Changing the display resolution (not DPI) - Android Q&A, Help & Troubleshooting

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

is it possible to change resolution on my viewsonic tablet?

Hi All,
I currently own a viewsonic vpad 10s tablet. It's currently on 1024x600.. is it possible to have a software hack or other to change the resolution to 1280x like the xoom?
The short answer is no.
The longer answer is...kind of.

OK, and now the even longer answer.
There is no way to increase the resolution to 1280 x 800. Our display is an AU OPTRONICS B101AW06. Look it up on the net & you'll find max resolution is 1024 x 600. What BK553 is speaking about is a change in text DPI. You can see this in Windows where you can change the DPI. Manufacturers normally set the DPI to give the user the best readability but not necessarily the highest DPI. If you change the DPI, text & icons will become smaller (or larger depending on if you increase or decrease the DPI). To see what effect LCDDensity Changer may have, see the attached picture. Icons are smaller & text is smaller, giving the illusion of higher resolution. Notice how the backbround is the same while the text & icons are smaller.
Again, you can not change the resolution...videos, pictures etc will always displayed at a max resolution of 1024 x 600.
By the way, check this post http://forum.xda-developers.com/showthread.php?t=864338&highlight=lcd and you will see that atleast in Dec 2010 there used to be a field in build.prop that you could change to change the DPI. I looked for it in mine (I'm running Calkulin+Clemsyn Combo v6) and that field no longer appears.

I use blade and spare parts to tweak the dpi. don't think you can get up to 1280 with any software though.

[Q] Changing a device screen resolution (TOTALLY without any error/bug)

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:
bump~
bump is allowed?

[Q] Decrease Resolution for Gaming?

Hello Tablet Z community,
This is my first post in this devices forums since getting mine last week. It's a great device, love it, etc.
I've never owned an Android device with a screen resolution this high so I've yet to encounter this problem - some of my games (specifically the emulator PPSSPP) have relatively low framerates (compared to my less powerful Samsung P6810 @ 800x1280). I know with computers in particular it's trivially easy to change resolutions in games/the OS, especially to increase FPS but I've never seen a method to do this on Android and Google searches turn up people mentioning device resolution without changing them.
Does anyone know if it's possible to, ideally, force a different resolution for a particular application? A less than ideal solution would be a system wide change but I would be willing to endure temporarily to increase FPS.
Any advice and suggestions would be greatly appreciated
I would be interested to know about this, iv just loaded ppsspp however havent been able to play any of the playable games listed, I did see a few videos of the xperia z playing well, however that has the same resolution and specs.

This is very different, setting the DPI to a non-stock value just resizes the userspace, the resolution is fixed and unchangeable as the OP is thinking. Compared to a Windows PC where you can change the resolution, in Android you only have the ability to change the dpi, which states how large the pixel-to-screen size is. A smaller number indicates a smaller pixel-to-screen size, meaning the information shown on screen is sized for a laeger screen (making it smaller, since the screen is a fixed size). And a larger number has the reverse effect. Android UI guidelines set the optimal dpi for resolution vs. screen size, to mainain a similar experience across devices (similarly sized icons and fonts, etc). Again, this has nothing to do with adjusting the physical resolution of the device, which (to my knowledge) is not possible in Android.

Heh. Thanks for the schooling, but it was unnecessary, I didn't just fall off a turnip truck.
Thanks for the replies guys, at least now I know for sure..

Physical (capacitive) buttons not working after change resolution

Hi,
My device is ASUS ZD551KL running android M, stock rom, not rooted.
It display resolution native is 1920x1080, and 480dpi. With this resolution playing game a bit heavy, so i try to change display resolution and dpi. I did that using adb shell command to make resolution 1280x720 and 320dpi.
The problem is the physical (capacitive) buttons not working when i change the resolution (with dpi changed it works fine). So, anyone can help to get around this problem? With non rooted solution preferably.
Thx.

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.
