The LG QNED80 65" wins overall with superior 120Hz refresh and quantum dot color (per RTINGS and CNET), beating the NANO75's 60Hz panel by a wide margin in motion clarity. The NANO75 counters with a much larger 75-inch display at comparable cost, making it preferable for static viewing. Both use LG's WebOS but the QNED80's panel tech provides measurable advantages in HDR performance.
