hiya Ufo,

i am still learning the basics about calibration, so didnt want to comment on the spectral comparison until i know a bit more of the concepts involved.

in particular, since it is the backlight that determines the overall brightness with lcd screens, how is it possible the peak luminescence of that new JS 2015 samsung series is below a non-HDR QD panel from 2013 ? i suspect the peak hight therefore has some different meaning, yet since it represents a 6500K spectrum it would logically suggests it could be luminescence (and our w900a's are known to have a very vivid red, which would fit). the wideness of the RGB peaks has to do with purity of each color. so the cleaner the peaks the better (and the more precise each peak aligns with the individual R G B frequencies the better)

The cadmium is safely sealed inside the W9 correct? We're all not going to turn into the hulk in a few years, right?
