How to run the test

  1. Click the Start screen test button below.
  2. The browser enters full-screen mode.
  3. Click the screen to cycle solid colors. The final click on Blue closes the test.
  4. Look for tiny dots with the wrong color or visible lines on the panel.
  5. Press ESC at any time to finish the test.

Clean dust off the screen before testing so specks are not mistaken for dead pixels.
