I've posted this video before (
http://www.youtube.com/watch?v=ji2265tHCVs). This is an explanation of the nano tech from last year. If it's true that LG has improved the nano tech for this years TVs then there is no way they can keep a set up like the one in the video, with only 24 zones.
I have heard 3 figures for dimming zones.
1. Very low 24 zones: Personally I think this might be a miscommunication. I don't see any reason why LG would make their "flagship TV" have only 24 zones. Also this would create an insane amount of blooming. I personally think it's more probable that the LG TV's equiped with "LED Plus" (LM8600, LM7600 ect.) have 24 dimming zones as they are edge lit.
2. 96 Zones: This could be right.
3. More zones than last year: This is what LG reps told people at CES. I think this is probably the truth.
At the end of the day, no one really seems to know
for sure how many dimming zones this TV has. Also LG as a business would be stupid to reveal how many dimming zones this TV has.
So far, reviews for this TV have been great. Every review has praised this TV's black levels, color, and overall PQ.
I think we all need to remember that there is no such thing as a perfect TV (yet). We shouldn't write off the LM9600 until we see it in person. IMO the 9600 is the best flagship this year (and I'm a Samsung fan).
