It is to adjust the screen to extremely black and white, allowing you to observe whether there are bright spots on the TV, check for any color blocks or damaged light strips, and check the quality control and interface sealing of the TV 2. Gray scale test and clarity test, which will provide a set of numbers for you to view the range of numbers that can be seen when your screen is weakest or strongest, similar to the principle of a vision test chart

If the previous screen does not immediately disappear and the visual effect appears at the same time as the second screen, there is a residual image.

As shown in the following figure: If the screen has a hazy display grid, there may be residual issues
