Michael came home and I told him about my malfunctioning monitor. He went to my desk, had a look, and pressed a button on the underside right corner. Poof! I could see the desktop again. It would seem that all this time my monitor was “not working”, it was merely turned off.
I admit I hadn’t checked that, simply because it didn’t occur to me that simply clicking on a YouTube video would somehow make a monitor turn itself off. How that happened is a mystery to me.
But my computer is working again, and I feel like an idiot.
