Resolution & DPI Changer

Check, change and reset screen resolution, display size and DPI safely.

Resolution & DPI Changer helps you inspect and adjust Android's logical screen resolution and display density. It is designed for display scaling, readability experiments, custom layouts, and advanced Android workflows.

Understand the current display

Check the logical width, height, and density Android is using before you change anything. Resolution and density are separate values: resolution controls the rendered pixel grid, while logical density affects Android interface scaling.

Adjust the display deliberately

Enter a resolution or DPI value that fits your use case, calculate proportional values, and return display overrides to their defaults when needed. Record the original values before applying a change so you have a recovery reference outside the device.

Setup requirements vary

Android restricts system-level display overrides. Available setup and permission routes depend on the installed app version, Android version, manufacturer software, and device configuration. Follow the instructions shown by the app for your device.

Useful tools

• Read the current logical resolution and display density
• Calculate proportional resolution and density values
• Apply custom logical display values
• Reset display resolution and density overrides

Important limitations

This app changes logical display overrides. It cannot add physical pixels, increase the panel's native PPI, improve touch sampling, or guarantee better gaming performance. Some apps and manufacturer interfaces may not support every display configuration. Extreme values can make controls too large, too small, or difficult to reach.

Record your original values, make conservative changes, and confirm that important apps remain usable. If the interface becomes difficult to use, restore the original values before trying another configuration.
