One of the most common problems that we can find on our monitor is that a small black spot appears. At first it may seem like a dirt stain, but what can really happen is that it has what is called a “dead pixel”. It is something tremendously annoying, and that automatically centers the vision of our eye, especially with content that is very colorful that makes us outline the area where the problem is. To discover if our monitor contains dead pixels, there are some free websites and applications that will help us analyze it and even try to recover them.
We are talking about dead pixels , when it is a pixel that remains on at all times within the LCD screen, thereby causing a defect in the resulting image. We must also know that there are two types of dead pixels and that they differ from each other, depending on the type of color that corresponds. In this way we can talk between the Hot Pixel and the Stuck Pixel.
It is known as Hot Pixel to that unit that has been turned on in white permanently. In case it has been lit by a more solid color, such as blue or red, we speak of the pixel being stuck, which is known by the name of Stuck Pixel . Despite this difference, both dead pixels can be seen with the naked eye on our monitor.
Dead pixels are represented as a black point , and in case it is defective from the factory we will not be able to do anything. On the contrary, if the pixel has remained blank or in a fixed color, it is sometimes possible to repair it by forcing to load sequences of colors that manage to reactivate them.
That is why today we are going to know some web pages and applications that, for free, will allow us and identify if our monitor has dead pixels, and in case they can be saved, they will try to recover it .

Web pages to find dead pixels
Bad Pixel test, perform tests and check the status of your monitor
It is a website where we can check the status of the pixels of any LCD screen or monitor. It allows us to check, by carrying out some tests, what is the response that all the pixels on our monitor have to white, black and other bright colors such as red, blue or green. In case our monitor has a sleeping pixel, it is likely that we can solve it by performing the test several times, although it is not a 100% safe solution. If the test results show that we have a dead pixel it will be due to a manufacturing fault, so there is little we can do other than try to get the warranty.
