Start EIZO Monitor Testġ Pixel warranty varies by manufacturer. You should also clean the display prior to testing, since reflected light could cause dust particles to look like defective pixels. In order to ensure meaningful test results, your monitor should already be warmed up prior to testing (ideally for 30 minutes). This allows you to precisely assess even dark image areas. It is recommended that you carry out the monitor test in a dark room. For this reason, please note the manufacturer specifications (especially for the defective pixel test). You should therefore always assess your monitor within the context of its respective device category. For example, gaming monitors are distinguished by particularly short response times, whereas graphic monitors impress with a particularly homogenous image display and smooth gradients. The EIZO monitor test consists of various test scenarios that your monitor can handle to a greater or lesser extent, depending on the model. You can check your monitor for defective pixels and get a sense of its viewing angle stability. You can carry out 13 individual tests to check how uniform the image display is across the entire monitor, for example, or if the text is displayed sharply. Some manufacturers will replace a monitor that has even a single faulty pixel, while most manufacturers will require a minimum number of faulty pixels before offering warranty service.The EIZO monitor test lets you quickly and easily assess your monitor’s image quality. Different manufacturers have different policies for dealing with stuck or dead pixels. Unfortunately, a single faulty pixel may not be enough to get service under warranty – even if you’ve just recently purchased your computer. Again, be careful – don’t apply too much pressure or use anything sharp you could easily damage your monitor and end up wishing your only problem was a stuck pixel. If you’re pressing and rubbing, try using something that won’t damage your screen, like a microfiber cloth – and don’t press too hard! Some people also report that tapping on the screen with a blunt, narrow object like an eraser nub or the cap of a sharpie (it may be a good idea to wrap it in something like a microfiber cloth, too) can help. Some people report that pressing and rubbing on the pixel can help reset it. Its main tool will give you a little flashing dot that you can drag and drop anywhere on your screen – drag it over the dead pixel and let it run for at least several hours. It has a built-in stuck pixel locator that cycles colors on your screen. Try UndeadPixel (UDPixel) if you’re looking for a program that does this. Some people have reported this can help unstick a stuck pixel. If a color-cycling window is placed in the area of the stuck pixel, the program is constantly asking the stuck pixel to change colors.

Yes, this is a hardware problem – so how will software fix it? There are software programs that rapidly change colors, cycling through a variety of colors on your screen. Some stuck pixels will unstick themselves after a period of time – this can take hours, days, weeks, or even years. Whether any of these methods will work depends on what exactly is wrong with the pixel, so there are no guarantees. This is the computer monitor equivalent of banging on the side of your television (no, don’t hit your computer monitor!). So you’ve got a stuck pixel – what now? There are some purported ways to fix a stuck pixel, although there’s nothing definitive. Image Credit: ~dgies on Flickr Fixing a Stuck Pixel if it doesn’t move, that’s a stuck (or dead) pixel.
Of course, a speck on your screen may in fact be a piece of dirt or dust – run your finger over it (gently!) to make sure. Try several of the links to ensure you notice the pixel, no matter what color it’s stuck at. To easily do so, use the Dead Pixels Test website – click the links on the page to open a new browser window with the color and press F11 to make it take up your whole screen. The easiest way to notice is by making the screen a single color. Image Credit: Brandon Shigeta on Flickr Locating Stuck Pixelsĭo you have any dead pixels? It can be hard to tell. While a dead pixel may simply be stuck at black, it’s possible that the pixel isn’t receiving power at all.Ī faulty pixel displaying the color white all of the time is known as a “hot pixel.” While it’s often possible to “unstick” a stuck pixel, it’s much less likely that a dead pixel will be fixed.
