GPU Artifacting Red Pixels [Everything You Need to Know]

Written By Farhan Max

Every Computer user has probably experienced GPU artifacting at some point. Red pixels are a common GPU artifact concerning users who depend on their computers for editing or productivity.


So in this article, I will look more closely at the root causes, symptoms, and solutions for GPU artifacting with red pixels.

Let’s get started.

What is GPU Artifacting Red Pixels?

Red dots and checkerboard patterns in monitor displays are frequently the results of GPU memory failure in the graphics device. Usually, the higher temperature of the graphics processing unit (GPU) is the main reason for this memory (RAM) failure.

There are several causes why your Graphics card may begin to artifact with red pixels. Overheating is one frequent cause of the Graphics card malfunctioning, resulting in visual abnormalities.

There are a few indicators to check for if you think your Graphics card is artifacting with red pixels.

First, users might see red pixels on their computer monitor either as larger groups of color or as solitary dots.

When using graphically demanding software, users might also observe that their computer is operating less quickly, with reduced frame rates or extended load times.

What Causes Flickering Red Pixels on Monitor?

Faulty display connections, outdated graphic drivers, and higher temperatures on the graphics device are the most common causes of flickering red pixels. Other reasons like a damaged computer display and a power supply problem also caused red flickering on the monitor.

There are additional causes for red pixels on your display to flicker. Simply read the part below to learn more.

Here are some causes of flickering red pixels on a monitor:

Faulty Display Cable

Faulty cables are among the most frequent reasons for flickering red dots on a computer display.

If the cable connecting your display to your computer is broken or loosened, signal interference can occur on the monitor. This signal interruption can result in red pixels flashing on the computer monitor.

Outdated GPU Driver

Another reason for blinking red dots on a PC display could be obsolete and defective graphics drivers.

Graphics drivers are in charge of showing pictures and videos on your computer, and when they’re out of date or not working adequately, red pixels may appear on the screen.

Higher Temperature


Higher temperature is another reason your display may show red dots on your display.

When your machine or graphics card becomes too hot, pixels may flicker, and the monitor may show red pixels.

Damaged Monitor

A malfunctioning monitor is another potential reason for flickering red dots. When a monitor gets dropped or bumped, the monitor can get damaged.

For this reason, a monitor can result in red pixels that flicker.

We now understand what causes the GPU artifacting of the red pixel on the display. So, in the part below, I’ll show you how to fix GPU artifacting.

How to Fix Red Pixels on a Monitor

Users can repair a red dot on a monitor by checking the display wire connection, updating the outdated driver, and running pixel fixer software. To repair red pixels on their monitor, users can also clean their computer display and replace faulty devices.

There are other methods for repairing a red pixel on a computer display. Simply follow the instructions below to find out.

The following are the steps for repairing a crimson pixel on a monitor:

1. Check Display Cable

The first step toward resolving red pixels on your display is to inspect the cables. Red pixels on the screen may occasionally appear because the lines linking your monitor to your computer can loosen up.

Make sure the cables are tightly attached to the machine and the display. Invest in new wires if the existing ones are damaged.

2. Update Drivers

Red pixels on your display can also be the result of outdated drivers. See if there are any graphics card driver updates available for your machine.outdated-graphics-driver

Upgrading your drivers can resolve the red pixel problem on your display. Driver updates are available from the company’s website or through the Windows Software update function.

3. Run Pixel Fixer Software

Pixel fixer software can help you repair red pixels on your display. These programs are designed to untangle the tangled pixels on the screen by flashing different shades.

Pixel fixer software is freely accessible online and is simple to use. Simply download and start the program, and it will try to repair the red pixels.

4. Clean the Screen

This solution may sound odd, but it’s worth a shot. Gently rubbing the screen with a cloth towel can sometimes resolve red pixels on your display.

The idea behind this technique is that it can help the monitor to remove the stuck pixels. Avoid applying too much pressure to avoid damaging the screen.

5. Repair or Replace Faulty Hardware

If the above options do not resolve the red dot on your screen, you can repair or replace the faulty hardware.

Before replacing or repairing the hardware, you must determine which component, such as the GPU or monitor, is causing the red pixels.

What is the GPU Artifacting Red Pixels Examples?

Red pixels in some areas on the screen, computer monitor flickering, and display blackout are typical graphics card artifacting instances. Checkerboard Artifacts, lines, and patterns on your desktop screen are all instances of GPU artifacting red pixels.

Other indicators exist that could serve as excellent examples of red pixel artifacting. Simply read the part below to learn more.

Following are some examples of GPU artifacting in the red pixel:

Red Dot on Screen: If you notice random red pixels on your screen, this red dot indicates that your graphics device is artifacting.

Screen Flashing: During intense activity, if your computer screen begins to flash without prior notice or indication. The red pixel on this flashing screen is a prime illustration of GPU pixel artifacting.


Lines Artifact: If the monitor displays different line artifacts during periods of light or intense workload, your GPU is artifacting. That is another instance of a crimson pixel being distorted by a GPU.


GPU artifacting with red pixels can be an annoying and troubling problem for computer users, but it isn’t always a reason for concern.

By troubleshooting and minimizing possible causes one at a time, you can find and resolve the problem and return to using your computer without interruption.
