Hello, i have the 1cm dead touchscreen zone in the top and bottom, not good for the android taskbar...
Can we recalibrate the resolution / screen parameter to reduce a little the screen height to fix the problem ??
Thank you.
same problem here .. heeeelp

Than You, i had no success with NOMONE Resolution Changer, impossible to install for me tough Play Store (not allowed in my country) and the multiple apk found on the net was not good, an error 'probleme with parsing installer' something like this.
I found "Resolution Changer Pro" who work very well, the perfect resolution for me is : 970 x 768.
Or even easier, use a simple adb debug shell command:
Code:
adb shell
wm overscan 0,300,0,400
For this to work, you must have adb installed on your pc/mac and usb-debugging activated on your android device.
The above command will shrink the useful screen area with 300px from top and 400px from bottom.
Feel free to experiment those parameters to find the best fit for your situation.
Hi guys! I start to thank you a lot for your suggestions but before making any disaster i should be really grateful if you could give me an help.
I need to resize the screen of my Nexus 7 (2013) in order to fit with the car-dash enclosure where i'm willing to install it.
The enclosure i bought was supposed to fit for the nexus display but regrettably whilst the latter is of abt 15.3cm wide x 9.5 cm "tall" (sorry for my english) the enclosure has a window of 15.3 cm wide but only 8.7 cm tall which would make impossible the access to the softkeys.
In view of the above and considering also that there is no space available to enlarge the window of the enclosure i thought and hoped it would have been easier to resize the screen.
Now the question is: considering that the measures reported are relevant to the device in landscape mode may i kidly ask you the command variables that i have to amend to cut off the 0.8 cm on the bottom side of the screen (again landscape mode).
Thanks a lot in advance for your help!
Hello, Please i need help. I have a Dead Touch Zone (at the bottom 30% aprox.), i installed and i resized screen with ADB (adb shell wm overscan 0,0,0,600) BUT... I can´t use some apps (google play, whatsaap, etc) because it shows like they are behind backgroud.. Check pics attached for understanding.

Confirm the adb route works without root!

