Red pixels on the monitor can always be a pain. I remember seeing one red pixel in the corner of my monitor for weeks and it always annoyed me.
Luckily I have found some solutions to fixing red pixels on monitors and some of them are very simple fixes.
Let’s dive into the five fixes down below.

Change HDMI Cable
Before you try any other solutions, I want you to try this one. This is the simplest fix and is one of the most common causes of red pixels. What happens is that your cable gets too old, is faulty or gets damaged.
Then the cable will start producing red pixels on your monitor through the GPU. Sometimes all it takes is for you to buy a new HDMI cable or swap it out for another one that you already have.
Also, I recommend unplugging the HDMI or DVI cable, whatever is connected to your monitor from your graphics card. Then clean it carefully with some sort of brush and then replug everything back in.
If your HDMI cable is over 2-3 years old then you should replace it and see if it fixes the issue. These cables are pretty cheap online. You can also upgrade to a DP cable if you have a good GPU and monitor which is a very high-quality cable and you most likely won’t see red pixels on your monitor with that.
The GPU is what powers the display on your monitor, it processes all the video information and shows images on your monitor. Sometimes the GPU needs to be reseated which means unplugged and plugged back in again.
If you have a desktop PC this is very easy to do, but on a laptop its nearly impossible so skip this step.
Make sure when you reseat your GPU that you clean out any dust in the slot preferably with compressed air. Then place the GPU back in the slot and make sure the latches click which means its fully in place.
After that make sure you screw it down tight so it doesnt wobble or come off the pins.
If you have one red pixel like I did, it may be a case of it being stuck. There are some softwares that you can download like Jscreen, Undead Pixel, and Pixel Healer which can unstick the pixel for you.
Simply google the unsticking tool you want and download it.
You can also try and manually press down on the red pixels on your monitor and see if it fixes the panel.
You can change your monitor resolution to see if the issue resolves itself. Do this by going into the monitor settings and changing the resolution by 10% to see if it fixes the issue.
update display drivers
This one is a nobrainer and it’s one of the easiest fixes that doesn’t require taking your PC apart. If you have an Nvidia card then download Nvidia geforce experience or download your drivers manually from Nvidia Driver website.
Make sure your display drivers are up to date. If you have an AMD then do it on the AMD website. If you have integrated graphics then you can go to your device manager and right click on the graphics card and click update driver.
There are some features with AMD and Nvidia that removes these pixels. Like Intel’s smoothvideo function and Radeon’s overdrive function.
Upgrade GPU or monitor
Sometimes your GPU or monitor is too old and it causes the red pixels on monitor. Maybe you have an old LCD monitor which is past it’s due date and is producing the pixels. You can test this by changing monitor and seeing if it still occurs.
Another reason is maybe your GPU is just too old, you might have a super old 1000x series Nvidia card which is just dying or is filled with dust.
You can clean your GPU with compressed air, they get really dirty because most of them have fans inside which collect dust.
If you don’t want to buy new stuff, then I suggest waiting it out to see if it resolves itself over the course of a week or so.
Fixing Red Pixels On Monitor for laptop
The first thing you should do if you have this problem on a laptop is to get it checked out by your manufacturer if it’s still under warranty. AppleCare for MacBooks is an extended warranty that will fix this.
With Windows PCs you have warranties from all sorts of brands too and this is a manufacturer issue not an accidental damage issue which means you will be covered.
You can check if your laptop problem is the display or the hardware by connecting a different monitor to it. If the external monitor has no red pixels then it means your laptop GPU or motherboard most likely needs a replacement or driver update.
Red pixels on monitor are very annoying and can mess up your experience. If they are flickering all over the place then most likely you have a bad HDMI cable, monitor or GPU. You can fix this by updating your GPU drivers and switching out your HDMI cable. If all else fails, then you might need a new GPU or monitor.
