Rated 5 out of 5 by from Hit the spot This TV rocks! I didn't want a smart tv due to already having an Xbox that would do all those extra features. Plus it doesn't ping/search for wifi so i'm not competing with another device while I am using the TV. The picture quality is awesome, and the thickness is thin. Everything about the TV hits the spot that I was looking for in a TV, especially with gaming and movies. I am very happy about my purchase. Thanks LG!

Rated 5 out of 5 by from Excellent TV This is one of my better purchases. Picture quality is great for HD and is also very good for SD programs. I did not have to do any fine tuning or tweaking - just plugged it in and that was it. Audio is more than adequate and seems to keep the volume level consistent from one station to another. I have nothing bad to say about this TV.

Rated 5 out of 5 by from SMALL SCREEN my screen measurements horizontally is 49 inches so it really isn't a 55 in screen unless you measure it diagonally otherwise the screen is only 49 inches,I wish I had known this before I bought it.
