refresh intervals if the frames are the same.

And from (#1), we finally find some solid proof that there is a 10 Hz fundamental driving frequency in the Pixel 6 Pro display when screen content is idle, despite the Android refresh rate indicator reporting 60 Hz.
Along with it, we find two other fundamental frequencies at 120 Hz and 360 Hz. The peak at 360 Hz is almost certainly the PWM frequency, and 120 Hz is the fundamental refresh frequency from which the 10 Hz LFD is employed from.

I also tested if the Always-On Display went down to 10 Hz (#5), and I can confirm that it does. It's driven at a 120 Hz PWM freq. and a 60 Hz fundamental refresh, employing LFD down to 10 Hz.

Themes / Apps / Mods [App]Galaxy Max Hz (Refresh Rate Mods, Screen-off Mods and More)

About this app:
Refresh Rate Control: Easily control the max refresh rate (Hz) of android devices with multiple refresh rates (e.g. note20 ultra, s20/S20+/S20Ultra, z fold 2, s21/s21+/s21Ultra, tab S7/S7+). This app can limit max refresh rate to 96hz (or any available refresh rate) on supported smartphones - you can save power with negligible difference on smoothness. Use either the in-app toggle or quick settings tile - ADB setup or Root NOT needed.
Switch to High: Option to use High(Fixed) motion smoothness mode on Samsung devices with native Adaptive motion smoothness***
Current Samsung smartphones natively supporting adaptive refresh rates:
Galaxy Note 20 Ultra
Galaxy Z Fold 2
Galaxy S21, S21+, S21 Ultra
Refresh Rate Monitor: Observe how multiple refresh rates work on your device. Use either the in-app toggle or quick settings tile
Quick Resolution Switcher: Easily switch to any supported resolutions using the included quick setting tile***
Quick High/Adaptive on Power Saving Mode: Easily switch to high or adaptive motion smoothness mode (from Standard) even on power saving mode on supported Samsung smartphones.***
Force to Lowest Hz: Force lowest refresh rate on screen-off/AOD. This overrides Samsung's strange stock behavior which sets the refresh rate to the highest on screen off (update: it is now at 60hz since oneui3.0) - to improve standby power consumption a bit - ADB setup or Root NOT needed.
Auto apply power saving mode during screen-off***
Tasker plugin support: Automate GMH settings using Tasker plugin support. Supported actions/variables: Max Refresh Rate, Keep Motion Smoothness on PSM, Motion Smoothness Mode, Quick-doze Mod, Change Screen Resolution.
Ad-Free Exclusive Features:​
Keep motion smoothness when power saving mode is enabled - either manually or by the system/adaptive power saving***
Adaptive refresh rate mod: Experimental adaptive refresh rate mod for devices supporting multiple refresh rates but do not have the native Adaptive motion smoothness (e.g. S20 series, S20FE, TabS7/S7+, A52, A72)***
Quick-doze mod: Quick doze mode during screen-off to improve standby power consumption***
Set minimum refresh rate for adaptive mode to 60hz or lower (if available)***
Resolution switcher filter: Filter what screen resolutions to include for the resolution switcher QS tile.
Statusbar net speed indicator
7-day Ad-Free Trial is available. Just click "Activate Ad-free" button and activate free trial when prompted.
***these marked features require one-time ADB setup (this is not root)

Isn't it possible to get the screen damaged/worn out, when its switching the refresh basically every couple of seconds?

I don't think so as long as it's switching only between supported refresh rates.

v7.13
Anti-flicker: added minimum brightness threshold for Adaptive mod similar to the native one. When the device's display brightness falls below the set minimum brightness threshold, adaptive mod will pause and will resume once the brightness increases again above the threshold. This is for devices who are experiencing flickers when refresh rate switches at certain low brightness level.Stability and bug fixes

Thanks for your work, gonna test with my A72 as soon as it arrives

Fixed bugs on OneUi4.0: brightness threshold for adaptive mod bug, netspeed indicator bug
Fixed bug on minimum hz tile and minimum hz tile tasker command
Minor layout and tile improvements
Auto dim refresh rate overlay when not changing after few seconds
Fixed crashes on netspeed indicator
v7.14.17
Workaround for auto sensors off for OneUI4.0. Prior method was already blocked in A12.
Experimental workaround: enabling High/Adaptive on PSM on OneUI4.0 (not working on some models)
Fixed: setting min hertz for adaptive (%lhz) using Tasker not working

Question Downscale screen refresh rate

Hello, can we downscale refresh rate to 90hz to save battery? I dont notice 90 120 diff anyway haha

Great app thank you

Question 90 Hz on POCO F3?

There are two options in display, 60 Hz & 120 Hz. Can I run my display with 90 Hz refresh rate? If so, how?
Use SetEdit app from Play Store!
as far as I know in most kernel is disabled because it causes color shift or graphical glitches

Question Adaptive refresh rate analysed.

Tested the feature by enabling refresh rate indicator from Developer Options on One UI 4.1 Galaxy S22
It ranges from 24 - 120Hz rather than 48 - 120Hz
It dips from 120 to 24 after 1 second of inactivity
30 fps YouTube videos play at 30Hz but switches to 60Hz if speed is increased to 1.25x, 1.5x, 1.75x, 2x.
60 fps YouTube videos VidMate Mobdro play at 60Hz but switches to 120Hz if speed is increased to 1.25x, 1.5x, 1.75x, 2x.
Google Maps is stuck with 24 - 60Hz
Overlays like timers keeps it at 120Hz all the time.
Picture in picture YouTube follows the same as in the YouTube app.
Standard mode puts screen at 60Hz at all times.
From above examples, the display supports 24, 30, 60, 120 Hz refresh rates and not anything in between.

Any possibility to change *default* refresh rate?

Dear community,
I have set the refresh rate of my fire TV Cube 2 to adaptive. This works fine with applications that support it. Most of the content I watch is 50 hertz.
My issue is that Amazon shows apps and also the interface at 60 hertz default, unless the app itself changes the refresh rate. This causes me many unecessary refresh rate changes (black screen for 2 seconds), and many apps that have 50 Hertz content are show at 60 Hertz because they don't actively change the refresh rate.
I want to keep adaptive refresh rates, but I want the default rate to be 50 Hertz in stead of 60. Is there a way to accomplish this?
