Consumer review (

LG 55SJ800V


Great 4K picture quality. Sounds very good for a TV and has room calibration. Very advanced features and specification. Remote control and interface is very easy to use.

Motion control, and colour balance are a little tricky to setup. Wi-Fi took me about 15 attempts before it connected.
