Many thanks, Ned,
Great, the works. Now the display is in the center / the middle of the TV screen and not displaced anymore, but it is still framed by the black bars / space. I can change the size, make the display bigger, so that the black bars become very small when I set a lower resolution:

I remember, I have on the other Notebook, 1, 2 years before used such a programm to fit the display for the graphic card or so...on the Notebook now, I have Nvidia and Intel show to be the graphic cards? 2 ones? Can the be true?
Or would it be better to use XBMC - if possible at all - to fit the display?
The graphic card (or one of them):

There the other graphic is shown, obviously:

Sorry for the lack of information, I use the head phones / line out plug of the Notebook for the sound to that ampflifier. I had copied my portable XBMC to the other Notebook, so I had thought the settings would be overtaken / right. I use the head phones plug there, also.
