Sony KDL-40NX713 review


Sony's Network (NX) range is not only drop-dead gorgeous, but the models are also decked out with all the latest features, including 3D, network streaming, online content and LED backlighting. But you may wonder why there are multiple versions of the...

Outstanding HD picture with exceptional motion picture clarity; Freeview HD tuner, integrated Wi-Fi

External 3D sync transmitter required; limited media file support

Jaw-dropping image clarity is the calling card for this spectacular Sony TV

Sony Bravia KDL-40NX713 - Pocket-lint


3D ready rather than 3D-equipped, this step-up set from Sony is nicely positioned for anyone after a top draw, future-proof flatscreen - and it comes complete

Freeview HD pictures, Blu-ray, BBC iPlayer, user interface

Blotchy LED backlighting, 3D kit not included

Yet another strong screen from Sony, with decent pictures across all sources and its best-in-the-business Bravia Internet Video service. A superb all-rounder for 2D, there is an option for a 3D add-on but that will set you back a few hundred quid at...

Sony's 40' network TV range aims to be all things to all viewers

Wonderful HD clarity ; Beautiful design ; Freeview HD tuner ; Wide viewing angle

Uneven LED backlight ; Poor network media support ; Separate 3D sync transmitter ; 3D crosstalk ; Redundant Yahoo Widgets

Step up from Sony's mainstream EX TV range and you'll find the first of its 3D designer models. The NX Network sets combine advanced multimedia capability with premium picture performance and Sony's trademark Monolithic Design.

Sony Bravia KDL-40NX713 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

It’s difficult not to be impressed with the KDL40NX713's design and comprehensive online features, but it’s not perfect. 3D video quality was reasonable but we were disappointed with file format support, an important feature for any TV that includes...

Sony KDL-40NX713 review


Indeed, with a sub-£1000 price tag, and the ability to provide decent three dimensional images alongside top-notch High Definition visuals, the Sony KDL-40NX713 will probably be the first stop for those who want to try the technology, but aren't ready...

The Sony KDL-40NX713 isn’t the most advanced 3D television you’ll see. Indeed, if 3D is the top priority for you, you’d be advised to look elsewhere. But you should still be able to get an enjoyable experience from watching even 3D on this screen, and...

Sony Bravia KDL-40NX713


This 40in LED backlit LCD television is a fine option as a 2D set and not that bad as 3D one.

Considered first and foremost as a 2D TV - which is, after all, how it sells in its 'native' state - the 40NX713 is a really fine option for a relatively discerning viewer. The price of under £700 we've found online makes it great value too.

looks good

internet TV mising ITV and generally unreliable. Updates should not be necessary to make it work and if really necessary, should be automatic without losing settings

Not to say I’m a TV geek or anything, but I was in the TV servicing trade since they had valves in them and the PC trade since the IBM,PC so maybe I know something appertaining to this TV technology ; To be honest I was blown away by the picture...

Ok its Network/Internet connection functionality. The TV has wireless and a Cat5 wired connection. The wireless connection very intuitive and self searches. I used the wired connectivity as it was more convent for me. Yes it connected to the internet...
