My monitor suddenly started showing horizontal lines across the screen. They appear during startup and stay visible even after restarting. I’m not sure if the issue is caused by the monitor, graphics card, or a loose cable connection.

My monitor suddenly started showing horizontal lines across the screen. They appear during startup and stay visible even after restarting. I’m not sure if the issue is caused by the monitor, graphics card, or a loose cable connection.
Horizontal lines on a monitor usually mean your screen is having a hardware mid-life crisis. Before you panic and buy a new one, it’s usually down to two things:
One. Your HDMI or DisplayPort cable might just be loose or giving up on life. Unplug both ends, blow on them for good luck, and push them back in tightly. Better yet, swap it out with a spare cable to see if the lines vanish.
Two. To find out, plug the monitor into a completely different device (like a laptop or a console). If the lines are still there, your monitor is officially cooked and it’s time to go shopping. If the lines disappear, your monitor is fine, but your PC’s graphics card drivers are having a meltdown and need an update.
Try swapping the cable first, it’s a lot cheaper than buying a new display.
