How To Guide [No root] Disply always in 4k mode

[MK73DS]

Phone became a bit laggy no?

I don't notice any lag, everything is still smooth at 120fps. Maybe in some games? I don't play games so I don't know.
However, it uses a bit more battery, so be careful. If you have a rooted phone, you can have a script which switches between 1080p and 1644p. If you have termux (+ widgets) and sudo installed, you can even put it as a button on the power menu ! (Quick 4k toogle)

Note : I'm not an experienced user, my script may be really unoptimized or ugly, but it works!

#!/bin/bash

if [ "$(sudo wm size | grep Override | cut -d "x" -f 2)" == "3840" ]
then
 sudo wm size reset
 sudo wm density reset
else
 sudo wm size 1644x3840
 sudo wm density 630
fi

Hello, very intersting !
Thx

Thanks for this. Very nice that I can use what I paid for!
One question though: Why set the desity to 630? Quick googling said the density is 643 and according to Google 640 is the goto number:
https://developer.android.com/training/multiscreen/screendensities (go to table 1, a bit above the middle).

With my own eye I cannot see differences between those two settings and maybe there are none, so out of curiosity, why 630?

You will see a difference in keyboard, try it.
If you can't reproduce it I can show you.

That's a damn shame - would it be easy to make a tasker routine or something to issue those commands automatically when an app is launched?

If you're still wondering, here.

Tweak density to your liking.
Lores
Default wm = 420, small = 356 or ~85%.
Hires
Default wm = 640, small = 542 or ~85%
(You can change the wm density to the latter values if you want, I changed them.

Obviously requires root.

I'll also throw in some tasker refresh rate changes.

Very useful for when the device is mounted and I'm driving.

I don't use Gboard and I have no problem with my keyboard, so I'm setting 640.

I have some lag on the smileys in the messages, but I'll take it for now. Want to change this app as well anyway.

IMPORTANT: This no longer works after the update to Android 12. 'wm size' resets itself to default immediately after you change it. If you know (or at least have an idea) of a possible fix - please reply, so far I'm clueless.

If you have already updated like me you can run 'wm density reset' so your phone looks normal again.

Thanks for the heads up. Will postpone the update for now.

Yeah that update sucks. Basically it makes display worse than average 1080p phones (upscaled 1080p looks worse than native 1080p).

dumpsys display | grep mBaseDisplayInfo

mBaseDisplayInfo=DisplayInfo{"Built-in Screen", displayId 0", displayGroupId 0, FLAG_SECURE, FLAG_SUPPORTS_PROTECTED_BUFFERS, FLAG_TRUSTED, real 1096 x 2560, largest app 1096 x 2560, smallest app 1096 x 2560, appVsyncOff 1000000, presDeadline 10333333, mode 4, defaultMode 1, modes
[
{id=1, width=1096, height=2560, fps=60.000004, alternativeRefreshRates=[120.00001]},
{id=2, width=1644, height=3840, fps=120.00001, alternativeRefreshRates=[60.000004]},
{id=3, width=1644, height=3840, fps=60.000004, alternativeRefreshRates=[120.00001]},
{id=4, width=1096, height=2560, fps=120.00001, alternativeRefreshRates=[60.000004]}
]

I've launched different apps (built-in video player is supposed to run at native resolution?) and it always stays at mode 4 (if I set 60 hz in settings then always mode 1).

Is there any way to switch display mode via adb command?

wm size

also always returns 1096x2560 regardless of app.

Playing with wm size I've noticed that it tries to keep aspect ratio while decreasing entered resolution to fit into what it believes to be "real" (1096x2560). So 1644x3840 becomes 1096x2560, 2000x1000 becomes 1096x548, 2000x2000 becomes 1096x1096, 2000x4000 becomes 1096x2192... Yet 2000x8000 becomes 1096x2805 (probably caps 8000 to 5120 before resize) and 1096x3840 stays 1096x3840 (but looks really blurry).

Also found "display_size_forced" in settings - global (settings put global display_size_forced) it accepts 1644x3840 but doesn't seem to do anything...

Just a thought - the way Creator Mode is worded in Android 11 suggests that it opens 4k mode for any app you add that turns on Creator Mode. Could someone confirm if this is true of not?

 

[UsernameNotRecognized]

A poke to ask about Android 12 and 4k any more info?
I'm hesitant to upgrade if Android 12 does not support 4k mode...

 

[BlazingKahn35]

Doesn't work on Android 12

I run creators mode all the time (as I did on Android 11) and it's not in 4k

 

[APTXDAVE]

Chiming in my 2cents here. Also confirming it does not work on Android 12.

So far Android 12 is proving a real pain is the ass.

My advice - dont bother - stay on 11 until changes are made or workarounds are resolved

[UsernameNotRecognized]

Meh, I decided that I didn't care enough. If someone can fix this down the road that's great, but for now I'd prefer having Android 12.

I'm more annoyed that google moved the device controls to the quick settings.
Why

 

[APTXDAVE]

Im still keen for a fix if someone comes across it. A12 has been underwhelming

 

[MK73DS]

Any update after 6 months? I'm still on A11, has this issue been fixed?

I'm on Pixel Experience GSI ROM and you can force 4k in either 60 or 120hz in Settings//Phh Settings//Misc. Looks wild but not really usable and certainly not worth the battery drain. Would be nice to have a quick setting for this.

To clarify, "wild" just means everything looks very small but I didn't notice any difference in the quality of the image.

This is super simple to do. You can scroll up for my findings and tasker share. Tune it to your likings and connect it to a quick-setting tile and voila.

What Pe+ are you using btw?
This one?

I am using Ponce's PE+ v414 (June security patch). Very cool that you have one customized for this phone. What's custom about it and do you think you'll make new ones (assuming it's you who built it).

Also, awesome that you created a tasker routine for resolution switching. I will definitely check it out. I admit I didn't read this whole thread, I just noticed the feature on PE+ and that I'd chime in.

Oh no, I didn't make those. These are the ones I'm aware off but never installed. The last update is a bit old (may). and the lack of instructions...

So you're using a GSI?

Maybe I should look in GSI's instead, being so common support is much better. Did you flash A11 firmware or is this no longer necessary? Or maybe different, could you link me to the instructions you used?
