Your LCD screen is composed of pixels and sometimes a few of these will appear dead. When this happens, that area of the image will not be seen. Though this may be a minor problem, it is quite an irritating one, especially if the pixel area is in the middle of the monitor.
Dead pixels can be fixed in a few easy steps. The first thing that you have to do is to identify the problem area. There are many who try to fix the pixels in their LCD screens right away by tapping it with the end of their finger or covering their hand with a piece of cloth to exert pressure onto the area. Though an LCD screen will react and the pixels may be fixed because of the slight pressure it received, fixing your LCD monitor in this manner is not recommended. This is a hardware problem that needs to be dealt with in a systematic manner.
Accessing an online tool to detect exactly what part of the LCD screen is damaged, would be the proper way to identify the problem instead of using your untrained eye. There may be some pixels that you cannot see and these will also be detected by such a tool. Depending on what kind of operating system (OS) you are working with, you can find the right kind of software to actually repair the pixels in a few easy clicks.
Any computer hardware program is to be repaired immediately upon it being noticed before the problem gets bigger. Even if you have heard many positive comments about applying pressure methods to fix LCD pixel problems, the only way that it should be done is with the correct software tools. With proper troubleshooting and maintenance, your computer will serve you better for a longer period of time.
