   Thanks a lot Paul.   
   The HDMI ports are probably all the same, in the Menu and I can label   
   each HDMI whatever I want.   
   At the moment it is connected with a long unspecified cable, a new one   
   is coming soon. ( I hope ).   
   The profile can be saved, it could not before but that was likely   
   because a Beamer was connected, now that the beamer is disconnected   
   profile saving works.
