I took delivery of an LG 55LW550 yesterday and must say 1st impressions are fan bloody tastic!!!
This TV replaces a Sammy PS50A556 for me and I must say(yeah I know its a 3 y.o set) but it blows it completely out of the water!
The Black levels are excellent.
I have experienced no clouding or banding(as yet....but at this stage if I do, I think it will be due to source)
I have very slight light leakeage in the corners of the screen,Only on a completely black screen though (But I haven't tweaked backlight settings as of yet)
I watched some SKY 3D along with MvA and some converted 3D and hands down easily the best, most comfortable 3D I've used in a Domestic setting.(and excellent in 55'' :P)
The scan lines(From the passive FPR method) become visible from @ 4and a half feet....But its not like alternating black lines....More like the lines on a CRT display.
Motion seems to be handled well, that said I will have a better opinion after the footie today Only Sport I've watched so far is golf In which the ball tracked well with no blurring/streaking.
Any questions lads fire away if I can answer them I will.
PS
The transparent lip on the Bezel is a lovely touch...I backlight(bias/ambience) my TV with an Apollo LED kit and it gives a lovely glowy effect all around the bezel....Looks sweet
