How to check the monitor for dead pixels
It is also important to understand how a stuck pixel differs from a broken one. In order not to go into technical details, I will simplify everything to the maximum.
A stuck pixel will be displayed in one of three RGB colors: red, green, or blue. If even one color works, there is a chance to fix the pixel.
The broken one will not be displayed in any of the colors, that is, it will be black. And you won't be able to revive such a pixel.
What programs can not show
None of the programs will be able to show a dead pixel. That is, you yourself will have to look for the problem with your eyes, it is physically impossible to highlight it on the monitor.

A dead pixel is a picture element in which all three RGB (red, green, blue) sub-pixels are permanently turned off, which creates a black spot in the display.
Malfunctioning transistors and manufacturing flaws can result in dead pixels. Dead pixels are often confused with stuck pixels, which have a different cause and effect. Each pixel in a display is made up of three sub-pixels: one red, one green and one blue. In a stuck pixel, one or more of the three remains turned on so that the pixel displays consistently as a particular color rather than refreshing along with other display content.
Depending on their number and position on the screen, dead and/or stuck pixels can impact the user experience. Both dead pixels and stuck pixels have been reported to disappear (and sometimes reappear) over time.
