 I am using a samsung 32" TV through its HDMI port:

 because I use a laptop which monitor is broken to access the Internet
and also out of convenience (a larger monitor).

 The problem is that after suspending the machine, when I reactivate
it, the display output doesn't go to the monitor and after I close the
broken display of the laptop the monitor either awakens to a black
background or initially shows some orange and pink stripes on a green
background.

 As I did with the other display I had, I have disabled all kinds of
power management options, set up that monitor as the primary output
... to no avail.

 How can I make that kind of setup awaken back into the samsung monitor?

I think this should help
xrandr --output HDMI1 --auto

 For whatever reason it is not clear from the output of the commandd
that I am indeed using a SAMSUNG LCD Monitor connected to one of its
HDMI ports:

I think running 'xrandr' without any arguments shows the available
outputs, but I believe you're on the right track.
