[Q] Best way to change screen resolution?

Hey, everyone! I'm looking for the best way to change the resolution of the G3. I used an app that supposedly does it, and it did, but it bugged out every boot to where it would go back from 1080 to 2K, though it would think it's 1080. I know 2K is awesome, but not only can you just about not notice the difference, but game performance are GREATLY increased!! Battery life may be much more improved as well due to using less GPU power. I had frame drops on PPSSPP playing Monster Hunter in 2K but at 1080, it was always locked at 30fps. Heroes of Order & Chaos I think had worse frame drops but I hadn't gotten the chance to try it yet. Can I change the actual screen resolution, and not the DPI alone, through the build.prop file or something?

I tried that app, and used the G2 preset. It made the status bar look funny (the icons became too big for the bar) and I didn't notice any performance improvements.

That, in a nutshell, is what you get when you artificially "lower the resolution"

Switching Display Res from WQHD - FHD

Hey guys,
So just wondering has anyone noticed and pros / cons when switching the display resolution from WQHD ( 2560 x 1440) to HHD (1920 x 1080)?
Ive switched to it back and forth several times, and so far I really cant see any difference. The screen quality / crispness seems to be the same. Also I noticed that when i have FHD selected the device obviously seems to run a little faster / snappier.
Incase you don't know what I'm referring to its in Settings>Display>Screen Resolution.

Hmm the only place I can change that is by turning on a power saving mode, I don't see any screen resolution in the settings otherwise (on Canadian N930W8).

Thats strange I have it as a stock option in settings...

I tried it once and didnt like how the LCD density increases significantly. It also doesnt play nice when setting a custom LCD density via a root app or through adb.
I've noticed no improvements with quality, performance, and even battery life. Setting the res to anything but WQHD actually somehow drains more battery and causes performance issues.
To ellaborate on the tricky LCD density issues, I thought I could set the res to 720p and the LCD density to my usual (420 down from stock 560), but having the density to 420 on WQHD and then changing it to 720p essentially erases the set density, and then things get a little funky when trying to re-change the density. Doing so causes some weird glitches since the density of 420 on 720p is based on the resolution, so it actually makes the density much bigger compared to stock density on 720p, and then setting the density to the proportionate number based on calculating the difference causes the entire Ui to seize up and crash. The same effect you would get where if you set the density below 300.

Ok thanks for the great answer! Guess ill stick to WQHD! Just thought it might offer some benefits.

been testing this and found that it does not get warm when switched down
and to the eye same amazing screen

Sorry, but my findings are almost the opposite, I even made a thread in discussion forum to regard the change to FHD to other users.
FOR ME, switching to FHD has improved the responsiveness of the UI (graceui) considerably, and I do not see the "LCD density increase" (btw.: what should that be? i guess DPI?? then switching to FHD would be a DEcrease...)
Also, I'm almost sure that this must lead to battery improvement too. simple because cpu und gpu have less work to do calculating the lesser amount of screen-pixels to draw! This might be slight, but should be there!
The other problems you mention are because you are playing around with density mods, are you using xposed? I use the lower FHD resolution now for a week, and I do not have ANY problem with it!!! And trust me, I use this phone the whole day long and have many programs and communication tools installed.
everything works as it should!

This was the case both on root/unroot using standard adb shell wm debsity xxx and in-settings res.

Can a Mi10t lite downgrade to 90hz?

Since I’m actually afraid of consuming the battery life and personally don’t need 120hz, is there a way to downgrade it to 90hz?
And if it isn’t possible via settings, is there a DBTO image that can allow that?
thanks

I don't think it's possible (yet) but It's adaptive sync so it will not run 120hz at all time, it will run at the supported hz's of: 30Hz/48Hz/50Hz/60Hz/90Hz/120Hz
For example on the home screen and settings it will run at 50hz (according to my test) when you not scroll, only 120hz when you scroll or touch.
Most games locked to 30/60fps and it will not run at 120hz there of course.

I know, but even with adaptive sync I don't think this phone will get to 7 hours of usage with display on

My phone with normal usage (chrome, youtube, instagram, some light games) gets 8-9 hours on screen with 120hz (adaptive sync).

Question How to Force All the apps to get 120Hz?

Hello sfu,
I alr set my display to 120Hz, but does it mean I am getting 120Hz on all my settings ??
If not, how do I force all the apps to get 120HZ?
Thank You.

Isn't it always 120Hz? Check with the app that display refresh rate. But the last time I checked, everytime it was 118-120Hz.

some apps revert it back to 60hz, like youtube, google photos, netflix. Recents apps page is 90hz

You need to delete battery app data.You will have yt and all aps on 120hz but after some time it reverts on 60hz and you need to delete it again.

That's troublesome though, is there any other way to make it permanent to 120Hz ???
Why it keep on reverts to 60hz?

That is the question for Poco.

I believe the idea is to keep battery usage to a minimum... Apps that don't natively make use of the 120Hz are switched back to 60Hz in favor or battery life. In short 120Hz is actually adaptive refresh rate.

I thought it was an adaptative screen freqency rate but actually, we only have the option to set to 60Hz or 120Hz. Only. Or did I miss something ?

