Hi everyone,
My computer monitor has recently started showing static lines across the screen. The lines remain visible even after restarting the PC, and I’m not sure whether the issue is caused by the monitor itself, the display cable, or the graphics hardware.
Any suggestions or experiences would be really helpful. Thanks in advance!
Some time ago, I assisted a friend in fixing an LCD monitor that developed horizontal lines on the screen before they purchased another one. They were convinced the monitor was defective, but we started checking through the quick fixes (i.e.: Checking that both ends of the cable were connected) and upon checking the HDMI cable between the monitor and the computer, it was discovered that the HD-Mi cable was loose since their desk was recently rearranged. Once that Cable was secured, the lines vanished.
For this reason alone I recommend starting with simple fixes first. Check cable connections, reboot the computer and if possible, test another monitor with the same video Card and see if it works fine. If there were any issues with each fix, then it is worth pursuing driver and/or damage to the video card. Sometimes the simplest problem, turns out to be the cause of the overall problem.
I will start with a few basic checks before assuming the monitor is faulty.
– Try a different HDMI or DisplayPort cable.
– Connect the monitor to another PC or laptop.
– Update or reinstall your graphics driver.
– Check if the lines appear even during startup or in the BIOS screen.
If the lines are still there on another device, the monitor panel is probably failing. If they only appear on your current PC, I will look at the graphics card or display port first.
