Unfortunately, because I'm nosy, he couldn't find out who manufactured my VA panel in the 70x850b but it's Active. I haven't personally ran across a IPS panel that is Active 3d but there's plenty of stuff out there that I haven't seen. FYIW, that 65w950b I installed had a stunning picture and very nice 3d. Better 3d than my Active X model. IMO, if Sony would have taken the r550a display, added the X-Reality Pro Engine and added the TRILUMANUCE color filter they would have ruled the 60"70" market for years. If if if.
X-Reality Pro is very cool. IMO (I'm not in the majority), Triluminos isn't that big of a deal, though it's not just a filter: the filter is ancillary to the more imiportant changing of the light source from a broader dichromatic white to a trichromatic LED or QD white.
Regarding IPS, I think you might be counting on a Sony service rep to be right, and I've found mistakes filter down from reps before. In fact it was a Sony service rep that told my BB guy that all passive 3D screens from Sony were IPS and made by LG
. That turned out to be false.
Reps are just as prone to hearing misinformation and floating them around as fact as any of us are it seems. Don't get me started on the BS from LG reps. Oye.
And again, keep in mind that because it's not actually part of the Sony specification, the underlying panel for any model is free to change even for the same model at any time.
AFAICT, the only ones that were diligent in putting IPS in their TV model specifications were Panasonic and LG.
