What Is A Stuck Pixel?

A stuck pixel is a pixel on an LCD or OLED display that is not displaying the correct color. It is "stuck" on one color, which could be red, green, blue, or any combination thereof, resulting in a white or colored dot. This happens when one or more of the sub-pixels (the red, green, and blue elements that make up a full pixel) remain on or off and cannot change their state.

Stuck pixels are different from dead pixels; a dead pixel is always off (black), while a stuck pixel is always on or displaying the same color. Stuck pixels are generally considered less problematic than dead pixels because they have a better chance of being fixed.

How To Fix Stuck Pixels?

Here are some methods that might help fix a stuck pixel:

  1. Software Cycling: Use software designed to fix stuck pixels. These programs work by rapidly cycling the screen through a series of solid colors, which can sometimes get the pixel to start functioning properly again.
  2. Manual Cycling: If you don't want to use software, you can attempt a similar approach manually by displaying red, green, blue, and white images in full-screen mode, in hopes of unsticking the pixel.
  3. Pixel Massage: Turn off your monitor, apply pressure to the stuck pixel with a soft cloth to protect the screen, and use an object like a stylus or the eraser end of a pencil. While applying pressure, turn the monitor back on, then remove the pressure. This can sometimes get the liquid crystal moving again.
  4. Heat Method: Like with dead pixels, applying gentle heat to the area can sometimes get the liquid crystal flowing. This can be done with a warm (not hot) cloth or heating pad while the monitor is on.
  5. Tap Method: Gently tapping the area with the stuck pixel can sometimes get it to light up properly. This should be done carefully to avoid damaging the screen.
  6. Warranty and Professional Repair: If the stuck pixel is bothersome and the monitor is under warranty, check with the manufacturer for their policy on pixel defects. Alternatively, a professional repair service might be able to fix the issue if the above methods don't work.

Always proceed with caution when applying physical methods to fix a pixel, as there is a risk of causing more damage to the screen. If you're not comfortable with these methods or the pixel does not become unstuck, professional repair or replacement may be the best course of action.
