I have a notebook that I connect to my school beamer with a HDMI cable.
In Trinity Control Center I can see both my laptop screen and the HDMI screen. I cannot use it if I don't "extend the desktop" to it, but then all my apps open stretched overt the two and control is very difficult.
I can set the external screen to the same resolution as the internal, but there is no option to just mirror the internal screen on the external.
Am I missing some black magic?

xrandr --output HDMI1 --same-as LVDS1
change the names of outputs according to what xrandr shows.

From my experience to use different resolution when extending screen, you may need to use "scale" option of xrandr. Most probably you have intel - if more sophisticated card, it might be other way possible too.

What does 'inxi -Gxx' in Konsole opened by a virgin user report? Is it the same as when run by your regular user?

What exactly do you mean by "virgin user"? Should I create a new user to test this?

A user who has made no settings customizations.

New user method is generally sufficient to create a virgin user. A previously created user can work if its ~/.kde/, ~/.trinity/, ~/.local/ and ~/.config/ have been purged.
