What reviewers say

The original 2023 65-inch review units impressed with HDR brightness, gaming features and value. Both reviewers found some clouding and softer HD upscaling. They differed on dark-room contrast: What Hi-Fi liked it after careful setup, while AVForums found washed-out shadows and inaccurate brightness. These results do not establish the performance of later hardware revisions.
