| Bottom line | Albeit expensive and plagued by 3D image issues, the beautifully styled Sony KDL-NX720 has better picture quality than most other edge-lit LED-based LCD TVs. | The Sony HX850 is a smart-looking Smart TV with sparkling picture quality, making it a front-runner for plasma-phobic videophiles. | The midlevel price and outstanding quality of the Panasonic TC-PST60 series make it our strongest TV recommendation ever. | One of the best-performing LED-based LCDs we've ever tested, the expensive local-dimming Sony XBR-HX929 competes well with the top plasmas. | The overpriced Sharp Elite LED-based LCD produces the second-best overall picture quality of any TV we've reviewed since 2008. |
