Dead pixel test — fullscreen solid colors
Check for dead or stuck pixels with solid red, green, blue, white, and black fullscreen fields.
Open this light nowSteps
- Open Instant White and go fullscreen.
- Start with solid red (Dead pixels preset), then cycle green, blue, white, black.
- Scan slowly for pixels that stay dark (dead) or stuck on one color.
- 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.
