Horizontal Lines on the bottom of my Mac Air
I have about 9 very small horizontal lines at the bottom of my screen, how do I get rid of them, I've already tried restarting with Command, Option, R & P, and I've restarted holding down the D button, but the lines are still here, tried to do a print screen and they don't show up on that, so I took a picture with my Ipad and drew a line to the lines that I can't get rid of. Any help would be greatly appreciate.
MacBook Pro 15″, macOS 11.2
