- You may find options to adjust the DPI (dots per inch) or screen width directly.
- Experiment with different values to find the optimal width for your needs.

Note that the availability of specific settings may vary depending on the version of WSA and the Android OS image.

Using ADB (Android Debug Bridge)

ADB is a command-line tool used for communicating with Android devices. It offers more advanced control over WSA settings, including the ability to change width programmatically.

Install ADB:
- Download the ADB binaries from the official Android SDK Platform Tools.
- Extract the downloaded ZIP file to a directory on your computer.
- Add the ADB directory to your system’s PATH environment variable.
Connect to WSA via ADB:
- Ensure that Developer Options are enabled in WSA.
- Find the IP address of the WSA instance (usually displayed in the Developer Options).
- Open a command prompt or terminal and run the following command: adb connect <WSA_IP_ADDRESS>:5555 (replace <WSA_IP_ADDRESS> with the actual IP address).
Change Width using ADB Commands:
- Use the wm size command to modify the screen resolution. For example: adb shell wm size 1280x720. This command sets the screen width to 1280 pixels and the height to 720 pixels.
- Use the wm density command to adjust the screen density (DPI). For example: adb shell wm density 240. This command sets the screen density to 240 DPI.
- Reboot the WSA instance for the changes to take effect: adb shell reboot.

Caution: Incorrectly using ADB commands can lead to instability or display issues. Always proceed with caution and research the commands thoroughly before execution.

Using Third-Party Apps and Tools

Several third-party apps and tools can simplify the process of changing width and other display settings in WSA.

Resolution Changer Apps:
- Apps like “Display Changer” or “Resolution Changer” can be sideloaded into WSA to provide a graphical interface for adjusting screen resolution and density.
- These apps often offer presets and custom settings to optimize the display for specific apps or use cases.
Custom Launchers:
- Custom launchers like Nova Launcher or Apex Launcher can provide additional control over display settings and app layouts.
- Some launchers allow you to adjust the screen grid size, icon size, and other visual elements to optimize the display width.

Note: When using third-party apps, ensure they are from reputable sources to avoid security risks. Always review the app permissions and user reviews before installation.

Considerations Before Changing WSA Width

App Compatibility

Before changing width, consider the compatibility of your Android apps. Some apps may not scale well to different screen sizes or aspect ratios, leading to layout issues or functionality problems. Test the apps thoroughly after making changes to ensure they function as expected.

Performance Impact

Modifying the display width can impact the performance of WSA and the Android apps running within it. Higher resolutions and densities require more processing power, which can lead to slower performance or increased battery consumption. Monitor the performance after making changes and adjust the settings accordingly.

Aspect Ratio

The aspect ratio of the display is the ratio of its width to its height. Changing the width without adjusting the height can distort the display and make apps appear stretched or compressed. Maintain a consistent aspect ratio to ensure a visually appealing and functional experience.

DPI (Dots Per Inch)

DPI refers to the number of pixels per inch on the screen. Adjusting the DPI can affect the size of text and UI elements. A higher DPI makes text and UI elements smaller, while a lower DPI makes them larger. Choose a DPI that is comfortable to read and use on your display.
