Yes, but... for people more than 3 feet away from the screen (ie the
public crowding around) it's sufficient, and an excellent trade off.

Absolutely.  There is one called a "TV-ator" by Antec at Frys that's about
$70-$80 dollars.  

I'll never buy another video card with "direct tv out".  It's just not
worth all the drivers and crappy PC-based configuring you have to do.
TV-ator doesn't care about resolution or refresh rate (although the
picture does change position slightly depending on these).  640x480
through 1024x768 up to 75hz is what I've tested.

Didn't see the original on this, but analog vs digitial into what?  VGA?
I don't know of any digital monitor connection scheme in existance at the
moment, so please enlighten me...  (Just checked it, still no clearer...
If this is a "standard" xVGA type monitor/video card there is no
difference in signalling electronically, they're all analog... anything to
the contrary is marketing hype, or referring to the overloading of the
sync lines for DPMS controls, which are in-spec even for monitors that
don't understand them.)
