Graphics driver card is faulty or compared
Driver is software that helps the operating system communicate with the hardware. If the screen card driver is faulty, too old or not compatible with the operating system, the screen may appear flashy, cross- striped or unstable display. This is the most common cause, especially after upgrading to Windows.
Inappropriate scanning frequency and resolution
If the screen is installed with a very high speed of refreshment or resolution, which is not compatible with the hardware, it will easily cause blinking or blinking. This often happens when users manually edit display parameters incorrectly.
Screen signal cables are loose or broken
Cable connecting from the motherboat to the screen can become loose, folded or broken underground due to collision, falling or long-term use. A common manifestation is a blinking screen when changing the folding angle or having unusual streaks.
Unstable power source
Weak power source, inadequate power outage or interruption can also cause the screen to operate unstably, easily causing flashing or stripping when the machine is operating at high performance.
Confliction software or application
Some software (especially graphics applications, video editing or security software) can conflict with the screen controller, causing the screen to continuously acknowledge and flake while running.
hardware is faulty
If the laptop screen falls, hits hard or has been used for too long, the internal components such as the panel, screen card (VGA) or control board may be damaged. This is a more serious error and often requires technical intervention to fix or replace it.
When to bring the machine for inspection?
If you have tried basic measures such as driver updates, scanning frequency adjustments, and remove the suspected software but the error has not been fixed, then it is very likely that the laptop is having a hardware error. In that case, you should take the device to a warranty center or a reputable repair facility to check the display cable, graphics card or home screen.
