Not sure if this is the correct forum, so please move it if need be
I am looking to change the resolution of a tablet, but so it is persitent (I am currently in a position to change the firmware, so maybe a build prop setting or init.rc?)
I can change the resolution using "am display-size widthxheight" but this does not persist through a reboot.
Is there a way to set it at firmware level?
I have tried various DPI settings, but I know it must be a resolution change, as I need to be able ot set it specifically to 1280x720.
Not sure what the original resolution is, but changing the DPI lower or higher does not change the fact I cannot view a 1280x720 image, at 100%, without scrolling.
Might it be the case I need to make a system app to run the "am display-size" command on boot?

its not recommended to change your resolution, i have bricked my galaxy tab before and was luckily able to recover it. what device do you have? hopefully its a first party like samsung otherwise Chinese tablets you shouldn't mess with them, the chip-set is not open source so its easy to brick.
helped

Hi everyone
So, I have this Android Tablet called the Haipad M701 which runs on Android 2.1
By default the icons and everything are HUGE, doesn't look too good So, I rooted the device and found a density setting which by default was at 240. I changed it to different values between 160 to 240 and with smaller values it looks very nice
BUT at any value other than the default 240, almost ALL apps and games are no longer in fullscreen
Does anybody know if there might be a fix for that?
Thanks
wow... not a reply since sept... not sure if you get it fixed or not.
one step you can try is to turn off the compatibility mode in your tablet.
this should fill up the whole screen in most apps except some apps that written specifically for small screen phone without adding large screen display mode in it.
halo
i don't see so well and the Resolution in the one s is to high to me
i raise the DPI Through rom toolbox to 260
but i get some error of the system ui "Unfortunately system UI has stopped"
for example when i enter to "recent up" i got this erorr and i can't enter there....
there is a way to fix it ??
thanks
If I'm not totally wrong raising the resolution will result in smaller letters. You should lower it instead. So please try it.
And you can change letter size within settings -> display & gestures -> font size. By default it is medium, so you can change to large or extra large.
At least under accessibility there is an option named TalkBack, which will activate a spoken feedback to what you touch, choose or activate. I hope your ability to see is not that bad!

I just checked that out.
What's with the notification about it "collecting" info? Collecting it where? And what? I didn't go any futher.....
Tomney,
I am not sure if this will actually work but if you have root you can edit your build.prop file. In that file there is a line that refers to ro.sf.lcd_density. By adjusting that number up or down you can change the dpi of the screen. Now that does not necessarily mean that all of your apps or even the Sense UI will work correctly, but it might be worth a try.
If you want to easily do this I would download the BuildProp Editor app from the market.
Haven't tried it on this phone, but at least on every sense Rom I've used for the hero changing LCD density has always messed up everything. One of the reasons I allways used aosp

as i said i did it with romtoolbox. it is the same , i raise the dpi to 260....
it makes some problems with system ui and i got some errors
i now replace the rom to miui and the dpi change doesn't Affects the system ui
dpi change can be on a rom without htc sense ui and i think even regular ice !
but..... now there is some problem with the market because Resolution Compatibility i think... there is some app i can't download .....
for now i need to come back to 240 dpi for download some apps and its Annoying
maybe if could change the Resolution to Exactly 800\480 i wouldn't get the market-app-Compatibility issue but i dont know how... maybe someone know how to do it?
my vision isn't so bad and i know the regular options aka font enlarger Etc ...
dpi change is the best choice for me .
Hi guys. Lets say I have a game or app and it lags cause of 1080p. (DO NOT answer like: This is not the resolution problem, because sometimes it is). Or just app is not supported by full HD. Anyway. Can I change the resolution for 1280x800 (Popular and from normal Transformer)? Does simply DPI change work? What to set? Please tell me. Just for the situation with 1280x800, I want ALL apps etc to run in this resolution. Will it lag anyway?
Sorry for my English.

Actually this is a pretty good question. Some games can't really be displayed in full HD because it just requires much better hardware than is in our devices. Lowering the resolution would probably be very helpful in improving the frame rate and consequently the game play.

