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 KDL-40NX723


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

Impressive 2D pictures, Elegant design, Excellent online services

Sony KDL-40NX723


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

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

Sony Bravia KDL40NX723 review

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

SONY Bravia KDL-40NX723


I bought this product as an ex-display model which came with the sound bar which is much better quality than the standard speakers ; The monolithic design is what sets this tv out from the rest

Complicated startup

SONY Bravia KDL-40NX723


The HD and 3d is a significant improvement on our old tv ; Good vibrant colours ; Sound quality much better than old tv

Not confident in the use of the broadband link and how to use it or the facilities that are available
