[Q] Changing a device screen resolution (TOTALLY without any error/bug) - Android Q&A, Help & Troubleshooting

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) , then change the details of my model to Xperia P (which is a 960x540 resolution)
Is it my steps will work?
any help is appreciate :laugh:

[Q]Pixel Density and Games

Hey there dev's and users...sorry to bother...
i've noticed that SE xperia mini,mini pro,active,live with walkman have the same cpu/gpu/ram as xperia arc/ray/play but they have lower screen res...
sooo....
if you use a game which is built for arc/ray/play it would run on the lower res devices but some buttons/options wouldn't be able to be used because of the screen resolution...
is there any way to fix the apk of the game so it could be used in the lower res devices?
because those games aren't available for our devices normally...

Changing the display resolution (not DPI)

Is there a way to change the Display output resolution in Android?
I'm not talking about the screen density (DPI). I'm talking about the pixels.
The thing is I own an Acer Iconia A700 FullHD tablet but there is lag, especially on 3D games that forces the native screen resolution of 1920x1200.
So forcing the resolution from 1920x1200 down to 1280x800 would theoretically reduce those lags.
So it works with some games that comes with an option to change the resolution, but most games doesn't have an option, they simply run in 1920x1200 and lag really badly.
Is there a way to change the overall resolution down to 1280x800 ?
I know it MIGHT be possible but there could be a problem because the image has to get upscaled to the native display resolution.
And I don't know if the Tegra 3 comes with an hardware scaler.
So if the resolution gets changed, it might get upscaled and filtered (or not) OR just centered in a smaller image in the middle of the screen.
But either way.. Is it possible? if yes, how?
Thanks in advance.
[Q] Change Smartphone Display Resolution FHD 1080p to 720p via soft?
This is possible?
Currently many smartphones are already FHD, but what if we want to reduce to 720p to improve performance, it is possible via software? something like in windows, or is not possible unless you edit the kernel?
This an interesting topic.
In terminal:
su
wm size 800x1280
To reset back:
wm reset

[Q] HDMI scaling problem since 4.2?!

I have a Sony Xperia Tablet Z (1920x1200). With original 4.1.2 it would correctly scale the picture to 1920x1080 when connected to my TV with MHL/HDMI-adaptor. Since 4.2 and now with 4.3 update it will not change the resolution and displays a squeezed 1920x1200 picture on my TV. So the aspect ratio is corrupt, making wide faces etc. when watching photos or movies.
Sony says that it is Google's fault.
The Xperia Tablet Z has a hidden service menu where I can change the HDMI resolution but it is set as 1920x1080 as standard, and changing this to 720p does not correct the aspect ratio issue.
I have bought the app Screen Settings from Forbitel, and I have also tried other resolution changer apps, since I am rooted and have Busy box installed.
I am able to change resolution to 1920x1080, which displays correctly at my Tablet Z (it leaves 120 pixels unused =black bars at top and bottom) BUT when connected to my TV it will still only display a squeezed 1920x1200 picture on TV screen!
Why has Google removed the scaling from 4.2 when it was working perfect in 4.1.2?
Any information regarding this or ideas how to fix it would be much appriciated! Thanks!

Is it possible to change the rendering resolution of the Xperia Z Ultra to 720p?

I was wondering if it was possible to change the rendering resolution of the phone from 1080p down to 720p? But I still want to retain the scaling of things. The reason I want to scale it down is because I'm fine with 720p if it means I can push the processor to perform better on games (because it's rendering fewer pixels) and to save battery (smaller screen resolution would mean less stress on the processor = more battery saved).
Just to clarify, I'm not looking to change the DPI, I can use the App Settings xposed module for that. What I want is to lower the rendered resolution so that the processor doesn't have to spend more resources in displaying things.
