Rated 4.8 out of 5 by 218 reviewers.
Rated 5 out of 5 by Quality product The picture quality cannot be surpassed as far as I'm concerned, I have friends with higher priced televisions but not higher quality. I picture quality is excellent, it is easy to hook up too. April 11, 2014
Rated 5 out of 5 by Awsome all around! I have had this tv for awhile now, and simply love it, the picture quality is the best I have seen. After buying this I am now sticking with LG for everything! Thanks LG! May 14, 2013
Rated 4 out of 5 by Good features at an unbeatable price This TV was listed on at an incredible price. It has good features, lots of ports for accessories, game consoles, etc. and the picture quality is fantastic. There was a small problem with the unit that caused an electrical failure but LG's warranty covered the fix and their support had a repairman at the house within days to change out parts. As much as I am impressed with the TV I am doubly impressed with the quality and professionalism of LG's support, warranty, and repair service. Even if this particular TV isn't right for you, LG stands behind their products so I would recommend finding something from LG that works for you. November 5, 2012
Rated 5 out of 5 by This product offers an excellant ease of use. Not on;y are the different plug ins a plus the HDMI also offers a fast and effective change from component to component. The best feature I find is not needing the manual and an extra 15 minutes to set everything up. Everything is on the screen and very user friendly. In the near future I will purchase more components and will look at the LG brand first. If all continues with the ease of use it will be the only brand I look at. August 22, 2012
Rated 3 out of 5 Good Product with poor remote ccontroller I bought a new LG 42 inches TV, 42LK450, and pretty happy about its video quality initially. However, the remote broken within 5 months. Worst thing to find out is remote has no warranty; even you could purchase a new remote still no guarantee it will not broken in few months. A TV without an useful remote is not user friendly. I am not sure any customer will buy a TV without remote capability. If that is the case, why the remote has such an incompatible quality vs. TV ? August 6, 2012
Rated 5 out of 5 by GREAT TV I enjoy watching my new LG 32" HDTV. The picture clarity is outstanding. I'm also able to hear the sound as I can raise the volume as high as I need, which I could not do on my previous TV. I was experiencing a bit of pixelation. It was occurring about every 2-3 minutes and lasting approx 3 seconds. An LG tech came out to my home and determined there was nothing wrong with the TV, but the problem was a fluctuating TV signal. I had AT&T U-Verse come out and they replaced my receiver box and VOILA! Problem is resolved. September 11, 2012
Rated 4 out of 5 by Very solid product Purchased to install in a public lobby. Good picture, ease of use. Great features. I would definitely recommend. June 18, 2012
Rated 5 out of 5 by This product has a great picture! This TV is wonderful! The picture is crystal clear and makes it seem as you are sitting right at the baseball field, on the boat with the fishermen, and sitting with the news anchors on the evening newscast. Absolutely the best TV I have ever owned. June 7, 2012
