![]() ![]() Whichever method you use, remember the fix might not be permanent and can recur any time. You can use a software tool to do it or do it manually. There are a number of ways of fixing a stuck pixel. If you are still not sure, you can use the Dead Pixels Test Website to check if your screen has a stuck pixel or a dead pixel. A dead pixel is easiest to spot on a white background the pixel will look darker than the rest of the background, almost non-existent. The simplest way to identify if you have a stuck pixel or a dead pixel is to view the screen in different colors. The fundamental difference between the two is that dead pixels are irreversible and if you have a dead pixel on your screen, it is best to contact the manufacturer for a replacement or repair.Ī stuck pixel usually shows one of the three colors of the sub-pixel, whereas a dead pixel is usually black or white. In other words, a dead pixel is permanently turned off and you cannot fix a dead pixel. A stuck pixel can also be recurring occurrence even after it has been fixed.Ī dead pixel, on the hand, occurs when transistor that powers the three sub-pixels malfunctions. Sometimes, a stuck pixel becomes unstuck on its own. This is a reversible process and can be fixed by several methods. There is a difference between a stuck pixel and a dead pixel.Ī stuck pixel, as mentioned earlier is stuck in a single color. Difference between a Stuck pixel and a Dead pixel When the pixel does not change color as it should, you will see it as an annoying spot on the screen. It is usually caused when the transistor does not get enough power to change colors.Ī stuck pixel will then be stuck in red, blue or green and will not change color when you change the display. ![]() What is a stuck pixel and how does it get stuck?Ī pixel gets stuck when there is a faulty sub-pixel that is always on. We have outlined a few methods of solving the stuck pixel problem on your LCD screen. These colors combine to give you the final color on the screen. Each pixel on your monitor is made up of three separate sub-pixels in three colors of red, green and blue. The LCD screen is made up of hundreds of pixels that light up together to form the perfect image. When this happens, you might have a case of a stuck pixel or a dead pixel. Just a stubborn little black or some other color spot that doesn’t go away. So if you're a perfectionist looking for in-warranty relief, you may not have a leg to stand on unless your screen has a large number of pixel or subpixel defects you'll just have to hope that Nintendo eventually offers to fix any and all pixel defects, as it did for the original Nintendo DS back in 2004.Ever noticed an annoying spot on your LCD screen that refuses to go away? Maybe you have tried to clean it away without success. A couple of dead or stuck pixels or subpixels is completely normal, and Nintendo isn't alone in shipping screens that have a small defect or two. This is also broadly true of phone and tablet makers like Samsung, which will take a device with pixel or subpixel defects back if you exchange it in within the first seven days after purchase but otherwise allows for between one and four pixel defects depending on the kind of screen you're using and its resolution. Asus, Acer, AOC ( PDF), ViewSonic, and others all have slightly different policies based on what monitor you buy and how old it is, but they all stick close to the Class II guidelines. Apple encourages "concerned" customers to bring their computers in for evaluation, but doesn't define an acceptable maximum number of stuck pixels. Dell's fancier monitors can't have any bright sub-pixels but up to six dark subpixels are acceptable, while their lower-end displays can have between three and six bright subpixel defects. HP will accept up to five total subpixel defects, but zero full-pixel defects. Complying with these standards isn't mandatory, but individual companies' pixel policies suggest that they mostly try to adhere to the Class II guidelines.