According to the GSMarena review, F3 has variable refresh rate, it will automatically change between 60,90 and 120HZ. This guide will lock it on 90hz

So why in settings I only see 60Hz or 120Hz and nothing about 'switching' 'variable' etc ? :s

Just put it on high (120hz). It will automatically reduce to 90hz or 60hz depends on what shown on the screen and how you interact with the screen.
For example, when you're watching a website, reading text, it will automatically put back on 60hz. And when you touch the screen (for example, to scroll the website) it push back on 120hz

Question Experiencing stuttering and performance issues

Hello,
I've had this phone for a week and while there are certain things I love about it (the fingerprint scanner and the cameras are amazing as you all know), I've been very disappointed with the phone's performance. In my case, the phone has a lot of hiccups and stuttering while browsing through menus and in particular, the screen has a delay and slows down if you're opening menus while you have youtube or the camera app or any kind of media open. If I had to describe it, it's as if the display slows to less than 60 hz while trying to play animations, with everything becoming slow and jagged and laggy, although I have set it permanently to 120 hz. The smoothness just isn't there and I noticed that if I open a youtube video and hit stop, the phone becomes decently smooth in menus, but as soon as I hit play, it slows down right away.
It's particularly strange since the phone does not overheat as I've read it does for some people, yet it has those performance issues even while playing videos at a lower resolution. Sometimes I get the same delay and lag even in basic apps such as messenger while typing. The scores I get in benchmark apps are the same I see in reviews, yet in real-world use, it's less smooth than a mid-range, not to mention other flagships. Hell, I still have my Oneplus 7 pro and that's way smoother and you don't even notice when you have youtube in the background.
Did anyone else experience that? Returning the phone would be quite a big hassle at this point, so I'm hoping there's something else I could do. I've tried all kinds of things like resetting the phone, allowing full access to battery for most apps and other similar measures, but I'm willing to try more.
Thanks.

Go to Developer settings > Running services
Running services is basically a task manager for Android
You can also terminate tasks in there
First active Developer settings. In case you don't already know.
Go-to Settings
Scroll down to about phone
In about phone go to build number and tap it multiple times until it says "you're now a developer!"
Go to outside of about phone and Developer settings will be below About Phone.

Hey, thanks for the reply.
Everything seems to be fine in terms of resource usage, or at least nothing seems to use a ton of resources.

You can click on the settings (three dots) on the top right corner and click "Show cached Processes", maybe the system is not getting rid of old cache data.

Okay, so I've discovered the main issue, but nothing that works to fix it yet. Thanks to your tip of using developer options, I activated the show refresh rate option and sure enough, it drops to 60 hz or lower in a lot of apps, despite me having it set at 120 hz permanently.
Now I know youtube and a lot of apps only support 60 hz, but the strange thing is that the entire screen drops to 60hz while using them. For example, if I check my notifcations or do anything else with the dropdown menu, the display just slows down in menus. As a reference, whenever I used youtube on my old One Plus 7 pro, the dropdown menu was always smooth and set at 90hz even while running youtube or other apps.
I've tried some apps like SmartHerz, Setedit and forcing 120 hz through ADB commands on the Vivo X80 pro, but I've had no luck yet. At least I know what to focus on, thank you for the tips.

Well at least you were able to narrow down the issue, hope it's easily fixable because the X80 Pro isn't a cheap android device, I certainly hoped it would come with good software.

Vivo implantation of LTPO panel seems to be bad and very laggy.
For reference, mine ROG6 is so much faster than the x80 pro it's not funny, and ALL the apps staying at my chosen refresh rate(unless it's hard coded to use a fixed value).
I'm on A13 beta atm, and i hope they'll fix it asap.

Yeah, it's such a shame to see this amazing hardware being held back by its software.

Any luck forcing refresh rate to 120 Hz ? I tried different options too but none of them work. Due to LTPO , the refresh rate keeps dropping to 24 Hz when there is no touch which is expected IF smart switch is selected. However since they have given an option to CHOOSE 120 Hz in settings then it should be forced even if it means more battery consumption. Currently that setting has little meaning.

No luck here, the option really is pointless and none of the tools that work to force the screen refresh rate for other phones work for Vivo at least from what I've tried. It's even stranger that the entire screen drops to 60 Hz throughout the menus as well, my One Plus 7 Pro kept the scrolling and the drop-down menu smooth at 90 Hz even while running apps like YouTube, but the X80 Pro just slows everything down.

Yes , if a Youtube video is playing then the Menu (Settings) screen drops 60 Hz. Otherwise its at 120 Hz if you are scrolling etc.

What's strange is that people are able to force OnePlus 10 Pro displays to 120 Hz refresh rate from what I've seen using apps like Setedit or ADB commands and that phone has an LTPO 2 screen. Not sure whether it's the LTPO 3 that makes those not work for X80 Pro or whether it's something from Vivo themselves.

It is likely Vivo's implementation. Afterall Its a variable refresh rate and Vivo can force it to 120 Hz if a setting is provided.

Hey guys I found a solution, kind of. Use brightness below a certain level, ltpo won't activate
I'm using around 30 percent, I checked using show refresh rate from dev options. If it's around 30 it stays 120 no matter which app you open. Also setting peak refresh rate to 1 in setedit helps. Good luck. I'll update once I find an option to stop ltpo from working using setedit or something. Plz reply if you know any better solution. Cheerio!