A long time since the original post and answers, but I thought it should be noted that this method works well. Thanks silvake.
My Mecer tablet stopped responding in the top 2-3cm after many years of loyal service. Could have been a drop or simply age. It is still useful and wish to give it to someone in need. So searching around and several different sites yielded some results. Note this is not a mainstream device so rooting was not an option nor attempted. Indeed drivers and any info is sparse for this device.
For anyone attempting this, I will outline my method and steps.
1. Enable USB debugging. There are many tutorials. Settings->About->Build number(tap x 7); Developer Options->USB debugging
2. Connect device with USB Cable. Give permission on device. You will need to make sure that windows installs drivers. At first windows failed to install all drivers. Not sure how it managed, but it connected eventually.
3. Download adb: https://android.izzysoft.de/downloads.php. I used https://android.izzysoft.de/downloads.php?file=adb-binaries-windows-29.0.4.zip. Decompress to desired folder. Open cmd to the folder.
4. Run adb.exe with 'adb devices' and confirm device is listed. First attempt showed:
D:\Downloads\Apps\adb-binaries-windows-29.0.4>adb devices
* daemon not running; starting now at tcp:5037
* daemon started successfully
List of devices attached
0123456789ABCDEF unauthorized
I had to give permission on the device. Reconnected USB.
D:\Downloads\Apps\adb-binaries-windows-29.0.4>adb devices
List of devices attached
0123456789ABCDEF device
Success! Device is now connected.
Next get the current display stats:
Type 'adb shell'
Confirm connection. Mine showed: [email protected]:/ #
Type: ‘dumpsys display | grep mBaseDisplayInfo’
Below is the capture of the operation:
D:\Downloads\Apps\adb-binaries-windows-29.0.4>adb shell
[email protected]:/ # dumpsys display | grep mBaseDisplayInfo
mBaseDisplayInfo=DisplayInfo{"Built-in Screen", app 800 x 1280, real 800 x 1280, largest app 800 x 1280, smallest app 800 x 1280, 55.84 fps, rotation0, density 190 (190.0 x 190.0) dpi, layerStack 0, type BUILT_IN, FLAG_SECURE, FLAG_SUPPORTS_PROTECTED_BUFFERS}
This is not really required but helps to determine the current stats to make a guess on the number of pixels to adjust the screen by.
Next is the command to adjust the screen. The 4 numbers are the coordinates. Since mine was the top area I adjusted only that.
Type: wm overscan 0,50,0,0
The update is live and you should see the screen drop 50 pixels from the top.
This was not enough for me so repeat until the pull down of the status bar starts working again.
Here is the whole list to adjust the screen until everything is working again:
D:\Downloads\Apps\adb-binaries-windows-29.0.4>adb shell
[email protected]:/ # wm overscan 0,50,0,0
[email protected]:/ # wm overscan 0,70,0,0
[email protected]:/ # wm overscan 0,80,0,0
[email protected]:/ # wm overscan 0,100,0,0
[email protected]:/ # wm overscan 0,200,0,0
[email protected]:/ # wm overscan 0,120,0,0
[email protected]:/ # wm overscan 0,140,0,0
[email protected]:/ # wm overscan 0,150,0,0
[email protected]:/ # wm overscan 0,160,0,0
[email protected]:/ # wm overscan 0,170,0,0
[email protected]:/ # wm overscan 0,180,0,0
[email protected]:/ # wm overscan 0,190,0,0
[email protected]:/ # wm overscan 0,195,0,0
[email protected]:/ # exit
So I had to move the screen 195 pixels down until the dead touchscreen area was excluded.
Screen is obviously smaller but the frustration of having to rotate the device 180 to be able to pull down the status bar is removed. Much worth it.
Now a child in need of education can still learn and we have saved the device from landfill and reduced the carbon footprint.
You might have to adjust the pixel density to compensate for the loss, but I left it untouched. Your results will vary so I cannot assist.
Excerpt from another site:
"Additionally decreasing the density through the settings (Display & lights > screen > LCD density) or the wm command helped compensating for the lost display area:
wm density 360"
Hope this helps someone as it helped me.

Hello amazing people,
I am looking for your guide/advice for solving a screen resolution issue.
I am using a 4:3 ratio screen with a LCD driver on Radxa Zero.
the poblem is that the screen looks stretched laterally. I think its due to aspect ratio becuase the lcd is of 4:3 aspect ratio.
can anyone help me how can I change the aspect ratio using adb?
I have worked with size and density but failed to produce any results.
Many thanks to this amazing community.

