[Tig] what are we going to do (monitors)

[Dave Corbitt]

If you get yourselves issues of Home Theater Magazine, you will see the 
kind of color science reporting Daniel is talking about. Each display 
device they review is gone over and measured for black level, white 
level, and CIE coordinates for RGB primaries and compared to SMPTE Spec 
or REC 709. Granted, these are consumer devices but you would be 
impressed at how good and how bad some of them are and how 
scientifically correct the measurement techniques are. We could all 
learn some lessons from what is going on in informed consumer circles.
