Very close to OLED, no fear of burn in

Took delivery on 9/22/2019. Set up was straightforward. Image quality is very close to OLED (95%, just straight from the box; I am sure it will be more like 98% once the picture settings are fine tuned by the operator/owner) but without fear of burning in images. IIRC, Apple Inc. will be using the nano technology in their various product displays in addition to the OLED as an alternative.The sound quality from the built in speakers are more than adequate for an open living room that is 18 ft x 16 ft, and is open (i.e., no separating walls) to the breakfast nook and kitchen. It is so good that I moved current sound bar and subwoofer to the master bedroom for use with a 60-in LED TV that is 10 years old and going strong.The smart remote uses motion sensors and Bluetooth technology and is almost intuitive. There is much less hassle (by not using the round multidirectional cursor control panel). This is my first time using the WebOS on the remote and it only took less than an hour to get used to its features. Plus there are video tutorials at the LG website. I still have to try the Alexa and Google Assistant features.I've connected Apple TV 4K using 8K compliant HDMI 2.1 cable rated at 42GBps. The screen saver photos are amazing!Overall, I am quite satisfied after more than 2 weeks of daily use.

I've had the tv for a couple of weeks now. I'm impressed with the picture on this 75 set. I replaced a 73 set, and the difference is pretty amazing. The only drawback is the menu. Trying to find settings like brightness and contrast, took considerable time. This set is well worth the money.

Absolutely love it!!

This is a beautiful TV with an awesome pictue and sound. Love the magic remote and how it interacts with the TV. So glad I bought this as it works with the main apps that I watch like Netflix, Hulu, Amazon Prime, etc.
