  2. Click the big red box for full-screen mode.
  3. Check your display or use the screen as a source of red light.
  4. Press the Esc key or click the left mouse button to finish using the tool.

Purpose of Using a Red Screen for Testing Screens

  • Pixel Performance Assessment: The red screen highlights discrepancies in pixel performance, making defective pixels (dead or stuck) easily noticeable against the uniform red backdrop.
  • Color Calibration: It serves as a baseline for adjusting color settings.
  • Early Detection of Screen Issues: Regular use of the red screen in maintenance routines aids in the early identification of screen problems.
  • Prolonging Monitor Longevity: By revealing potential issues before they escalate, the red screen tool helps maintain consistent screen performance and quality, thereby extending the monitor’s lifespan.
