As a videophile myself it is very frustrating to walk into a TV showroom
and see the differences between sets. The manufacturers crank up the
contrast and purposefully set the default whitepoint to something
ridiculous like 9300K in order to make their set stand out from the other.
Not only is this unattractive, but it dramaticly reduces the life of the
display (certainly increasing the rate of drift). There are several DVD's
on the market (Avia, Video Esentials) that are similar to many
non-instrumented monitor calibration programs. Obviously getting an ISF
technician to come and calibrate your television is ideal, but in a pinch
these products work pretty well. I'd love to see a more automated
calibration procedure (that is less subjective and instrumented) with a
"cheap" instrument (the gear ISF technicians use is pretty pricey). NTSC
standards, when used, provide a pretty good viewing experience...and it is
really the only thing we have! I know this is starting to get out of the
realm of ColorSync, but I find the parallels interesting.
