There are many main reasons why laptop screen flickers continuously

Some of the top reasons why the laptop screen is constantly jerking can be mentioned as follows:

1.1. The application is not compatible with the laptop screen

Each person's laptop is installed with many different applications and programs. In many cases, the graphics settings of some applications may not be compatible with the laptop, resulting in the laptop screen jerking or flickering continuously.

To find out if an incompatible application is the reason why your laptop screen is stuttering, follow these steps:

Step 1. Click CTRL + ALT + DEL and select Task Manager .

Step 2: In the new window that is displayed, see if the laptop screen is flickering or jerking. If everything on the laptop screen is flickering or jerking except for the Task Manager window, there is definitely an incompatible application on the computer.

Step 3. If the Task Manager window is also flickering or jerking, it's likely that your computer is having some other problem.

1.2. Driver of laptop video card is old

If only certain folded corners of the laptop screen flicker or jitter, and others do not, the cause of this phenomenon is a faulty internal wiring. Furthermore, a loose or damaged inverter, display or backlight cable can also be the cause of this error.
