One thing I have learned is that Dell (and other places, I'm sure) uses
OEM packs of the Quadro cards. If you are getting the K4000 or K5000
variety, as in my case, they don't include a critical additional bracket
that comes with the retail pack (from PNY). The use of nVidia's Vision
system is impossible without that, and PNY won't sell you one. The tech
support is from outer space when doing 3D, as you point out.
Pays to carefully research the details...

Both the Vision Pro and Vision 2 systems are active. The gamer version
is IR, the Pro is RF. Either can work in a crowded room, even the IR if
you are careful about placement. The IR can be attenuated.
I haven't seen anything saying the cards don't work with passive
systems. I believe nVidia supports a number of approaches to 3D, not
just their own system approach.

I see conflicting opinions coming from the TV industry. Sony apparently
is working hard to sell their 4K sets despite dire predictions about the
state of 3D. Samsung seems to be well in it, too. I think it comes
down to the lag in content and quality.
** Something about what Greg pointed to... using HDMI 1.4 causes a
slowdown in frame rate to 24 fps due to hardware issues because of the
standard. V2.0 basically ups the data rate to where you can get 60 fps,
and what little I have seen asserts this is a hardware (not cable)
limitation. V2.0 is supposed to be backwards compatible.
Since Quadro cards like the K4/5000 use a simple after-card DVI-I to
HDMI cable adapter, I am curious whether the card's output is up to the
level of v2.0. I haven't checked other cards. Guess we have to wait
for someone to plug their 3D PC into their v2.0 home theater system to

In a completely rational society, the best of us would aspire to be
*teachers* and the rest of us would have to settle for something less,
because passing civilization along from one generation to the next
ought to be the highest honor and the highest responsibility anyone
could have. - Lee Iacocca
