Rated 5 out of 5 by from Amazing TV for the perfect price I bought this TV 30 days ago and am loving it. It was very easy to setup, Picture quality and sound are awesome. If anyone is looking for a large screen TV for a reasonable price then this is the TV for you.

Rated 5 out of 5 by from Nice product for great price I bought this 10 days o and it was easy to setup the stands and have it assembled and working in less than 30 mins. 1. The wifi and other options are very easy to setup. 2. Netflix streaming works well and menu are easy to navigate around (even my 5 year operates it!). 3. Did a setup blueray player and watched few 1080P content and it looks very good. 4. At 8+ feet distance, 1080P contents looks as good as 4K unless extremely savvy viewer. 5. Set the Energy Saver mode = Off and then brightness is dramatically good for most of bright rooms. 6. LG soundbar SJ4R with optic cable (ARC mode) works well and syncs up nicely! Only con I think is this has some reflections in direct sunlight rooms with lot of windows in daytime and noticeable in dark scenes only, but there is no issues when watching movies at night even in brightly lit rooms. Highly recommended product.. hope it will last 5+ years!

Rated 5 out of 5 by from Beautiful... One week on the wall and I wonder how I lived so long without this TV. You actually feel the movies rather than just watch them. It’s immersive.
