Advice

  • If the methods above do not work, try to contact the manufacturer and change to another monitor. If it is imperative to replace a technical part, contact the manufacturer for specific discussions.

Warning

  • Many people believe that touching the screen will cause many pixels to be stuck, but this has not been proven.
  • Don't try to open the screen. Doing this will void your warranty and the manufacturer will not replace the screen for you.
  • Be careful with websites where you download screen repair software. Many sites with viruses are worse than stuck pixels.
  • Do not get the electrical equipment wet to avoid damage.
  • The LCD screen has many layers. Each layer is separated by a small glass gasket. These separate gaskets and layers are fine. Pressing the LCD panel with your finger or a towel can break the pad and make things worse. Most technicians do not fix stuck pixels with force method so take all risks when you do it this way.
  • Manufacturer's warranty for LCDs includes panel replacement if the display shows a certain abnormal pixel count. However, warranty does not cover damage caused by screen scratches or strong contact. Contact the manufacturer to see if the device can be replaced or repaired.
