I thought 3D was better on the Panasonic DX902 (using cheap Samsung glasses), maybe because its twice as bright as OLED
Plus faking 120fps by forcing 3D in games worked on the Panasonic, but stutters on an E6.
Maybe manufacturers decided the easiest way get more nitts was to remove the 3D polarising filter from a panel, considering the poor uptake in 3D by the public.
Plus Samsung put the LED's along the bottom to eek out 1400 nitts from an edgelit. Thereby destroying the cinema black bar, so does this mean the JS range which can play movies better & has 3D is better than the KS & QLED
I'm guessing Samsung have abandoned FALD for the same reason I returned 2x DX902... because the HDR brightness which gave instant high long lasting nitts also showed up all the flaws in the LCD, plus trailing LED matrix lights.
