How to Fix a Computer for Its Pixelated Pictures
Pixels are the colour-changing points of light that create images on your monitor. (yellow pixels image by cico from

Blurry or pixelated images are a real annoyance for computer users. Not only can errant pixels ruin the effect of an on-screen image, but squinting at pixelated images for too long can result in eye strain or a headache. Computer image problems can manifest in a number of ways and have many different causes. Your own pixel issues may be due to one or several of the issues mentioned in this tutorial. Work through the steps until you have found the solution that works for you.

  1. 1

    Adjust your screen resolution. The resolution setting reflects the number of pixels that can be displayed on your monitor at a time. If the resolution setting is too high or too low, this can result in poor image quality. This is particularly true if you are using old software, especially outdated video games. Within your computer's control panel, try different resolution settings until you find the one that best suits your monitor. (The location of these settings will differ depending on what operating system you are using.)

  2. 2

    Adjust the resolution settings within your software programs. Media-heavy programs, such as media players or computer games, often have resolution settings within the "Options" or "Settings" menu. Setting the program to match the resolution of your monitor can result in a much cleaner image.

  3. 3

    Update the drivers for your video card. A video card is the hardware component that controls all visual output for your computer. The drivers are the software programs that make the card able to communicate with the rest of the computer. Out-of-date drivers can result in less-than-optimal performance for your video card. To update your video card, download the software from the website for the card's manufacturer. It is also likely that your operating system has a built-in function for scanning for driver updates. There is also the possibility that the video card itself is out of date, in which case it will need to be replaced.

  4. 4

    Turn your monitor off, count to 10 and turn it back on again. This very simple fix is a good cure for stuck pixels -- little dots of light that get stuck in a particular colour, rather than changing with the rest of the image. If the pixels are red, green or blue, then a quick monitor reset should do the trick. However, if the pixels are black and refuse to change colour, it is likely you are seeing a dead pixel, which is typically a result of a broken or worn-out monitor. If you have dead pixels, it is probably time to start looking for a replacement monitor.
