2014 Sony W950B Black: 0.111 cd/m2 Contrast: 942 : 1 >>>> LGD IPS
Notes : AUO AMVA and Samsung SPVA are both VA panels LGD are S-IPS

All 3D Samsung are active .
All 3D LGD are passive .
OFC when the Sony 9x and especially the TOTL 9.5x cranks up it's bag of magic silicon tricks they have remarkable picture. 9.5 x is widely regarded as the best 2014 LCD
The 2014 W600/2013 R4 black levels are almost same contrast while still good are a little behind the 2013 R4
The 2014 Sony W800B and W850B are similar to 2013 R4 black level and contrast
Sony W950B black level/contrast being an LGD S-IPS do not match the others for native contrast /min black levels
It would seem the Sony W800/850B would be the sweet spot at Sony with respect to price vs performance
