After an interesting read about the inner working of xrandr I started
reading the manpage.
Got the version of my xrandr and got further info about my system.
And then I was lost in a swell of info and possibilities.

My problem with monitors is following:
I am using as my main monitor a Philips 196V3L, 18,5" 13766x768.
For movies and such I would like to use my television set with a bigger screen
via HDMI. The TV has one HDMI plug which is connected with a box from the TV
provider. If I disconnect the tv from the tv box and plug it in on my
motherboard I can use HDMI as my second monitor. That is not feasible for
daily use.
I found myself a HDMI cable with one HDMI connector and on the other end
three colored (green, blue and red) video plugs.
When I plug this cable into the HDMI plug of the motherboard and the three
colored video plugs int the TV set I expected to receive a signal on the TV
set. The television set is only showing the input "component" with these three
plugs inserted.

With xrandr I read HDMI-1 and -2 disconnected. Also DP1 and 2 are not
How can I force a connection with the HDMI cable and would that change
