Test Information
The Pixel Fixer is a dedicated maintenance utility designed to attempt repairs on “stuck” pixels by rapidly cycling sub-pixels through various color states. This high-speed stimulation can sometimes “unstick” the liquid crystals that have become trapped in a specific state.
This tool generates rapid, high-contrast flashing patterns. 🚫 DO NOT look directly at the screen while the fixer is running.
🧣 Cover the active area with a cloth or look away from the monitor.
🛑 Stop immediately if you feel any discomfort.
🔴🟢🔵 Solid Flash vs. Static RGB: “Solid Flash” cycles the entire area through primary colors, while “Static RGB” creates a high-frequency noise pattern. Both are effective; some pixels respond better to one than the other.
🎯 Spot Fix vs. Fullscreen: Use “Spot Fix” to drag a localized box over a specific defect. Use “Fullscreen” if you have multiple issues or want to “refresh” the entire panel.
⏱️ Timer: Set a duration from 1 minute to 60 minutes. Deeply stuck pixels often require at least 30 minutes of continuous stimulation.
📏 Size: Adjust the box size when in “Spot Fix” mode to perfectly cover the affected area.
🟥 Stuck Pixel (Colored): A pixel that is permanently Red, Green, or Blue. These have the highest chance of recovery (approx. 50-60%) using this tool.
⬛ Dead Pixel (Black): A pixel that remains black on a white background. This is usually a physical hardware failure (burned-out transistor) and is rarely fixable by software.
⬜ Hot Pixel (White): A pixel that is permanently white. These are often difficult to fix but can sometimes be improved by the “Static RGB” mode.
If the pixel is still stuck after 60 minutes, it may be a permanent hardware defect. You can try a second pass after the monitor has “rested” and cooled down. For new monitors, check your manufacturer’s “dead pixel policy” for replacement options.
This free online stuck pixel fixer works on OLED, LCD, and LED displays, including iPhone, Android, and Desktop monitors. No download required.
