Here's something interesting...
After re-reading the Press Release, I noticed that it says the LW6500 (47", 55", 65") and the LW5600 (47", 55") use the LG Cinema 3D polarized glasses and have LED local dimming, but don't use the Nano LED screen.
But the LW7700 (47" 55") and LW9500 (55" 60") do use the Nano LED screen and have 3D, but it doesn't say if it uses the active shutter glasses or the newer polarized glasses.
Lastly, the LZ9700 (72") is the biggest of the bunch, but lacks the Nano LED and uses the local dimming. Also has 3G, but still doesn't say what type of glasses.
So at this point I'd like to know what type of glasses (shutter or polarized) the LW7700/LW9500/LZ9700 uses. If they in-fact are active shutter, then does that, combined with the Nano LED, make a better image than the LW6500/LW5600 with the polarized glasses.
