Modern technologies are developing very quickly. Every day more and more new and modern models appear on store shelves. Outdated electronics give way to new modern technology. CRT technology is being replaced by liquid crystal displays. Many of us seek to acquire new equipment. After purchasing a new monitor and testing it with games or movies, very often users find a colored dot on the screen. This defect is called a dead pixel..
The image of a liquid crystal monitor consists of dots, which are called pixels. Each pixel is driven by a thin-film transistor that fails and causes a black dot to appear on the screen. Another type of dead pixels are the so-called stuck pixels. They do not react to changing the image on the screen, but glow in a certain color.
When buying, it is very difficult to check the monitor for broken pixels. Managers demonstrate the product with the help of colorful pictures. A broken pixel can only appear on certain colors. You can test your monitor using Nokia Monitor Test. If you are going to buy a monitor, do not be too lazy to burn the program to disk and take it with you to the store.
It is impossible to cure black dead pixels at home, but it is quite possible to fight with color ones. Stuck, colored pixels can be removed with gentle massaging. This is done with a cotton swab with the monitor turned off. If you find a dead pixel using the Nokia Monitor Test program, gently press it with a cotton swab.
After a few minutes, turn on the monitor and check the result. This method does not give a 100% guarantee, but it’s worth a try..
There is also a software way to eliminate dead pixels. Go to www.jscreenfix.com and run the program.
After that, a window with flickering pixels will appear on the screen, which you need to point at the area with a broken pixel and just wait for the result. Usually, 20 minutes is enough to eliminate the defect, but if during this time the dead pixel is still present, run the program for several hours. The work of this program is to change the colors of individual pixels at a high speed. So the stuck pixel is programmatically aligned.
Of course, when dead pixels are found, you can use the warranty on the monitor, but the percentage of such defects is very high, some manufacturers even set a certain standard for the presence of dead pixels..
