Sony KDL-40NX723 review

 

3D TV more or less justifies its price tag with killer picture performance

Attractive design ; Excellent 2D and 3D pictures ; Extensive connected content ; Intuitive operating system ; Detailed picture tweaks

Extra cost for glasses and Skype camera ; Frustrating internet browser ; MotionFlow picture artefacts ; Relatively expensive

Sony's vast 2011 range of Bravia LCD TVs contains something for everyone, from affordable no-frills sets all the way up to premium screens with more fancy functionality than you'll probably ever use.

Designer looks meet impressive 2D pictures but flawed 3D ones in Sony's latest 40in TV.

Impressive 2D pictures, Elegant design, Excellent online services

It’s expensive, Extremely bad 3D images, Fiddly operating system

Sony KDL-40NX723 review

 

The Sony KDL-40NX723 is let down by dim images and horrible sound

Good-looking ; long spec-list ; motion-handling and detail levels are among the best

Only displays meaningful contrast under duress ; sounds truly horrible

Undermined by one significant flaw, this Sony’s nothing like as good as it could be

Sony Bravia KDL40NX723 review

 

For this review we tested the 40in model in the NX713 range, but it's also available in a 46in (KDL-46NX713) screen size. Those models have identical specifications except for their dimensions and power usage. We're confident that image quality will be...

The stunning design and excellent connectivity makes the KDL40NX713 one of the best high-end TVs we’ve seen, but image quality can’t match cheaper plasma sets
