Got this on Black Friday at MicroCenter for $630 before taxes.
Read the entire thread and your guy's settings seem really.. Bright... I'm at work, but my panel/brightness/contracts is all in the 60-67 range IIRC. Are you sure you guys don't have white shades on your blacks?
Also, this is a really great TV. My first 1080p plasma I've seen in person outside of stores. The others have been 720p. The 1080p is well worth it for hooking my PC up to and my 720p videos are much more noticeable in quality vs my 1080p videos now. Could never really tell that much on LCD/LEDs.
The person who said reviewers thought the black/white levels weren't that great, I might have to agree. Althought, I think they were exaggerating or coming from the point of comparing this to super high end TVs. I had to sacrifice a bit of brightness to get rid of white tint on my blacks.
I put my trumotion or whatever at 2/10 as well.
I'll try and remember to post my entire calibration when I get home. It looks very good though! Super well priced for under $650. You can't even get all these features on any HDTV regardless of type. Nothing but compliments so far from other people.
My only issues is I wish the black/white levels could be brighter without the depth being effected or tinted and I've seen some temporary burn in happen already, but that is to be expected. Burn in will happen with any monitors/TVs now a days regardless of type. Even my 27in 1440p korean monitor had some burn in happen for a moment.
Kind of wish it was 3D, but at this price I don't care that much. Maybe my 4K TV in the future will be 3D.
This TV also has "120Hz" mode through trumotion or whatever LG calls it. Very notifiable. It on 10/10 and game mode on, I don't notice any lag in video games or sports.
Very much enjoying the TV and the heat it puts off (helps heat me bed room :D). The thing was a bitch to setup though by myself. I couldn't wait for someone else to be around to do it (both before I moved and a week after getting the TV and moving to a new house). The shear dimensions of the TV was the biggest issue and getting a grip without harming the TV.
Haven't tried plex yet, but PS3 Media Server (program) works very well with it. Works MUCH better than my stupid 360. I also love how you can have it play videos one after the other. Makes watching series much better.
