Touch Screen Test

The Touch Screen Test Chrome extension offers comprehensive display diagnostics right in your browser. It allows you to perform multiple tests including touch and sensor functionality to ensure your screen responds accurately. The extension tests primary colors — red, green, blue, white, and black — helping you identify any dead pixels or color inconsistencies.

Additionally, you can run gradient color tests in both color and black-and-white to check for smooth color transitions. The multi-sensor multi-touch test supports up to 10 simultaneous touches, verifying touch sensitivity and response across your screen. This tool is perfect for quickly assessing and troubleshooting your device's display and touch performance.
