Question Green verticle lines

[Suraj_289]

I recently noticed green verticle lines that flicker across my whole screen. My monitor is a hp 22x gaming display. What can I do to fix this? I don't think it has anything to do with my pc because when I unplug my home cable they are still there

when I unplug my home cable

what is a "home" cable?
you mean HDMI or Display Port cables?

if these lines continue when nothing's connected i doubt there's anything you can do.
if it's still under warranty, contact support about RMA.
