| Bottom line | The expensive LG 55LW9800's picture quality doesn't live up to the promise of its full-array local dimming LED backlight. | While it's got supermodel looks and pricing to match, the LG LM9600 is unfortunately only an amateur performer. | 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. |
