Overview

The LG 50NANO75UPA is a 50-inch 4K smart TV from LG's NanoCell 75 series, positioned as a step up from conventional LED panels thanks to its nano-particle color filtering technology. NanoCell works by absorbing wavelengths of light that produce dull, inaccurate colors, resulting in a purer, more vibrant picture with better color consistency across wide viewing angles. This makes the 50NANO75UPA a solid choice for rooms where not everyone sits directly in front of the screen. The 3840x2160 Ultra HD resolution provides sharp detail, while the 120Hz refresh rate contributes to smoother motion rendering during fast-paced content like sports and action sequences.

On the smart TV side, the 50NANO75UPA runs LG's webOS platform with built-in access to all major streaming services, removing the need for an external streaming stick or box. LG's ThinQ AI system adds voice control capabilities through the included Magic Remote as well as through built-in Alexa and Google Assistant compatibility. Active HDR processing with HDR10 and HLG support enhances compatible content with improved brightness and contrast detail. Wireless connectivity includes both Wi-Fi and Bluetooth 5.0, allowing you to pair wireless headphones or a Bluetooth soundbar directly to the TV. While it doesn't reach the contrast depths of OLED or the local dimming precision of higher-end models, the 50NANO75UPA delivers a well-rounded 4K experience with a feature set that punches above its price class.
