Two lines appeared on my MacBook Pro screen after tilting it to plug in

I was working on my MacBook Pro, typed it sidewise to enable me to plug it in and two lines came on to the viewing area on the desktop. I've rebooted, they are still there. Any suggestions?

You can take a screen shot and see if the line are embedded there(?) this would indicate GPU


if no lines it indicated Display hardware issue— you can use an external monitor as a work-a-round


In or out of warranty you can get a free over the counter 'Apple Service Diagnostics' test /assessment
