Rated 5 out of 5 by from MORE FEATURES THAN i KNOW WHAT TO DO WITH! I bought this TV during the end of year changeover and was worried that I might be giving up on some new features. I needn't have worried, this set is VERY full featured. the price was excellent and the picture quality is the best I have owned. I like the LG products and this LED LCD TV is excellent in picture quality, exceeded only by the amazing OLED units. But they are far more expensive. The 4K picture quality when playing a good Blu-Ray disk is so great I need to wear my outdoor glasses to appreciate it. An excellent value for your money with a first rate picture.

Rated 3 out of 5 by from Great picture and sound. Bad software. So far, this "Smart" TV has been great for being a TV. Unfortunately, it's menus are insanely difficult to navigate and it's constantly prompting updates, even after I update. Highly annoying, I don't even use the Smart aspect anymore and stick with my Roku. Good video and audio quality though, so I'm keeping it. However I do find it annoying that when I'm watching something where the screen turns black, the TV deadens the pixels. A bit distracting.

I want to connect my tv to a sound bar that only has an audio video cable inlet on the sound bar. Do I need a special cable?

Asked by: Michael1984
The LG 4K UHD Smart LED TV - 55" Class (54.6" Diag), Model # 55UH6090 only has an Optical Digital Audio Output on it for connecting to Sound Bars that also have an Optical Digital Audio Input. If your Sound Bar does not have an Optical input on it, you will need to purchase a Digital/Analog Converter and the necessary cables to connect from the TV to the converter (i.e. an optical cable) and then at the other end of the converter, you will need the RCA analog stereo cables (i.e. Red/White color coded plugs)...^IFV
