I don't know the solution, but you obviously need to give us more information, like:
1. is this a graphical or a console app?
2. how did you try to install VNC, what's happened exactly?
3. why don't you try to upgrade that debian?
4. what is running on that "another" system?

If this system is using x, just use xrandr, run xrandr --help for more info. This should also help https://wiki.archlinux.org/index.php/xrandr

To make it easier, install LXrandR or Arandr, both of these are gui front-ends to xrandr.

Let us know if this works.
