FAQ

Does this fix stuck pixels?

This tool is detection only — no flash repair animations or defect reports.

How does Auto play work?

It cycles White → Black → Red → Green → Blue every 3 seconds, including while fullscreen. Press A or the Auto play button to toggle.

Why a fixed color order?

White → Black → RGB covers dead (black) and stuck (primary) cases consistently.

Dead pixel vs stuck pixel?

A dead pixel stays black on all colors. A stuck pixel stays red, green, or blue (or bright) when other colors should show.
