Why has my xbox one suddenly got a thin green line at the top of my screen?

[WPCentral Question]

When i switched on the console there was a thin green line at the top of the screen on the home page. This has never happened before and i have'nt altered any of the display settings. Any help would be most appreciated.

Have you removed and plugged back in (reseated) the HDMI cable? Does it do it during games or other media? It is just on the home screen?

Mine has the same issue. Anyone have a fix?
