Obviously a lot of these in the previous 110 pages odd, but for anyone joining in late and checking last pages that wants an updated review on the "latest build" LM7600's, has anything changed in their manufacturing that gets around some of the issues highlighted earlier? read on....
Just 3 weeks ago I purchased a new 55LM7600 (October 2012 build). Firstly updated firmware to the latest (cannot remember rev no. but whatever the lastest was in early March 2013). Did a quick calibration using the LCD buying guide calibration settings. I found these better than the CNET for my eyes and environment.
First impressions on power up noticed some spotlighting on right edge (2 separate spots around middle height and slight top left (but not as focused as the right edge spots).
Very noticeable on transition and smart TV screens but not so noticeable on regular TV viewing. Seemed to improve over the 2 wks to becoming hardly visible, was pretty happy with this. Then had to remove power to the TV for a day after doing some re-setup of new home theatre system.
When reconnecting power that night, the first power up, I noticed the very vivid spotlighting in same spots as originally, and back to a very vivid state. Was a bit dismayed as thought things had improved, hoped they would die down quickly, but after 1 wk still have it, seems a little better but now bottom right has a soft glow which I'm sure wasn't there before. So watching movie last night I have this right edge and bottom right glow that was really starting to frustrate me. Rrrr these panels teetering on being excellent but seems to be let down by these flaws. Personally I would rather have a wider bezel or pay higher price for more sturdy internals if it meant no spot lighting and prevented this inconsistent "panel lottery" outcome. It really is lower quality than a big name company should be striving for in my mind.
The weird thing is, I can watch in a light-to slightly darkened room a blu ray and be blown away with picture quality, blacks look outstanding in these conditions, 3-D is sensational and 90% of the time I really like the TV. Just bugs me when I see the spotlighting when watching in a darkened room it is distracting.
It does have some banding and again frustratingly this is actually worse when turning the local dimming up to Med which I sometimes feel necessary to lessen the spotlighting. Overall I could put up with its banding, if I could just get rid of the spotlighting. Hoping it will fade away like others have said, and I did see this to an extent already "first time" it was powered up.
Anyone know why LG insist on blasting their high bright, vivid type settings in transitions and menus?, all it does is bring attention to the spotlighting, almost embarrassed to go into some modes with people around, because they may see it for the first time and bring their attention to it. Why couldn't they just have your calibrated settings in every menu/transition? Anyway, has turned into spotlighting rant sorry, but it is a little frustrating for me. The other TV features, smart TV is average, haven't used a lot, but I did have it freeze in youtube apps running on WiFi (good bandwidth). PVR works OK, but annoyingly you can't use any Expert ISF setting saved in calibration, you can choose an option like standard, and adjust a few basic settings. Basically watching anything back on the PVR is a little ugly to watch (when your used to watching your perfect ISF adjusted picture setting).
Gaming on 360- I followed advise on here and labelled as PC and found no lag, works well. PC label gives you some basic calibration setting to get an OK picture.
I have not tested the dual play feature with glasses yet, will report back on this. Anyway overall some disappointments but also had some amazing viewing experiences with 3D blu rays in the right conditions. 10/10 for those, unfortunately the viewing experience changes with the ambient light from amazing to a bit frustrating. But looking at other reviews for alternative sets out their nothings perfect, even more expensive offerings from Samsung and Sony seem plagued with the usual LED issues.
To my eyes, and I did a lot of auditioning in stores for all brands, LG had the cleanest most refined picture, and LM7600 giving best bang for buck.
All above just my opinion of course.
