What is a dead pixel, what is a stuck pixel?
Before we let you know how to fix dead pixels on your screen, we need to make sure that you know what a dead pixel is. Any modern screen, whether it is an LCD or an OLED screen is in fact composed of a large number of dots. Each of these dots can turn on or off and switch to different colors depending on the image that you computer wants to display. These dots are called pixels. No, we have made an extensive article on the topic, but here you should distinguish dead pixels from stuck pixels. A dead pixel is commonly a dot on your screen that remains black, whatever the image displayed is. Pixels can also be stuck on different colors.
How can I check if I have dead pixels or stuck pixels on my screen?
The procedure to run a dead pixel test is quite simple. First make sure your screen is clean. Then use our dead pixel test to display colors on your full screen. Carefully inspect your display for any badly displayed dot.
How can I fix dead pixels on my screen?
Once you’ve identified dead pixels on your screen, there are a few things you can try. Please acknowledge that it is easier to fix stuck pixels than dead pixels. The most probable cause for a dead pixel is a dead transistor. Hence the electric current cannot pass by it anymore. Stuck pixels however are still capable of working, they are just stuck to one color on the RGB spectrum. Here are two dead pixel fix tricks (try them also on black pixels, you never know):
Try stimulating the dead pixel with a video
You may try to use one of our dead pixel fix videos above. The idea is to flash colors on your screen at a high frequency to try to wake the pixel up. First, go to this webpage and select your screen aspect ratio. Then set your screen brightness to 100% and play the video full screen. Please note that this technique might take several hours to work. Be patient!
Try applying pressure on the dead pixel
If the above technique did not work for you, try this at your own risk. And start by turning your screen off. Then grab a soft cloth and gently apply pressure on the dead or stuck pixel that you’re trying to fix. While maintaining the pressure, turn your screen back on and see if the dead or stuck pixel is working again.
Dead pixel fix did not work for me. Are dead pixels covered by warranty?
The simple answer is "it depends". It depends on how many dead pixels you have, how old your screen or device is and how benevolent the maker of your screen or device is. Generally, only a couple of dead pixels is not considered as an issue that might be covered by warranty. But brands like Apple have been known to replace devices affected by dead pixels even after their warranty. Bottomline: if our dead pixel fix tricks did not do the job, it is worth trying your luck with your screen manufacturer.
