Laptop screen stays black after HDMI TV transmission?

Yesterday we watched a movie on the television via HDMI transmission. Then I removed the HDMI cable again, but the laptop screen remained black.

I tried different key combinations with FN key - does not work.

I switched the HDMI cable to the TV again, it transfers everything super to the TV screen, I can use the laptop there, but if I take out the HDMI cable again - the laptop is black.

What can do?

Tried to restart already?

I tried.

I've been sitting here for hours trying different things with HDMI over TV. I can operate the laptop via TV, but when I pull the HDMI cable out again - black.

I tried:

- Windows + P (PC only, duplicate, expand, only 2 screens)

- Extended display settings: adjust display (1,2, or expand)

My laptop is totally new and great. We just transferred a film from laptop to TV yesterday and it's been like that since then.

There's a catch somewhere and I can't figure it out. And Media Markt is closed due to Corona.
