Even though most Android devices today come with good resolution and pixel density, sometimes you may need to change resolution of your display for various reasons.
Gaming is the most common reason. Sometimes you may want to play a game, but it’s putting strain on your processor and causing your game to lag. You could then reduce the resolution or pixel density of your display to make it easier on your processor, allowing your game to perform better on your device.
Plus its been found that reducing resolution or pixel density could improve your battery life as well since most of your device’s battery consumption is caused by the display.
Fortunately, it’s super easy to change resolution or pixel density on Android devices. If you have rooted your phone, it will be as simple as downloading a resolution changer app from the Google Play Store to start changing resolution on the go.
You could use this app for checking out your device resolution and pixel density.
If your device is not rooted, no need to worry. You can easily change the resolution of your display, all you need is a computer (Windows, Linux, or Mac) and data cable and you will be good to go.
Change Screen Resolution on Android
Method 1: Without Root
In this method, we will use Android Debug Bridge (ADB) to connect your device to a computer and issue commands to it. ADB is a command-line tool that lets you communicate with your device and is used for various actions like installing and debugging applications, changing resolution, etc.
But before you can start changing your device’s resolution using ADB, you will have to enable USB debugging on your device from developer options. You can access developer options on your device by going to Settings -> System -> Developer options.
If you can not see Developer Options in your settings, don’t worry it’s very easy to enable it. Just go to Settings -> About phone and find the Build number option there as shown in screen below.
Now tap on Build number multiple times (7 times to be specific) and you will enable Developer options for your device.
Now go to Developer options and scroll down and search for USB debugging option and enable it. Now you can connect your device to a computer using a data cable.
It’s time to take control of your phone from your computer. Open command line (terminal on Linux) and browse to the directory where you installed ADB as shown in screen below and issue command ‘adb devices’ and you should see your device on the list.
Now issue the ‘adb shell’ command and you will be able to communicate with your android device. Before changing resolution, it is advisable to make a note of your current resolution and density. Issue ‘dumpsys display | grep mBaseDisplayInfo’ and note down your resolution and pixel density.
Now you can change the density or resolution by using the following commands. You can change pixel density number from range 120-600.
wm density DPI (Change display density)
wm size RES (Change display resolution)
Changes should be effective immediately, but if not, just reboot your device.
To give you an idea of the difference, here are a couple of screenshots of my device after changing resolution and density.

The without root instructions worked well for me. Thanks.
However, now whenever I go to print anything, the print spooler crashes.
When I restore the original density, the printing is fine again.
Printing is important to me, any ideas?
