1- In both Tvs, smart things is sucks. from voice/gesture recognition to application.
I think this may evolve in the firmware. LG is excellent with firmware updates.
2- it seems that black level is better at samsung side. although there is no review on es7500 and i assume it has same panel like es8000 which there is a alot of review out.
it seems??? not sure why you think it seems better.....I would put my set up against a Samsung ES8000 any day......in my environment.
I said seems because of these review. skip to near end of reviews to see numbers.
3- 3d is better on LG camp.
um...to me, this is not a selling point, or a buying point. Figure out which has the best picture for what you will primarily use it for.
4- samsung es8000 has double contrast that LG.(with assumption es7500 does so)
it is simply true. LG use IPS panel in contrast to s-pva panel of samsung. IPS panel has angle view advantage over S-pva but suffers lower contrast.
this is simply not true.
again you can find proof on previous links and plus this:
es8000 3209:1 2950:1
lm7600 1800:1 1413:1
again, the problem is: there isn't comparable score for es7500 and lm8600.
6- es8000 input lag is same as LG lm8600.( I assume es7500 is like es8000)
I have posted many times about input lag, on this set. I think it is either being resolved in the firmware, or it is only an issue with certain games. I am now playing Black Ops2 and experience zero lag
Am I wrong about aforementioned info? is there anything I missed? and about clouding or flashlight problem, I found LG fans seems has more complaints more than samsung.
I don't know how you can say this either. Are you going by the number of posts in this forum? You will have this issue with all large edgelit panels. I don't think it is hardly an issue with a 46" panel. And mine is a 55", almost completely eliminated in my settings.
I read many posts at official forum of LM8600 and es8000&es7500 (AVS). this is how I said. However, You mention good point about Size.
One more things, does LG play various video format. I can't find any info about it.
samsung mention in the user manual that it can play, it also mention about subtitle and srt format...
