using DESKTOP-CMP8AOC as a monitor to split screen from work laptop. there is no HDMI button

[Dannyc1]

how do I get HP 27 desktop DESKTOP-CMP8AOC, to become a monitor using HDMI cable for laptop. (required by work to use the laptop).

From the other threads I have read it should automatically detect, but this does not happen. also there is no HDMI selection button as I have seen on other threads.

There are many possibilities
the computer has an HDMI output and / or input
Or just an HDMI output!
If this does not generally work, it is because the computer has just an HDMI output not an input
