monitor works different then tv output - I think on the VGA/DVI outputs
there is a sense key to check if something is attached.

try then reading the manuals for the driver

man nvidia or man nv

I don't have it installed here on my system, but my father has it and
recently I configured it. unfortunately I didn't pay attention to the TV
output as he is not using it.
But from my experience with intel card you should define the output in your
xorg.conf.

there seems to be a utility called nvtv

http://sourceforge.net/projects/nv-tv-out

about xorg.conf with TV I googled fast and found this which gives an idea

http://www.linuxforums.org/forum/suse-linux-help/43764-nvidia-tv-out-config.html

I'm using

Section "Device"
        Identifier      "Intel Corporation Mobile 945GM/GMS, 943/940GML
Express Integrated Graphics Controller"
        Driver          "intel"
        BusID           "PCI:0:2:0"
#       VideoRam        512000  # Obsolate
#
        Option          "monitor-VGA" "PHL"
        Option          "monitor-LVDS" "DLCD"
#
  Option      "MonitorLayout" "LVDS,VGA"
  Option      "EnableMonitor" "LVDS,VGA"
  Option      "ForceMonitors" "LVDS,VGA"

....
....
EndSection

I would use for TV


Section "Device"
        Identifier      "Intel Corporation Mobile 945GM/GMS, 943/940GML
Express Integrated Graphics Controller"
        Driver          "intel"
        BusID           "PCI:0:2:0"
#       VideoRam        512000  # Obsolate
#
        Option          "monitor-TV" "TV"
        Option          "monitor-LVDS" "DLCD"
#
  Option      "MonitorLayout" "LVDS,TV"
  Option      "EnableMonitor" "LVDS,TV"
  Option      "ForceMonitors" "LVDS,TV"

....
....
EndSection

and setup a corresponding monitor section

Section "Monitor"
#  DisplaySize  376 301
  HorizSync    30-90
  Identifier   "TV"
  ModelName    "800X600@70HZ"
  VendorName   "TV Vendor"
  VertRefresh  58-72
  UseModes     "Modes[0]"
EndSection

and modes if necessary ... but I never did use it recently
