Sounds strange, but is it possible to use the phone as a monitor with the help of adapters? It is the other way around - with a USB-C to HDMI adapter and then connect it to the television - there are in any case many articles about it. But is it the other way around that you can, for example, transfer the Playstation or the computer to the cell phone. So that the cell phone is the HDMI input device

Ja

You can display the phone on the display with an adapter, but not the other way around using the phone as a display.
