Stuck pixels sometimes recover when their sub-pixels are switched on and off rapidly for a while. It doesn't always work, but it's safe for the screen. The fixer in the test above flashes, so read its warning first.

ขั้นตอน

  1. 1

    Find the pixel

    Use the dead pixel test to find it. Note which colour it shows.

  2. 2

    Start the fixer

    Choose Stuck pixel fixer, confirm the photosensitivity warning, and drag the small box over the pixel.

  3. 3

    Let it run

    Leave it 10 to 20 minutes. Look away from the screen; you don't need to watch.

  4. 4

    Check, then repeat

    Exit with Esc and check with the colour test. Repeat a few times if it's improving.

  5. 5

    Fall back to the warranty

    If it's still stuck after a few sessions, contact the maker with a photo.

  • Turning the display off for several hours occasionally helps too.
