Some outputs aren't turned on unless the card detectes a "monitor" (by
which I mean a display device, SDTV, monitor, HDTV etc) plugged in at
boot time. Also settings in /etc/X11/xorg.conf might restrict X to
what monitors it starts on.

The tool we were referring to is called nvidia-settings, you can run
it from a terminal if you can't figure out which little gimpy icon it
is in the menus :) Simply run a terminal on your X screen and type
nvidia-settings, the programme should then run. It helps a lot in
setting up twinview, multiple X etc etc.

Well in the hierarchy of quality it is at the bottom:

RF
composite
s-video

then you are into component and digital connections like HDMI. The
first three will only do SD, the others will do higher, up to 1080p.

I am not sure what STB's you are referring to. What you need is a
frontend at each TV. Your setup should only use STB's if that is the
only method you have of getting an unencrypted signal, but I think
from another thread you are stuck with an STB because you have
encrypted satellite to contend with.

(STB)<-analogue->(Backend)<-network->(frontend)<-->TV
(STB2)<--analog-->(               )<-network->(frontend2)<-->TV2

That is the ideal setup, I have found some of your earlier posts
difficult to follow because you seemed to be contemplating some other
architecture involving STB's all over the house. You can have as many
STB's and as many frontends as your heart desires, bearing in mind you
reach a point where your network and/or your disk IO gives up the
ghost.
