Overview

The LG 75NANO75UPA is a 75-inch Class 4K UHD smart TV built around LG's NanoCell display technology, which uses nanoparticles approximately one nanometer in size to absorb unwanted color wavelengths and produce purer, more accurate colors. This results in a noticeably more vivid and consistent picture than standard LED TVs, particularly when viewed from wider angles. The 4K UHD resolution ensures sharp detail across the large screen, making it well suited for movie watching, sports, and general entertainment in living rooms or media rooms.

On the smart TV side, the 75NANO75UPA runs LG's webOS platform with access to the LG App Store, LG Channels for free streaming content, a built-in web browser, and a home dashboard for managing connected smart home devices. LG ThinQ AI is built in, and the TV supports multiple voice assistants for hands-free operation. Connectivity includes three HDMI inputs, two USB ports, Ethernet, RF antenna input, digital audio output, and an RS-232C input for professional integration. The 2.0-channel speaker system outputs 20 watts and supports LG Sound Sync for pairing with compatible soundbars. This is a used unit sold without manufacturer coverage, so buyers should factor in the absence of a warranty when evaluating the purchase.
