What reviewers say
Both reviews of the 65-inch model praised brightness, gaming features and value, but found brightness processing could flatten or wash out the picture and upscaling needed improvement. AVForums also criticised broadcast motion and restricted viewing angles. What Hi-Fi? found sound good by TV standards, though an external system still improved films.
