Sometimes, it’s not the software or hardware components of your PC that fail; it’s the monitor. If you need to fix your computer monitor, there are a number of steps you can take. These common solutions will fix most problems you have with your computer monitor.
Dead pixels: Over time, some monitors can develop dead pixels. Basically, these look like little black dots on your screen. If you have a high resolution, they can be so hard to spot that they’re insignificant. However, if you do spot them, they can quickly become an annoyance. If you find dead pixels on your monitor within a few months of making your purchase, you can usually return it immediately under warranty.
However, you may not want to return your monitor just yet. Sometimes, all you need to do to fix your pixel is to run it through a cycle of different colors, which can be done using software, or even certain Youtube videos. This works especially well for ‘stuck pixels’ – which become trapped on a certain display color.
Look in your video card settings: Many video cards come with a control panel in which the user can change a number of different display settings. If some of these settings have been changed, your monitor may display errors. For example, if you have tried experimenting with dual screens, then your settings may still be adjusted for a smaller, disconnected screen. Try reverting to default settings to make sure that this isn’t the case.
Adjust monitor settings: Those buttons on the sides, top, or bottom of your monitor actually do something. Using them, you can fix a number of different monitor errors. For example, if your monitor is way off to the side, these buttons will help you adjust it towards the center of your screen. There are also buttons which can change the color settings, contrast, and more. Some recent monitors will even feature a setting for cool or warm colors, each of which can change the appearance of your monitor.
Color, display errors, and freezes: If your monitor is showing color errors, freezes, and other display errors, then it may be the cause of a faulty video card, not the monitor. Update your video card with the latest drivers, which can sometimes fix the problem. Or, if these display errors occur after running your computer for a certain length of time, then they may be a result of excess heat. Video cards, especially when running video games, can overheat very easily, leading to pixilation, odd coloring, and other display errors on your PC monitor.
Fixing a flickering monitor: If your monitor display is flickering, it may be the sign of a loose power cord. Or, it can indicate a serious, irreplaceable problem with your PC screen. Check if other people online are having the same problem as you, or try returning it under warranty.
