How to Fix Dead Pixel or Stuck Pixels of Green, Blue, Red?

Are you seeing a single flashing pixel, multiple ‘stuck’ pixels or total black splotch on your digital PC monitor? Is it driving you crazy when you try to watch videos, play games, or read text? It can be very frustrating when even a minor disruption does not allow you to enjoy a normal viewing experience. Well despair no more!

Is there anything we can do about this? Worry not! We have just the solution for those pesky dead pixels and stuck pixels in the form of simple solutions like rubbing, and pressure tapping.

I will explain what is green, blue, or red dead/stuck pixels quickly and effectively with techniques so that you can get back to using an enjoyable viewing experience as soon as possible.

Dead Pixel vs. Stuck Pixels

Dead Pixel vs. Stuck Pixel

What is a Dead Pixel?

A dead pixel is a defective pixel on an LCD (Liquid Crystal Display) screen. It appears as a black spot or a colored dot, usually located in the center of the screen and does not light up. Dead pixels can occur due to physical damage, no power supply manufacturing defects, or environmental stress such as high temperatures and humidity levels.

The reason is to occur when there is a lack of connection between transistors and the liquid crystal in the display. This results in a single area where no light gets through and thus appears to be “dead”.

A few dead pixels may be unnoticeable; however, if there are too many of them then it can significantly compromise image quality. In some cases, replacement of the LCD panel may be necessary to fix this issue.

Some manufacturers provide warranty coverage for dead pixels so it’s important to check with the manufacturer before attempting any fixes yourself. Fortunately, most modern displays have very few occurrences of dead pixels so they are not a major concern.

What is a Stuck Pixel?

A stuck pixel is a defective pixel on an LCD (Liquid Crystal Display) screen. Unlike dead pixels, which appear as black spots or colored dots, stuck pixels are permanently lit up in one of the three primary colors—red, green and blue. They can be caused by physical damage to the display or manufacturing defects.

Stuck pixels can typically be repaired with software tools that flash different colors rapidly over the affected area. If this doesn’t work then it may require replacement of the LCD panel or other more intensive repairs depending on the severity of the issue. In some cases, it might even be necessary to send your device back for repair from the manufacturer.

Again, like with dead pixels, most modern displays rarely contain stuck pixels so it’s not a major concern.

List of causes of dead pixels and stuck pixels:

Stuck and dead pixels are two common types of pixel defects that can occur on LCD (Liquid Crystal Display) screens. Dead pixels appear as black or colored dots which do not light up, while stuck pixels are permanently lit up in one of the three primary colors—red, green and blue. 

These types of issues can be caused by:

  • Physical Damage – This can occur if the display is dropped or exposed to an external shock such as static electricity.
  • Manufacturing Defects – Some displays may have a higher number of dead pixels or stuck pixels due to poor quality control in the production process.
  • Environmental Stress – High temperatures and humidity levels can cause some pixels to become defective over time.
  • Software Issues – It’s possible for software glitches to cause stuck pixels to appear on the screen. For example, if the device has been subjected to overclocking monitor then this could result in extra strain on the display and cause pixel defects.
  • Age – As LCD screens age they are more likely to suffer from pixel defects due to wear and tear.
  • Dead Transistors – If there is an issue with one or more transistors in the LCD panel then this can cause pixel defects. This is usually a manufacturing defect and can’t be repaired.
  • Overheating – Excessive heat can cause some parts to malfunction and lead to dead pixels or stuck pixels.
  • Poorly Designed LCD Panels – Some poorly designed LCD panels may be more prone to dead pixels and stuck pixels due to a lack of quality control in their construction.

Fortunately, they are not a major concern on modern displays. In most cases, they can be fixed with software tools or the replacement of the LCD panel depending on severity. 

How to Prevent Dead and Stuck Pixels?

The best way to prevent dead or stuck pixels is to take care of your device and use it properly. Here are some tips that may help:

• Use the recommended settings for your device. If you’re unsure how to set up a certain display feature, check with the manufacturer’s website or user manual.

• Make sure that the temperature and humidity around your device is ideal for its operation. Excessive overheat of computer can damage electronics, leading to issues such as dead and stuck pixels.

• Clean your device regularly by using only anti-static cloths and cleaning products designed specifically for LCD screens. Be extremely careful when cleaning your device, as rubbing too hard can cause more harm than good in this case.

• Never attempt to fix a dead or stuck pixel yourself. Such attempts can cause more damage and render the device useless.

• If you do notice any abnormalities in your device’s display, such as dead or stuck pixels, take it to a qualified technician for help immediately. They will be able to diagnose the issue and suggest solutions.

• If you’re buying a new device, make sure you check for any sign of defects on its screen before buying it. This will save you from the hassle of sending it for repairs later on.

• Be aware of the warranty conditions with your product when purchasing it — some manufacturers may be willing to replace certain displays if they have too many dead or stuck pixels present.

• Lastly, remember that dead and stuck pixels are relatively rare. It’s not a common issue, so don’t panic if you do spot one! With proper care and use of your device, such problems can be prevented.

What is Pressure Tapping?

Pressure tapping involves lightly tapping on the back of the monitor (or wherever you see the dead/stuck pixels) of personal computer with your finger in an attempt to jar loose any stuck transistors, allowing them to connect properly again.

This can work for both stuck and dead pixels. Be sure not to be too rough when doing this as it may result in more damage than good.

What is Rubbing?

Rubbing involves using a soft cloth to lightly rub around the dead/stuck pixel in an attempt to jar it loose. This can also work for both stuck and dead pixels. Be sure not to be too rough as this may damage the monitor.

If you find a dead pixel in your display, there are several techniques that can be used to attempt to repair it. In some cases, running certain applications or adjusting the display settings may help revive the stuck pixel. Additionally, manually rubbing the spot with a clean cloth can sometimes help remedy the issue as well.


Dead and stuck pixels are common problems that can occur on LCD screens, but in most cases, they can be easily repaired.

Dead and stuck pixels can be quite annoying, but that doesn’t mean you have to suffer through them forever! With simple techniques like pressure tapping and rubbing, you can quickly get your monitor back into working order with minimal effort.

If you have a device with this issue, make sure to take the necessary precautions to prevent further damage from occurring. Additionally, if you’re buying a new device, make sure to check for any dead or stuck pixels before making the purchase.

So if you ever find yourself with a dead or stuck pixel on your screen, remember these tips and don’t despair! You can easily fix the problem and get back to enjoying your computer.
