I'm not familiar with the TV you're using, but I can say a few
things that are broadly true of a wide range of HDTVs that support
stereo that may also apply in your case.
If a TV has a DVI input (unlikely), then one is sometimes able to use it
just like any other stereo display.
If the TV uses HDMI, then the options for stereo will depend
somewhat on which operating system the computer is running what
video card, and what driver are being used.
In regards to the NVIDIA GPUs, the "Quadro" GPUs have the best support
for stereoscopic display across all OS platforms. Last I knew however,
HDTVs are considered a special case, and at least on the Windows platform
there was/is a special driver that one had to use to allow stereoscopic
display to an HDTV over HDMI (3DTV Play) for games and the like:
I just looked up the NVIDIA web site regarding stereoscopic display,
and they have clearly rewritten much of it since the last time I looked:
I would expect that the Quadro would have a good chance of working with
a 3D HDTV, but you will likely have to set the NVIDIA driver's stereo
mode to one that your TV agrees with. If you tell me which OS
you're running, we can work through a few of the details there.
The most important thing is to see if VMD lists "STEREO" during the
OpenGL feature startup messages that it prints to the text console.
