Dead pixels are a common problem associated with liquid crystal display (LCD) monitors. They show up as dots on your screen that either always lit up or dark. Constantly lit pixels are called stuck pixels to distinguish them from dead, or constantly dark, pixels.
If you discover dead pixels shortly after removing your monitor from its packaging, you can easily return it as defective, but pixels can suddenly die as time goes by.
There are a few ways to fix this problem using software. They aren't guaranteed to work, but they might be worth a look before you try to get a refund for your monitor.
