Hmmm. I would never spend a significant amount of money on a HD display and
not have it calibrated. Neither would anyone I know. The question is
whether you have a third party do it - likely one who uses Colorfacts, the
industry standard software for ISF calibration - or do it yourself with the
"detuned" SpyderTV software or the very basic Video Essentials disk. It's
broadly understood by any audio/videophile that displays are factory
calibrated for the brightly lit, showroom floor and not for actual "theatre"
use.

That which I have read thus far states that NTSC and PAL are in fact
references to colour spaces, albeit most often incorrectly applied to
describe the resolution of the broadcast standards applied in the US and
Europe respectively.
