First of all, the specs you may have been through, not a single flaw in the specs. True 200Hz refresh rate which is maximum in any of the existing TV mnodels out there. The numbers Dynamic MCI 800 in LG or MotionFlow XR 800 in Sony is nothing but an index that the companies give from their side and these indices are not in Hz. Actual frequencies are normally 200Hz for index above 600 and 100Hz for indices above 400.
Regarding 3D mode, Active 3D is conventional (1st generation 3d models had this technology) and is better ONLY if the frequency of the TV is maximum in terms of refresh rate as it uses the concept of flickering which may cause headaches in case the frequency of the TV is less. Passive 3D in terms of 3D quality is head to head with the Active 3D method and other aspects like comfort, price, weight of glasses are ruled by the Passive 3D over the Active 3D. Image is much more brighter in Passive 3D as compared to Active 3D and crosstalk is nil in case of Passive 3D. Overall | will say Passive 3D TV at home gives the best 3D experience. Its the best when the distance between viewer and the TV is in the range 1Oft-12ft. LG provides 4 basic 3D glasses with purchase. Dual Play glasses are expensive and need to be purchased separately.
Coming to TV, the tv is a complete package of features you may dream to have present in the TV. From IPS panel to 3D Dual Play feature, everything is present. Image quality is super. I purchased it a week ago from an offline retailer at Rs.85000/- that too with 0% EMI.
