[quote=myoda;21731579]Link to the 70, 60, and 52 inch 640U and 6400U series operation manual. Have yet to see a review of this item or pictures of the panel in a real world environment - might head over to Costco to see the LC-70LE6400u. I see that the major differences between the 6400U and the 640U are AquoMotion 240 for the 6400U. Looks like the price is the same for either 70 inch panel at this time. Neither are Quattron panels at this price point. There is now a dedicated Netflix button on the remote, the SmartCentral apps look better, edge lit (hope that eliminates clouding issues), and both sets are lighter than the 632 series - 86 lbs with the TV and stand, 79.4 lbs without the stand.
Last year 60 and 70 inch 632 series had a dynamic contrast ration of 6,000,000 to one. this years 60 and 70 inch 640 series have a 4,000.ooo to one. Any thoughts about this? (picture quality, sharpness effects?)
