After reading this article you will be able to solve the problem where corruption occurs on your screen or you see lines across your computer display. This problem might occur due to a Display driver problem, a display hardware error, Display connection cable problem or even a faulty display.

If This does not solve your issue,

For Desktop Computer Systems

  • If you have a Add-on Graphics Adapter Installed, try pulling it out and checking the display on your on-board display option. If you do not have a motherboard with a on-board display, get another card to check if that works or try reseating your present graphics adapter properly into the slot.
  • Check the Display Cable ( Any type ) for damage. Also check both ends of the cable to make sure they are properly plugged in.
  • Check your Display Monitor with another computer of laptop device to make sure you don’t have a problem with your Display.
  • You can alternatively try to plug another monitor into your computer to check if that works properly.

For Laptop ( All portable Computers )

  • Take out your laptop battery, press & hold your power button for a few seconds.
  • Reinsert the battery into the compartment & check if the problem persists.
  • If your laptop shows lines across the screen when you move the display panel ( move the hinges to adjust the display ) then your cable connecting your display to motherboard/display adapter might be wearing out, in this case the only recommended solution is to take the computer to a authorized dealership or support outlet.


  • Your Computer monitor might display some lines across the screen if there is a power surge or when the power input is lower or higher than the recommended range your monitor supports (Most of the time LOWER ), Check the documentation that came with your monitor to confirm the recommended power input.
