Display mirroring not working
My macbook display LCD is broken so i’ve been mirroring the display onto a TV with a HDMI cable for a while now. Today it started goofing so I checked out the scaling(?) slider in System Preferences and must’ve clicked something wrong and now all it displays is an apple wallpaper, no login access or apple toolbar, just a plain old sand dune stock photo in the middle of my TV. Help pls 😩
MacBook, macOS 10.14
