Success in disabling Temporal Dither - How to

randomboolean

I've tested the technique on the Lenovo M11 tablet, running the original Lenovo Android 15. The settings were applied successfully without any errors, though I believe the device didn't support HDR to begin with. I got supportedHdrTypes=[], so it didn’t make a difference in terms of eye strain. That said, the technical part definitely works on this tablet too.

Keep in mind this only covers HDR-related settings, which aren't available on all tablets. There are other settings that caught my interest. Since I experienced quite a bit of tension and eye strain from the tablet overall, I couldn't clearly tell if these had any positive impact. Still, I wanted to share this in case someone else wants to experiment and see if they notice any improvement.

If you're seeing these settings on Lenovo’s custom Android, you might see different ones on your device. Even if HDR doesn't appear available, try disabling the HDR settings anyway. It will generate the hdrcheck.txt file as the original poster mentioned, and you'll see which options are available for your specific Android version and tablet.

Thanks to OP for uncovering this. These are the settings I tested (there are many more):

enable_adaptive_tone_improvements_1

enable_adaptive_tone_improvements_2

display_color_enhance

color_enhancement_mode

display_scene_detection

development_render_effects

randomboolean hiee , even am facing issues with Lenovo tab m11? Does device has TD issues? Or flicker issue?

Can really read anything on this device

If you could help me with settings, would be really grateful to you.

You say that this only works on and above Android 14.

Does this mean there is no dithering in Androd 13 and below?

Intet

Reinhard62 No, I believe dithering was introduced around Android 11? But I'm not sure. It will work on android 13 and apparently even some android 12 builds, but only with Android 14 and above the setting will actually stick after restarting.

I want to thank you again for these wonderful instructions.

Thanks to you I dared to update my Motorola G54 5G from Android 13 to 15.

The G54 already has a pwm free display, so the elimination of dithering makes everything perfect. Now the display is a joy to look at!

I'm still not having any luck finding a device that this works on. Just tried the Razr+ 2025 today, and the cover screen still clearly dithers. Have we seen any additional methods that might work?

Here is a gif I made from a video I recorded. It's usually not quite as visible, this was an ESPECIALLY bad spot.

This is one of the most important threads. It should be right at the top.

With the method explained in the first post I could create the most perfect phone:

Moto G54 5G (with Android 15) has a LCD screen without pwm. Nevertheless, something didn't feel right and after half an hour my sight became blurry. It was the dithering which comes from Android.

Applying the instructiones in the first post the phone now is completely flicker free. I can look at the display the whole day and it doesn't stress my eyes more than looking at a piece of paper.

Reinhard62 You Moto G54 was on Android 15 before this update? I thought you were keeping it at Android 13?

This seems to have worked on my Xiaomi 14T Pro. Thanks a lot!

I kept it on android 13 before I knew these instructions. (Because I thought there is less dithering in Android 13.)

But since the settings are only kept permanently in Android 14 and above (i.e. after a restart) I updated to Android 15, and then applied the instructions in post 1.

Everything is perfect now. No pwm, no dithering. Doesn't matter whether it's a webpage or video or whatsoever.

If you reset it to factory settings, I suppose the "no dithering settings" are gone. But why would you want to do that???

K-Moss

Intet The dithering this removes is noticeable even for office work, or mainly for video? Also in a worst case can one reset the phone to factory settings and remove all these configurations?

K-Moss

So one needs Windows to apply the instructions? Won't work with only Linux?

Jack

K-Moss Adb runs perfectly on Linux as well.

Jack Says Windows here and the exe won't run on Linux: https://www.jottacloud.com/s/138d7ab235585ad427883e2f06cb0ecd4b6/thumbs

K-Moss adb is a cross platform utility.

I think I figured it out. So after I apply these steps, can I factory reset the phone if need be to bring it back to manufacturer settings?

Also, aren't these dithering features used only for video? Do you really notice an improvement when viewing basic web pages?

K-Moss

Reinhard62 On my Moto I notice a clear increase in eye comfort when I turn on Bedtime Mode. This is monochrome / black and white mode. Does that indicate I am having some strain from dithering?

"If you reset it to factory settings, I suppose the "no dithering settings" are gone. But why would you want to do that???"

This is just because I want to know if for whatever reason I want to go back to default settings that I can do so through a simple Factory Reset.

Also, do you have any evidence there is more dithering in Android 14, or is that pure speculation based on anecdotal experience?

StaticLCD

Reinhard62 how did you confirm no PWM? It is actually DC dimmed? That's so rare these days.

Reinhard62

K-Moss

When I updated from Android 13 to 14 the dithering seemed to get worse.

Now, before asking another 100 questions, just apply the settings!!!

I assure you, it's impossible that it gets worse, it can only get better. Just DO it.

Can anyone here start recording their phones with a Carson Microflip using 240 fps or higher slow motion? It would be at least interesting to see whether dithering is actually changing in terms of temporal frames and if it engages on different colors from OS to OS.

K-Moss

Reinhard62 "For some, maybe it helps when you disable it, for others, it actually makes it worse when you disable it."

I don't know if it will get worse when I run these commands, so I need to know if I can revert them after if for whatever reason I wish to. Does a Factory Reset successfully revert whatever this does?

There's not enough feedback from others vouching for the success of this. Works for you, Reinhard62, but not many others are saying it works for them.

Reinhard62

K-Moss

Whoever said that disabling dithering would make things worse, obviously didn't know what he was talking about.

Of course, the display will be much more eye friendly without the dithering.

And yes, a factory reset should revert the settings.

But this is the last thing I write in this respect.

You, K-Moss, will probably be asking another 50 questions for months to come. And you will never do anything.

But enough. I'm out of here.
