This article will explain how to find dead pixels, and what you can do about them once you find out that your custom built PC's monitor does in fact have a dead pixel or pixels. A custom built PC's 1080P monitor or a TV has (by definition) 1900 pixels and 1080 pixels both horizontally and vertically respectively. What that means, is you have about two million little spots of light that make up the image you see through the monitor. If you have a dead pixel, you can have a little black spot that shows up on a colored background.
Now there are other kinds of dead pixels as well, but those are actually technically called stuck pixels. A stuck pixel will potentially show up on your customized desktop PC monitor display as a bright green, blue, or red spot on a colored background. So step one when you get a new monitor or new TV is to find out if you have any dead / stuck pixels. The easiest way to check for dead / stuck pixels is by using a program, which you can download for free. Simply do a Google search for 'dead pixel buddy' and download the small application.
In order to most effectively scan for dead / stuck pixels using this application, you will need to look at the different color options. As soon as you click on any given color it will turn your whole screen that color. This will allow you time to scan all along the monitor and see if there are any bright spots, or dark spots, that show up. This program also has a small built in application where you can time cycle through all of the available different colors and set how long you want the color to show.
So you scan along your monitor on one of the given colors, and you find a dark spot on your new custom built PC's LCD monitor. Bear in mind that you are not going to get a replacement unit from the manufacturer, unless you have multiple dead / stuck pixels, and if they are in the middle of the screen. You might be able to get a return if you have something like four bright red pixels in the middle of the screen, versus having four dark ones on the outer edge of the screen would not allow a return. This is because the second scenario is far less distracting, and dead / stuck pixels are actually considered a normal part of a customized desktop pc monitor or TV. It is not always a disaster if you have a dead / stuck pixel, because a lot of the time they will go away over time whether they are dead or stuck.
To speed up the process of the dead pixel or pixels recovering, sometimes by pressing firmly on the screen (right where the dead pixel is) for about a second, then letting go and repeating the process for about a minute, can actually cause the dead pixel or stuck pixel to come back to life. This works because your customized desktop PC monitor uses a black light along with a liquid crystal solution to display the various different colors. When a pixel becomes dead or stuck, there is very little or sometimes even no liquid crystal within that particular pixel. So by pressing firmly on your screen, essentially all you are doing is distributing the liquid crystal solution from one pixel to another. Now do not worry, there is plenty of this solution, so you will not end up with another dead pixel, and if that happens for whatever reason, you can simply repeat the process and your pixels should in fact, come back to life over time .
