faint horizontal lines across my monitor

Thin lines show up across the whole screen, more visible on dark backgrounds. Swapped the HDMI cable and they're still there. Is the monitor on its way out or could it be the graphics card?

Open the monitor's own on-screen menu with its buttons and look at it. If the lines are drawn over the menu too, it's the panel itself and no setting on the PC will fix it. If the menu looks clean, it's the signal. Reseat the cable at both ends, try a different cable (cheap HDMI cables cause exactly this), and check the refresh rate in Display settings > Advanced display is one the monitor actually supports.
