How to Fix a Stuck or Dead Pixel: 5 Easy Methods to Try
Modern digital displays are made up of pixels, or tiny blocks of light. Each pixel consists of a subpixel that emits different intensities of red, green, and blue color to create our favorite TV shows, movies, and games. Pixels can either be backlit by an additional panel like LCD screens, or individually lit like OLED screens, but both run the risk of stuck or dead pixels. Let’s take a look at the differences between the two and how to fix them.
Stuck pixels vs. dead pixels
We see vibrant images on our screens thanks to millions of colored pixels. But what happens when one or more of these pixels stops working? A stuck pixel is characterized by a stubborn dot of light appearing in the same place that does not seem to change with the rest of the image. It could be red, green, blue, or a combination. Stuck pixels may appear because of a manufacturing defect, a transistor failure, or a temporary electronic issue, and can disturb the viewing experience. Like other pixels, stuck pixels continue to receive power from the source, but incomplete information means they do not light up as intended.
In contrast, a dead pixel is always off and tends to display a continuous black color. They are usually the result of physical damage or a manufacturing defect and reduce the overall screen real estate. Dead pixels do not continue to receive power and are therefore more difficult to rectify.
How to fix a stuck or dead pixel
The first step to fixing pixel issues is to figure out whether it is a stuck or dead pixel. Digital display users can do this by switching to a pure black screen and observing whether or not any pixels are still lit. Similarly, switching to a completely white screen will reveal if there are any dead pixels, which will appear as a continuous black dot.
Once we know what kind of pixel issue we are dealing with, we can try to rectify it using the following suggestions.
1. Turn the monitor off and on
It may be a classic solution to many IT-related issues, but switching a computer monitor off and on can resolve stuck pixels that appear due to temporary electronic faults. Rebooting the device can re-energize stuck pixels and leave them working as normal. Try this method multiple times for stubborn pixels, but be aware it will not work for dead pixels.
2. Try software fixes
Downloading and installing software such as JScreenFix, PixelHealer, UDPixel, or DPT Dead Pixel Trainer can locate stuck or dead pixels and provide free solutions to try and fix them. JScreenFixstates it can fix many stuck pixels in under 10 minutes, while PixelHealer uses a tried-and-tested method of flashing RGB colors over dead or stuck pixels to revive them. These software are user-friendly and a good first point of call when resolving pixel issues.
3. Massage the area
A pixel massage, or gently massaging the area around the affected pixel, can also rectify stuck pixels. First, switch off the monitor and apply soft pressure to the area using a cloth to protect the screen. While doing this, turn the display back on and release the pressure. This method can release stuck pixels by getting the liquid crystal moving. However, users are advised to exercise caution when trying a pixel massage, as too much pressure can break the monitor.
4. Use a slightly warm cloth
Warmth can also resolve pixel issues and help liquid crystals flow properly. Use a warm (not hot!) and dry cloth and gently press it against the affected area while the screen is still on.
5. Use the Acer warranty
Acer device users experiencing dead or stuck pixels can check whether or not the device is still under warranty. Warranty upgrades such as a basic extended service to prolong coverage are available on the Acer website.
Stuck and dead pixels: final thoughts
Pixels are tiny lights that work together to create images in games, movies, or TV shows on our screens. However, as with any technology, they are susceptible to faults or damage. Stuck or dead pixels manifest as continuous black or colored dots on a device screen. Although they can be annoying, there are a few ways to resolve pixel issues. These include massaging the stuck or dead pixel, switching devices off and on again, or getting it fixed via the manufacturer if the device is still under warranty.
