Bob,
I agree with you ... I don't like LCD monitors ... I don't think they 
are acceptable as grading monitors. And not only because of their
poor black levels. There are issues with vision angles, color temperature,
gamma ramping, ...
 
I didn't mean we should be showing DPs and directors the printouts of very 
precise measurements and saying, "Who are you going to believe, ..." 
 
We all hear and say "The blacks look too milky" ... and they probably are. 
We know they are !!! ... A colorimeter or a spectrophotometer will only 
confirm that .... and then tell us much more if a complete CIE XYZ or CIE 
L*u*v* profile is generated and compared to the video standards profiles.
 
What I want to see is these video gear vendors showing us the precise 
measurements when showing their products, and try to convince us this
way that their monitors are indeed acceptable grading monitors, instead 
of simply trying to trick our eyes turning on and off lights in the demo 
room.
 
The perception issue lies behind a color science issue ... and there are
tools available out there ... and vendors have access to them !!!
 
It is a frigging nightmare ... and I agree with Mike Most when he says
he'd prefer to se a better LCD HD monitor before a new 4K one not
usable for grading.
