Screen Test Pro

Screen Test Pro is a powerful Chrome extension designed for in-depth testing of mobile phone and tablet touch screens. It provides detailed information about screen characteristics such as resolution, pixel density, DPI, and available screen area. Users can assess screen color rendering and detect dead pixels or bright spots at a glance. The extension features grayscale and multi-touch testing, full-range touch area verification, and screen leak detection to ensure display integrity.

Beyond visual tests, Screen Test Pro measures maximum and minimum brightness for optimal reading experiences in varying light conditions, evaluates resolution sharpness, color reproduction accuracy, and touch screen pressure responsiveness. It also includes white balance analysis to detect warm or cold color tones.

In addition to screen diagnostics, the extension identifies and lists all supported device sensors such as accelerometer, gyroscope, magnetic field, proximity, ambient temperature, heart rate monitor, and many more. This comprehensive sensor detection helps users understand their device capabilities thoroughly. Screen Test Pro is an essential tool for developers, technicians, and tech enthusiasts aiming to verify and optimize device screen and sensor performance.
