What reviewers say
HDTVTest and What Hi-Fi praised the 40-inch model's detailed picture, useful smart features and sound. Both criticised aspects of its 3D motion. HDTVTest found sluggish menus and strong calibrated blacks; What Hi-Fi found the interface responsive but wanted deeper blacks and less red in skin tones.
