If your laptop is stationary, can you connect a $100 monitor to it? My ex has a Mac Air with an effed up screen and a 24’’ monitor which works just fine.
Yes, you can use a remote monitor.
I don’t know how it works with Apple products but when my screen went belly up on my HP laptop, I used my 22” PC monitor.
HP has a simple button to go back and forth from the laptop screen to the remote one, and of course a receptacle designed to plug one in.
Google it, I think you find a solution.
