Can you use an Android mobile phone as a monitor?

Since I couldn't find anything on Google, I'll try it here:

Everyone knows that you can transfer the screen from your cell phone to other devices via cable, but also wirelessly. But I want to know if / how you can do the whole thing the other way around.

So that you e.g. Connect a PlayStation or Bluray player via HDMI (or wireless) to the mobile phone and the content is then displayed on the mobile phone.

You can connect your mobile phone with an hdmi cable. You need an adapter on the cell phone

I do not want to transfer the screen of my mobile phone, I'm wondering whether it is possible to transfer the display from other devices to the mobile phone or how it works.

I don't mean that. For example, I want to connect a PlayStation, Switch or BR player to the tablet / mobile phone…

DOES NOT work because your smartphone does not have a video input.

NO smartphone has a video input. They all only have exits.

Oh, thank you, I just wanted to know
