Sony KDL-55HX823 3DTV review


Sharpness, blur-free, 3D, online video choices, upscaling, user interface, Freeview HD

High price, lacks MKV playback, black levels not convincing

Sony KDL-55HX823 review


We love the sophisticated styling, punchy 2D pictures and impressive line-up of Internet video services on the Sony KDL-55HX823. It's marred, however, by less than sterling 3D performance and backlight inconsistencies.

Deep black levels ; Impressive motion handling ; Decent Internet features ; Stylish design

Below-par 3D performance ; No 3D glasses included ; Weak bass sound

This model has a number of strengths, including its clean and bright 2D pictures, good range of online video content and sophisticated, classy design.

Sony KDL-55HX823


Elegant design, fantastic motion handling, Freeview HD picture, Smart functionality

3D glasses cost extra, detail in blacks can be bettered, 3D images lack punch

Features and motion-handling to die for. Good, but not necessarily great image quality

Amazing picture quality, even from internet source. 3D pictures are also amazing - even from internet streaming