I'd like to know an answer to this too. Is there a simple way to do this, such as installing an app from the Play Store?
perhaps paranoid android can help?

have not tried it myself.
I don't know of any app or setting that does what you want.
changing the dpi will do nothing to change the resolution. all that does is tell the OS the physical size of the pixels on the screen in an attempt to keep UI elements the same size across varying dpi screens.
for example, if you take an icon and display it on a regular screen and an hdpi screen with a straight 1:1 pixel mapping, it will appear much smaller on the hdpi screen. but if you tell the OS what the pixel density of each screen is, it then has a reference point and can then enlarge or shrink the icon so that it appears to be roughly the same physical size on both screens.
this is why lowering the dpi setting on your device shrinks everything. the OS thinks the pixels of the display are much larger than they are and shrinks the images to make them appear the intended size.
to change the display resolution, you'd first need a display driver that supports the lower resolutions, which we seem to have since we can output at 720p over hdmi. then you need a screen that will upscale lower resolutions to fullscreen (because you really don't want to play in a tiny 1280x720 window do you?) when non-native input (something other than 1920x1200) is received. i'm not sure if the display in the infinity is built to do that. they may have designed it thinking they will never run it at anything other than native resolution and left it at that.
who said anything about dpi?
Transformer TF300 update on TF700
Happily we have previous Transformers with almost the same hardware and lower screen resolution. Do I have FULL HD installing this (UP) ? I guess gaming on tablet with lower resolution is not possible, but maybe I can downscale the graphics with CHAINFIRE 3D. This is really cool feature. I think we all need it (now and in future). 1280x800 is acceptable res, and some games just won't work on FULL HD.

As the title says, you can use the adb wm size command to change the resolution, higher.
On most phones the resolution shipped is the highest available.
The RM3&3S ship stock 1080p but easily go up much higher.
Personally i recommend 1440x3120
wm size 1440x3120
In an su terminal or adb by pc.
This brings the display up to current phones resolution! (2k)
Enjoy!
As for performance and battery life, there is no noticeable NEGATIVE impact. However, when screen recording or streaming your screen, it can lag if your connection cant support the higher resolution. Native screen recording should be unaffected.

wow nice
anyone has tested this ?
I have downloaded the DevCheck app and under HARDWARE tab > Graphics > Resolution, it is shown as 2340 x 1080. Does it mean that on adb I have to type wm size 3120x1440 instead ?
Thank you

I have tried changing the resolution yes the screen changed to a smaller icon etc but the problem is the below area is not responding to touch for example, the soft button; back, home and app manager does not work when touched.
On mine

On mine it works without issue at all and I can touch all the way up to 5k no problem, can you tell me your device model and rom?
Not to be rude or offend you but it is 100% user error on your side, the resolutions are accepted, and tested on A11 and A10 multiple devices. Also the icons smaller and all that is just based on DPI, resolution is the resolving power.

No, use 1440x3120 it matters what order the numbers are in.
Thankyou
Thank you. For the display to work properly, you also need to change the pixel density. We enter three commands in adb:
wm size 1440x3120
wm density 640
reboot
Increased clarity even in games! See screenshots...

I played around with this screen resolution and returned to standard resolution!
So i really like the DPI at 200, it means I can see more than 4 lines of a text message and dont need to scroll for days to get to options in most apps, but having the GW4 on dpi 200 is a mess, the tiles are just shrunk down and attempting to work in the top left quarter of the watch while sometimes elements from them(like weather) will try to centre making things overlap and ruin the visuals.
Is there any way I can have my low DPI without having janky tiles? am I just choosing bad DPI numbers with the ones I have tried and that is what is causing it? Preferably id like to be able to choose the DPI per app but I assume that isnt possible
Let me put it this way. You use android smartphones for some time, right ? At last 8 years, right ? Have ever seen in any android phone dynamically adjusted DPI per app ?
I'm not sure if it's possible to change DPI per app via ADB, but you should be able to decompile each APK and manually set the DPI in Android Studio. It could be a lot of work if you want to customize a lot of apps, but it's an option if it's important to you.

I am not shure if it is move in the right direction. Lets say you rework app to 100 dpi BUT display will still work in 200 dpi. So the visual will be distorted.
This is not Windows where app can set display of the monitor to required resolution.
I don't know per app but you can increase or decrease all on your SW4.
