The features are just as the same as the whole Nano 9 series made by LG the only difference is the screen size. Still produces the best image and sound quality that you can find on this price point and screen size. It is fully compatible and can control other devices that supports ThinQ AI technology. The Nano Cell really produces good color but the full array local dimming, I hope this would be fixable in the future firmware updates.