Hi,
I am new to the p7. I am used from my Samsung and nexus devices to adapt via build.prop DPI in order to see more things on screen.
Build.prop has no DPI setting. How (which app?) Proved to securely change DPI? And what is stock DPI for 1080 and 720p (rog)?
Thanks
No one feeling the need to show more on screen? [emoji22]
Hi,
Have you found a solution for this yet?
I've recently got myself a P7 and I'm trying to get something similar to 240 dpi(like my s3).
People have mentioned ROG tech, but I can't find that option anywhere.
ROG setting is under Settings - Power Saving, then menu (upper right corner) setting.
Rog? I tgought its resolution (I.e HD 720p instead of full HD1080p)? Is there also a setting for density hidden besides ROG?
rog doesnt do the trick
I've activated ROG, but all it does it help the battery to last longer, by reducing performance and screen res.
What I (and op) are looking for, is something to change the dpi (pixel density/LCD density). Like on samsung phones, you can do it through build.prop
No one managed to edit dpi?
Still have a problem...
Where.is the rog option in emui3?
changing dpi on P7 ??? such little screen ?? NO POINT it is tiny already ..
- Please install this app on your phone > https://play.google.com/store/apps/details?id=com.crystalmissions.dpichecker
- Set display size to default settings
- Open DPI Checker app
- Take a screenshot (Volume Down + Power Button)
- Post Screenshot here (Under the 'Attach Files' Section)
After the latest update, about a week or two ago, I noticed a fuzziness to my display with jagged icon edges and odd font sizes. I downloaded the above app, and when I opened it, it stated something like 320x533, I really cant remember, but it was a really far off display density from the Moto E4 Plus' reported 720p - 720x1280.
I just want to see if other are having this issue or if it was just me. Thanks.
The below screenshot is an example. I have already set my display back to 720x1280.
Code:
adb shell
Code:
wm size 720x1280
Code:
wm density 320
Anybody?
I can't seem to find the attachments button
photos.app.goo.gl/Tu7PhsYgOxX1NM0y2
Hmmm... Wonder why my display is so off...
Thanks for posting.
@qweedleguy screenshot:
About to pull the trigger on two 4xls. Looked at a Verizon version at Best Buy yesterday which was not in "demo mode" like the one on the Google stand. I couldn't see any toggle to bring the screen resolution down to a 1080p or equivalent ratio to save battery. Did I not see it?
I also couldn't see double tap to wake and shut options like on my current oneplus 6t that I have gotten very used to. Any luck with that?
There is no toggle to bring down the resolution, but with a few adb commands (you'll have to enable developers options) you can get it down to 1080p
adb shell wm density 444
and
adb shell wm size 1080x2280
Double tap to wake is there. If you are open to using a different launcher, you can use double tap to turn the screen off without hindering the biometrics. Both lawnchair and nova launcher support this within their gestures submenus.
There's not much battery saving, if at all, with lowering the screen resolution.

Thanks. Can I assume that enabling developers options is enough and no need for root? I will surely give it a try if I don't have to root.

That was interesting. I guess if screen is made QHD there's no sense in throttling it down to FHD.

Exactly. I would just keep it as is.

Hi guys!
Does anyone know how we could change the resolution on the phone. Or at least the external screen?
My use case would be connecting the phone via USB-C to a TV.
TV is 1920x1080 and phone is 2340 x 1080.
Because of that I get black bars on top and bottom.
It's also only a mirror image. Is there some app or way to kill the mirror of the screen and then launch an app only on the connected screen in whatever the resolution the screen is (most often 1920x1080)
My use case for this is to play with bluetooth joysticks on a TV for example.

I use second screen to change resolution and dpi settings, you need to do a bit of back end work to support, the app walks you through the options but only allows mirroring.

App requires root unfortunately
You can run the following on a pc with phone in developer mode and USB debug
"adb shell pm grant com.farmerbb.secondscreen.free android.permission.WRITE_SECURE_SETTINGS"
You need to install Android sdk. Command line on pc but you do not need to root phone.

Thank You!
Does this work guys?
It's annoying the black bars on top and bottom.
Before I try, do I need to have it plugged into the pc and TV at same time?
Or once done it's change forever?
Cheers
Has anyone noticed when connected via USB-C to the monitor/TV now, Tablet mode is missing on Android 10 (compared to 9) it only has Mirror and TwinDock Modes now where as before it has the 3 options.
yes this does work, ive just done my Motorola nexus 6
Setup ADB on your PC.
Enable USB debugging on your phone:
Open Settings & go to About phone and tap seven times on Build number, this will enable Developer options.
Now go back to Settings and youll see Developer options, open it.
Tick the USB Debugging checkbox.
Connect phone to the PC.
Open a command window on the PC and issue the following commands to change screen resolution to 720 x 1280 and density to 280:
adb shell wm size 720x1280
adb shell wm density 280
Reboot phone with the following command:
adb reboot
this works perfect playing codmobile, it no longer overheats and gaming become alot faster for me
the asus rog 2 has a physical resolution of 1080 x 2340 Pixels, and a pixel density of 391 on a 6 inch screen
change it to
adb shell wm size 720x1280
adb shell wm density 280
and you will notice longer battery life, no more overheating and your gaming will become alot faster.
