Steps

  1. Open Instant White and go fullscreen.
  2. Start with solid red (Dead pixels preset), then cycle green, blue, white, black.
  3. Scan slowly for pixels that stay dark (dead) or stuck on one color.
  4. Note positions; re-test after a power cycle if unsure.

Tips

  • Stuck pixels often respond to color cycling; dead pixels stay black.
  • Use agent links: /?c=red&b=100&f=1&w=1 and swap c= for other colors.
  • Avoid leaving max static colors for hours on OLED panels.
