The KDL-55HX823 is the most expensive edge LED LCD TV from Sony... is its performance worth the money? Read our expert review to find out.
Excellent 3D, useful upscaling of web sources and an engaging online dimension. Better pictures can be got for less from a plasma though.
Punchy 2D and impressive Internet video services on the Sony KDL-55HX823 are marred by below-par 3D and backlight inconsistencies.
Elegant design and fantastic motion handling, but 3D images lack punch
This slim 3D LED TV is an awesome all-rounder
It has all the streaming features you could want in the year 2011, but who knows what the future holds?
