Generally speaking, there are two main possibilities for this phenomenon.
The first case is the most common one. The currently set resolution is not the best resolution of the display, which leads to the pixel being stretched and enlarged for display, resulting in a relatively vague ghosting phenomenon. Moreover, if the resolution is too large or too small, the content displayed on the screen will be relatively enlarged or reduced.
In addition, it is not excluded that the LCD screen is stuck (note: the LCD screen itself will also have this problem, including early CRT monitors).
Reminder: In some humid areas, due to the influence of the environment, there will be "abnormal" phenomena such as ghosting, twill and water mist on the screen, which are uncontrollable factors of spare parts. It is suggested to improve the use environment.
