How to get a HDMI-conection to life, without rebooting

when Linux boots, in my case Debian 9, it finds the available hardware and loads firmware/software accordingly.
my machine is connected with HDMI to my TV.
when this TV is off, or using another HDMI connection, Linux sees the connection as dead.
so, nothing is loaded.
when later the HDMI channel for the Linux machine is selected, it simply is not working.

how can I get this connection working, without rebooting ??

by manually loading firmware/software accordingly?

without more detail, i can only quote this back at you.

ok, thanks
what more detail would you want ??
the machine is a Compulab Fitlet2, also know as Mint MiniBox 2
this comes normally with Linux MInt installed, but I went for Debian 9 instead.

might running modprobe mean something ??

I do wonder if that could be set up for hot pluging like a USB Port via polkit. That might be worth taking a gander at.

in fact, the problem is, that when you reopen an unused HDMI-connection, you first have to show some activity.
when I stop using the HDMI-connection, I always log out of the session.
next time I make a connection, the HDMI-connection comes to life, simply by entering my username and password.
in other words, the connection did not close down, but simply went to sleep.
