What are dead pixels? Dead pixels are pixels that don’t change color. For instance, if you are photographing a red background and you end up with pixels not displaying a red color, you have a problem with dead pixels.
What does a dead pixel look like and do they only appear on camera screens? Dead pixels are not only a problem in photography. They can appear on all LCD screens including phones, camera displays, and monitors. The trick is knowing what to do when you come across a dead pixel.
What Does Dead Pixel Look Like?
Dead pixels are often made up of areas that stay in the same place even when you move your camera around. One of identifying the problem is to take a photo and zoom in. If you find any areas that look flat and don’t comply with the rest of the photo, you may have dead pixels in that area of the frame.
It is worth noting that dead pixels are black.
When does it happen? It can happen during any kind of photography. It does not matter if you are snapping flat lay images or other still life photography, you can experience dead pixels. The color you are photographing does not influence if dead pixels are going to appear on your screen or not.
What Are Stuck Pixels?
While we are on the subject, let’s talk about stuck pixels for a moment. The main difference is the color of the pixels.
As mentioned, dead pixels are black. Stuck pixels are normally green, blue, red, or yellow. You may have seen stuck pixels on your TV screen. If you receive your TV via the Internet and the speed is temporarily reduced, you may experience stuck pixels.
Stuck pixels remain in one place and do not change color. Can stuck pixels be black? Yes, they can. A stuck pixel does not have to be a bright color – it can be black as well.
As far as photography goes, stuck pixels are easier to deal with than dead pixels.
What Does A Dead Pixel Look Like On a Monitor?
What do dead pixels look like? On a monitor, dead pixels look like black and flat areas. Fortunately, there are specialist sites online that can help you to identify dead pixels.
Two of the best sites that I have come across during my career as a product photographer are LCD Dead Pixel Test and Bad Pixel Test.
Before you go ahead and use the sites, it is important to make sure your monitor screen is clean. But, don’t rub your screen too much as it may even make the problem worse. The last thing you want to do is to damage your screen.
If you are working outside, you can check for dead pixels using your phone. The app Dead Pixels Test and Fix is an excellent choice for amateur product photographers using their Smartphones for photography.
Tips For Getting Rid of Dead or Stuck Pixels
Fortunately, there are ways in which you can get rid of both stuck and dead pixels.
Before you get too involved, it is best to start with a simple solution. Check the screen on your monitor to make sure it is not dusty. Screens do attract dust. Sometimes when you use a lot of photo editing programs, you become blind to dust.
Here are some simple tips I have picked over the years as a professional product photographer.
- Restart your device. This is perhaps the most straightforward solution. No matter how sophisticated your screen is, it will experience glitches from time to time. The easiest way to clear glitches is to restart your device. If you are working online, you can try refreshing the page.
- Our eyes can play tricks on us. I know only too well that our eyes play tricks on us. Sometimes, we see things that are simply not there. You may also be looking at a blemish. When your eyes feel tired, you are much more likely to see dead pixels. Step away from the screen and make yourself a coffee. If the area of concern is still there, you should try wiping the screen with a cleaning solution and a cloth.
- JScreenFix is a free online service that you can use. There is nothing to download. JscreenFix is the best solution for stuck pixels but it does work for dead pixels as well. The site is easy to use and the instructions on how to use it are easy to follow.
Can I Really Fix Dead Pixels?
To be honest, if you have dead pixels, you may have to call in a specialist. But, I have to admit that most of the “dead pixels” I have found in my work are stuck pixels.
Are Stuck Pixels a Permanent Problem?
No, they are not a permanent problem. You can fix them and get rid of them using special programs as we mentioned.
Are Dead Pixels Contagious?
In other words, do dead pixels spread? Dead pixels are often down to a small fault in the display. They normally don’t spread.
If they spread, you need to call in the professionals. For instance, you may have to replace the screen or buy a new camera. Most camera screens on mirrorless cameras are excellent and you don’t experience a problem.
I have experienced more dead or stuck pixels on monitors than on camera screens.
How Common Are Dead Pixels?
The problem with dead or stuck pixels is not that common. Still, if you work as a photographer and do a lot of photo editing, you may come across the problem.
Niggles like dead or stuck pixels are annoying. Don’t forget that your eyes may be playing tricks on you or your screen may be dusty. In the past, when I experienced a problem, I found that I have been able to rectify the issue using a website like JS creenFix.
