Screen refresh rate is not compatible with computer
Screen refresh rate is the speed at which the screen displays images in one second. If the screen refresh rate is high and set to an inappropriate mode, it will cause image flickering even without any action.
Video card not working
The video card is a part that processes information about images and graphics of the computer. If this device is not installed compatible, it will cause errors or reduce quality. This is one of the reasons for poor image quality and jerkiness, causing the laptop screen to flash continuously .
Screen error
The computer screen is an electronic component and has a very high probability of failure. To check if the cause is due to a screen error, you can change the input signal plug. If changing the input signal plug fixes the error, then the other signal plug on the screen is faulty.
