What is Pixels & Dead Pixels?
The triple point group the smallest of all digital images is called a pixel. In English the "picture element" which means the picture element is extracted from the combined word. Pixel is the abbreviation of picture (picture) word pix and the word (element) consists of the first two letters (el). The Pixel Turkic is called "Gözek".

We have thousands of pixels in our display devices and we can get images with various colors. However a few of them may be dysfunctional as a result of thousands of pixel factory errors and we call these dysfunctional pixels Dead Pixels. Of course we do not want to get dead-colored devices. For this reason when we receive a device with a screen we must first perform a dead pixel test and if the dead pixel is present the received device must be replaced or returned.

How to Perform a Dead Pixel Test
Dead pixel test is very simple you can reach my test page by clicking the Test button at the bottom. There are 5 different colors in our test page you need to look at these colors in full screen. For example when you are looking at a red color you see a color other than red in any spot on your screen; Your device has dead pixels.

No pixels that are dead pixels are automatically detected in any dead pixel test so you should first be sure to clean your screen and then perform the analysis carefully. If you look at the black screen you can test the cloud at the same time.
