Why Is My Computer Screen Flickering & Shaking

Among the various electronic devices, the computer stands foremost in driving the modern human civilization further up on the scale of development. This can easily be reasoned through the presence of some computer, from micro to supercomputers, in every technical setup nowadays. 

Almost all modern homes will have some kind of a personal computer. However, if a machine as complex as modern computers starts giving some issues, it can be a challenging task to decipher the exact cause behind its malfunction. Among all these, issues like when your computer screen is flickering are relatively easier to approach and resolve. The upcoming sections will talk about how the flickering of the computer screen can be fixed.

Why Is My Computer Screen Flickering?

A computer's screen can flicker mainly for two reasons, software or a hardware glitch, and it's easy to figure out which one is in your hands. A hardware issue primarily relates to the screen itself, the physical graphic card/controller, or the connectors and cables. Software glitches are usually due to faulty or obsolete graphic drivers. The given steps can be taken up to get to the cause of this problem and rectify it:

  • First, check the screen and rule out the possibility of any faulty hardware. If your computer is a desktop, check the cables and other connectors. Take these cables out and rejoin them to the screen.

  • If one has a spare screen, connect the screen to your desktop/ laptop and check the performance of this screen. This would indicate if something is wrong with your original screen or not.

  •  If you already have an extra screen connected to your computer, disconnect it and check how the original screen is working. An additional visual load can disrupt the computer's performance to provide smooth visual output.

What To Do When Your Computer Screen Is Blinking

If one has tried all these steps and, still, the computer screen is blinking, then the display software has to be checked now.

  • One can adjust the screen refresh rate before attempting to troubleshoot the actual display software. The refresh rate is the number of pictures per second the screen makes to give a congruent display.

  • Click on "Start" and then choose "Settings." Next, hit on "System" and then go under "Display" to get to the "Advanced Display Settings."

  • The "Refresh rate" option will be mentioned here. The general refresh rate for a PC is 60 hertz, and you can choose this display rate or a higher one in steps of 20 hertz if 60 is already selected. Next, check if the screen is blinking anymore or not.

  • If the screen doesn't work correctly, start your computer in safe mode and right-click on the Start menu. Next, choose "Device manager."

  • Click on the "Display adapters" section and select "Uninstall device." After this, restart the PC to reinstall the drivers and check the screen.

If the display on the computer screen is shaking even now, it points to a deeper issue for which the help of a computer technician is required. You can contact the best computer repair technicians near you to get this concern resolved.
