Display Calibration is a free Android utility developed by Technische Hintergrunddienste. This application is designed for users looking to enhance the quality of their screens, monitors, displays, or touchscreens by addressing issues such as uneven pixels, brightness irregularities, dead pixels, and color discrepancies. The calibration process is continuous and can be stopped at the user's discretion, making it practical for calibrating multiple devices and tracking previous calibration times.

The app offers features like dead pixel removal, screen remapping, touchscreen display resolution enhancement (device-dependent), calibration of all screen pixels, and rendering images more realistically. It is known for achieving significant improvements on various screens by stimulating display electronics and chemistry to enhance picture quality.
