With its intelligent DPI adjustment system, the app ensures that all elements remain proportional, providing a smooth and natural display experience even after modifying resolution settings.

Safe Resolution Verification to Prevent Errors

Applying an unsupported resolution setting can cause the screen to become unresponsive, making it difficult to restore normal functionality. To prevent this, verifies all resolution changes before applying them, ensuring that the selected settings are compatible with the device’s display capabilities.
