What people are saying

Rated 3 out of 5 by from Ultra HD I bought this in Jan 2018 but in March of 2020 it developed what is called a dirty screen effect which is a uniformity issue with grey areas in bright or white areas

Rated 4 out of 5 by from Great TV for the price I love the overall look of the tv. It has a nice thin border and sleek screen. The picture is great, although it is my first 4k tv, so i dont have much experience to really compare it to anything else. Sound is good, gets plenty loud. My only con would be its been a little difficult to get the picture settings just right for when im playing rdr2 on ps4, its a little too dark and hard to see. It can also get pretty hot after long usage and heats my room..

Can I use a Sonos sound system with this tv?

Asked by: Sabatier
HI Sabatier. Unfortunately, without knowledge of which SONOS sound system you are inquiring about, we cannot specifically say how you would connect it to the LG SUPER UHD 4K HDR Smart LED TV - 55" Class (54.6" Diag), Model # 55SJ8500. However, the Sonos wireless sound system works by connecting one single speaker to your home network, then adding more Sonos units (up to a maximum of 32, dotted around the house) into the mix using a dedicated secure wireless mesh network known as Sonosnet. The SONOS Sound System comprises a number of devices such as Sonos Play:1, SONOS Play:3, Sonos Play:5, Sonos Playbar, Sonos Playbase and the Sonos Sub, all of which are designed to work with a variety of products from various manufacturers. We recommend that you contact SONOS for any inquiries about connecting it to your home network so that it can work in conjunction with the 55SJ8500...^IFV
