Whether you're troubleshooting dead pixels, calibrating color, or assessing touch accuracy, DisplayTester gives you a full suite of tests for both casual and professional analysis.

Dead Pixel Detection

Easily identify stuck or dead pixels with solid color background tests. Cycle through various hues to pinpoint issues that may affect display quality.

Color & Gamma Calibration

Fine-tune your screen’s color output with contrast, gradient, saturation, and gamma tests (gray, red, green, and blue). Perfect for verifying color accuracy and detecting banding.

Touch & Display Performance Tests

Test multi-touch accuracy, locate dead zones, and measure overall display responsiveness—essential for gamers, app developers, and touchscreen troubleshooting.

Real-World Image Comparison & Color Charts

Access high-quality sample images and charts to compare screen rendering capabilities, viewing angles, and color depth—even on wide-gamut displays.

Technical Info & Display Metrics

Gain insight into your device’s screen size, pixel density (DPI), GPU type, pixel format, and more. Includes a DIP/PX calculator and manual DPI measurement for design and development precision.

Burn-in Repair Tools

Repair or reduce screen burn-in with scrolling black-and-white bars or noise-based repair modes (Pro only), available in various color modes.

Google Cast Support (Pro)

Wirelessly cast your test patterns to a smart TV to evaluate its performance, color accuracy, and uniformity from a distance—ideal for home theater tuning.

Gesture-Based Controls

Swipe and tap to change brightness, cycle tests, or enter full-screen mode—all without interrupting your diagnostics.
