    Frequently Asked Questions

    Can this fix stuck pixels?

    Stuck pixels sometimes recover after rapid color cycling or pressure applied to the affected area. This tool cycles red, green, blue, white, and black to stimulate stuck sub-pixels. Dead pixels cannot be fixed.

    What is Flash Mode?

    Flash Mode rapidly switches random colors every 80ms instead of a slow cycle. The intense stimulation may help unstuck sub-pixels that a slow cycle cannot reach.

    How long should I run the fixer?

    Run for 10–20 minutes on the stuck pixel area, then check if it recovered. Avoid running for hours as rapid flashing may cause eye strain or affect OLED panels.

    Is flashing safe for photosensitive viewers?

    Rapid flashing may trigger discomfort in photosensitive individuals. Use slow color cycle mode instead of Flash Mode if you are sensitive to flickering light.

    Is this stuck pixel fixer free?

    Yes. The stuck pixel fixer is free to use online with no download required.
