[XS] Change device screen resolution, The Correct way?

I owned a Sony Xperia S lt26i.
it will lags constantly while playing some games, i think it is because of its high screen resolution. (correct me if i'm wrong)
If i want to change whole device screen resolution from 1280x720 to 960x540
I just need to change the lcd density/screen resolution at build.prop and change all apps to 960x540 compatible (included launcher/dialer) , then change the details of my model to Xperia P (which is a 960x540 resolution)
Is it this way will work?
any help is appreciate

seems not easy to get an answer ~.~

You cant change the resolution of the screen. The density is another story though.

He wants to change the screen of the application.
No need to be an asshole, you know what he means.

If you have CWM installed then make a backup. Then apply the changes you think will work. If it works then good if not restore the backup.

Q1:
CWM with locked bl will work as well? (i mean backup)
Q2:
changing density = changing resolution?
if 1280x720 change to 960x540, then
341.54 PPI (my PPI i think 340 if didn't rmb wrong) need to change to what value?
Edit: Checked, LCD density is 320, so what value i gonna to change to suit the 960x540?
Q3:
i tried to change before, but seems Launcher is not suitable for this resolution and those apps like subway surfers still is 1280x720 (define by the watching the FPS (2x~4x) ), so means i need details of my XS to XP then the apps need to re-download?
Thanks for reply

For unlocked bootloader, CWM backup works on latest version. I think version 4 is newest
I have no knowledge about resolution. Maybe check white paper, on Sony site, for the P for its specs.
After build.prop changes reinstall apps. Market should see changes.
Good luck

i see.
Extra:
LCD density increase = Screen resolution decrease = Performance increase = Visual quality decrease?
is it this statement correct?

You can't decrease or increase screen resolution. The number of pixels are a hardware thing. You can change DPI, but that won't have an effect on the performance, but on how big or small everything will be rendered on the screen.

Oh ya.. This is the answer i want :crying:
It won't increase performance then no point to change it
that means we can't play subway surfers with full fps.. (even lose a samsung galaxy s)
Question Solved.
Thanks everyone!

I hope you weren't using subway surfers as your lag test. I just went to the store to download it and every comment about it said that the app made the phone lag/laggy.
My kids play temple run, looks similar, and no lagging here
Edit: I just played both and I have no lag. Game played smoothly. Only played a couple minutes though

yeah, temple run is constant 60fps and never drop, asphalt 7 still ok, but not constantly smooth also
max temp for cpu is how much? i would like to set it higher to prevent cpu decrease while gaming :silly:

Lowering res to 1080p

Hello guys,
is there a way to lower screen res to 1080p by default (for system and everything running)?
Thank you

You can google "wm size" and "wm density", for 1080p you might as well set the dpi to 420. I don't recommend you do this on stock rom though.
If you think this can help you save battery life, it won't.
If you want performance, the gpu is strong enough for most apps that you probably won't notice any different between FHD or QHD. For 3D gaming, HTC's boost+ can lower the game resolution to 1080p.
Indeed, if you change the resolution and density, they can make some apps acting weird.

It doesn't open apps faster, but it can make the UI smoother (transitions/scrolling). This is entirely subjective of course, and then there's the variables of different rom/kernel combinations

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.

Lower screen resolution

Hi
I'm currently using redmi note 8 running a custom rom.
Is there a way to lower the screen resolution from 1080p to 720p?

You can do this with root via terminal apps. Not done this for a while but the command used to be wm size. So you would for example use the command, "wm size 720x1080".

I only find guides for other devices. How to change resolution I know, but I am not sure which settings will work. Usually I just carefully try, but I read that Changing Resolution and Dpi bricked some MIUI 11 Devices, so I am not sure, if I should do it. A bit more performance and battery would be great, but right know no money for a new phone, if somethings going wrong

I use this

Moto G Power Boost GPU Performance

Requirements: ADB Fastboot and Windows PC
Enable USB debugging in the developer opinions in settings and connect to USB using data cable.
In the search bar on Windows type CMD.
For this tutorial we will be using the Moto G7 Power screen resolution.
In CMD type adb shell wm size 720x1520 and adb shell wm density 319
To go back to stock just type adb shell wm size reset and adb shell wm density reset.
Go to display settings and keep the display on for 30 minutes before you tamper with the display settings or it could lead to a soft brick.
Download GPU Mark benchmark and you will notice it's much smoother and there's a 20ms difference in latency.
My scores:
GPU Mark
720x1520 957600
1080x2300 stock 592800
Geekbench Compute
Open CL: 366
Vulkan: 506 (beat the best score 501)
Original settings for G Power 1080x2300 and 319 DPI.
This should help apps open faster and the UI will feel more fluid.
Gamers will also benefit from increased fps in games like PUBG.
enjoy!

Has anyone else tried this?

You are lowering the display resolution is all that's happening here. Since there is less pixels to display it will be able to render faster in exchange for loss in visual fidelity (resolution).
It's like running a benchmark in 1080p then the same one in 720p. You can make things appear bigger or smaller using the DPI setting.
