Rated 5 out of 5 by from Great little TV This LG has been one of the best TV's I have had in a long time. I am very happy with it and have got another LG for a gift. It is a 49" and it is great. I hope it last a long time. [This review was collected as part of a promotion.]

Rated 5 out of 5 by from Great picture & Great price We bought this just over 3 years ago and it is still going strong. Great picture, easy to use and setup, I like the center stand that swivels. Most of the newer ones now come with fixed feet way out at the edges of the TV. Perfect size for our living room. The price was very comparable or better than others in this size and it was a no brainer when you consider the LG quality over some of the other name brands and definitely worth a few extra bucks over the cheaper models. Just ask yourself how many people you know with one of the cheaper ones that have junked it out in a year or so because it quit working!! Don't hesitate to buy if you are considering this TV!!! Go for it......

Rated 3 out of 5 by from NO AUDIO OUT This TV let me down. Picture is decent, audio is decent, however there is absolutely NO way to connect this TV to a surround sound system. What a let down. My 10 year old VIZIO LCD tv that I got for christmas when I was 12 years old has optical out, and this has nothing. Will never buy LG products again.

Rated 5 out of 5 by from Great TV for a budget I bought this because it had a low price and LG is known for making high quality products. Its best feature is the green option which allows the screen to adjust it's brightness based on the lighting if the room it is in.

Rated 5 out of 5 by from you don't need buy a sound bar This tv has great sound of its own, you don't have to buy a sound bar. There was a problem with the picture after having it for eight months & they had someone come out to fix it within two days. I really like this tv. I'm going to buy another LG tv for my cabin.

Rated 4 out of 5 by from Great picture for the price This is my first 1080p flat screen and I couldn't be more impressed with how great of picture I'm receiving for the price I paid. Hooked up with my Blu-ray via HDMI my movies look fantastic. I dont have cable tv so I use just a regular antenna to watch over the air broadcast which now most of the broadcasting is in hd. Football games look great. Even PBS looks fantastic! 2 HDMI hook ups with analog and component are perfect for me. My Xbox360 games look great via HDMI. The sound quality is very nice. I've never had to take it past 50%. Overall this is buy I was waiting for and I am very happy with the picture, menu, style, performance, and quality of this product.

I am going to purchase a larger screen LED SMART TV and use the smaller one in my bedroom.. Yes ,people I love my LG LED TV that much !!!

Rated 3 out of 5 by from ok picture, medioc re sound and options I bought the TV almost a year ago and was very happy with the purchase until one day a neighbor had their music playing very loudly. I turned up the volume to find it out it pretty much tops out at 25 which isn't very loud in my opinion. No Problem I thought. I would just purchase a home theatre system to accommodate for what the TV lacked on its own. I later realized this TV ha no audio out options. I don't understand why they would build any TV without the option to upgrade the sound. Kind of kills it for me.
