When I'm at the studio I connect my Macbook Pro to a 42" LCD 1080p HDTV using a HDMI cable (don't use a VGA). I use it as a second monitor for editing and then I also use the same setup during client proofing appointments.
I've used this setup on 4 different HDTV models and never had a problem. However, most HDTVs will not let you adjust color settings when you are connecting via VGA but use a HDMI cable and it should unlock the menu so you can tweak the TVs colors .. if you need to at all that is .. Mine are all actually dead on accurate right out of the box ... 99% of my photography goes out to the client as a physical product and the HDTV colors are dead on with everything I get from both Millers & H&H Labs.
and come on .. it's 42 inches of love for only $400 .. you can't beat that LOL :P
