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
I realize your predicament, try this... I'd about given up, hope of finding a way, but fingers crossed...
OS X: Use a Keyboard Shortcut for Display Mirroring
Aug 31st, 2016 9:35 AM EDT | Quick Tip
I use an external monitor with my laptop, and if you do too, there’s a keyboard shortcut you should learn—Command-F1. This nifty little combo will turn display mirroring off and on, so if you need to temporarily see your Dock or your open windows on both displays, it’ll let you do that. This is just a quick way to, well, mirror the functionality of System Preferences > Displays > Arrangement > Mirror Displays.

I’m not sure what you mean by safe mode. I tried your holding shift key suggestion but it doesn’t seem to have done anything.
The issue is that I can’t use the laptop without it being linked to the TV because the macbook screen is just all black so I can’t change the settings back, unless there’s a keyboard shortcut to somehow reset the display settings?
Safe Boot from the HD, (holding Shift key down at bootup), does the problem occur in Safe Mode?
If so you should be able to set a workable rez or setting?
😭😭😭😭 it worked!!!! What can I do to repay you haha? You just saved me about £1000
Super, great news... both ours happiness is plenty of reward! 😃😅
