Best picture settings for LG 55LM4600, Please help !

we just got our yesterday. have not "calibrated" it yet...actually have to do some research into how to do that on our own. but in the meantime, have gone between "vivid" and "intelligent sensor" depending on what is on and have been pretty happy.
only problem we have had is some vibrations when volume is up. i think we are actually supposed to fasten the stand to our entertainment center, but until then have some books supporting beneath the speaker area and there is no more vibration.

I had the same issue with my speakers vibrating on anything past level 16. The back of the tv is metal so that is what is causing the vibrating sound. I just ended up buying a sound bar and the problem was solved it sounds so much better. I read on some other forums that it was a defect that was happening with random sets.. Most places like Bestbuy were just exchanging them and people said they didnt experience it again. Unfortunately for me i bought mine @ video & audio center and their customer service sucks. they said they were going to do me a favor by offering to exchange it once some authorized dealer inspected it, which by the way was after they unloaded and brought it in their store saying i could do the exchange at that moment, they then handed me a card to a place in a whole other city like 30 minutes away where i had to drop it off and invest more time into this problem, then wait three days for a response, then pick it up and bring it back to the original store with some slip saying its defective, then wait another 3 days for them to call LG to verify they would honor the warranty. So i guess being without the tv i just bought for like a week was no big deal to them, and their" favor" was that they normally only exchange within 7 days but to help me out they would make an exception and also not charge me a 20% restock fee. I live in california and told them our return policy is 30 days and he basically called me a liar. I will never buy a tv from them again and will tell all my friends to just stick to BestBuy since i have never had a problem with them. Hope this helps.

Did you get your picture settings fixed. I had better luck getting the settings for my sharp aquos 60 in and that picture looks a lot better. Any help will be greatly appreciated

I haven't heard anything either. Right now I am using intelligent sensor, but at times the is still too dark during shows and movies. I also had to change the settings for games as well because even on the game setting the picture was too dark. I haven't noticed any vibration, but that is because I have a sound system set up, so I don't use the TV's volume at all.

No I have not received a response yet. Please let me know if you hear or figure out some better settings, Thanks.
