Thin horizontal black lines flicker across the screen, mostly when scrolling or in fast games. 144hz monitor on DisplayPort. Dropping to 120hz seems to make it happen less. Cable, settings, or a failing monitor?

Monitor is covered in red horizontal lines and little red dots, worse when the screen is mostly dark. Tried a different cable and a different PC, still there, so I'm guessing it's the monitor itself. Anything to try before binning it?

Three thin coloured lines appeared on the left side of my gaming laptop screen yesterday. They stay there in the BIOS too, but an external monitor over HDMI looks perfectly clean. Does that point to the panel or ribbon cable, and is it ever fixable without replacing the whole screen?
