| Bottom line | Info unavailable | The Sony HX750 series isn't the headliner that you'd expect it to be with a performance that isn't up to the level of the asking price. | Albeit expensive and plagued by issues in 3D, the beautifully styled Sony KDL-NX720 has better picture quality than most other edge-lit LED-based LCD TVs. | Info unavailable | Info unavailable |
