So I read all the reviews, tweeks and concerns but pulled the trigger on this unit at BB two weeks ago. Price was good and thought it would be a decent TV for the man cave. Unfortunately, it's already being replaced with a Tosh 50" similar specs and here's why:
I recently picked up a Tosh 40" for my bedroom and it's one of the best images out of the box I've ever seen. Non HD looks outstanding. The lighting is unbelievable and has self adjusting capability based on ambient light. After picking up this LG, it was a complete disappointment because I've been spoiled by the Tosh. I love Justified and watched a recorded show as my test program. While I fiddled and reset everything multiple times (even used the two recommendations offered in this forum), I just could not get it to look anywhere near the 40" Tosh in my bedroom. After 5 minutes of Justified, the low freq caused the speakers to start the humming/rattling thing like the sound was vibrating the case (it was only turned up to 10!). One thing that drives me crazy is a TV that humzzzzzzzz! And before you all tell me to get sound additions I already have a really decent 5.1 but I don't always use it since everything is not offered in that format. I do like to use on board audio for standard viewing.
So that was the kicker, it's slated to be returned as soon as the Tosh 50" shows up.
