Our Score:


Sony has developed a habit in recent years of launching interim TVs; sort of 'v1.5' models tucked in between the main courses of its headline annual TV range launches.

The 40in KDL-40NX713 is one of these v1.5 TVs, turning up to inject some new life into Sony’s current LCD range while we tick off the months before the launch of the brand’s true next generation models.

With this in mind, we didn’t really expect many surprises from the 46NX713. But maybe because of our relatively low expectations, the set has actually ended up impressing us - and it’s even introduced a surprise or two along the way.

The 40NX713’s design gets things off to a great start. For it’s immediately apparent that the 40NX713 is twice as slim (at just 32mm) round the back as the original 40NX703. Couple this new-found slimness with a single-layer, glass-fronted black-edged fascia, and you’ve got a seriously stylish TV that delivers much more satisfyingly on the 'Monolithic' name Sony has attached to its latest TV fashion. You can also slot the set into Sony’s optional, ultra-stylish SU-B400S silver bar, within which you can tilt the TV back up to six degrees if you wish.

We haven’t tested one of these stands yet, though, and we’ve heard unconfirmed reports that the bar-style stands can muffle the sound produced by the speakers in the TV’s bottom edge. If anyone has experienced this - or, indeed, has had the opposite experience - please add your thoughts to the comments section.

With the 40NX713 set up on its standard, chunkier but still not unattractive 'standard' desktop mount, it also strikes us that the 40NX713’s bezel is much narrower than that of the 46NX703. Part of us actually liked the almost scary, indomitable presence of the larger Monolithic models, but with our sensible head on, the new, trimmer fascia is both sleeker and more practical, given the limited space of your typical UK living room.

Obviously, given the 40NX713’s slimness, wall-hanging is an attractive option. With this in mind, it’s nice to find that Sony has arranged the set’s connections so that you can access them from the TV’s sides, rather than from the rear.

The already very positive feelings raised by the 40NX713’s improved design increase as we tally up its connections. Its four HDMIs should keep pace with the demands of all but the most excessively ambitious home cinema fans, while multimedia duties are catered for by a USB port, a D-Sub PC port and a LAN socket.

The USB can play back video, photo or music files, as can the LAN socket from DLNA-enabled devices. Even better, the set carries built-in Wi-Fi, rather than forcing you to cough up for an optional external USB dongle. Actually, given the presence of just one USB port, it’s probably just as well that the Wi-Fi is built in.

The LAN port and Wi-Fi connections also provide support for future interactive services associated with an in-built Freeview HD tuner, and enable you to access Sony’s Bravia Internet Video (BIV) platform.

We’ll come back to BIV in a moment, but first there’s one more rather important connection to note: a 3D Sync terminal. This is there because the 40NX713 offers active shutter 3D playback as an optional upgrade.

I have the predecessor for this TV, the NX803 (which is a great TV), which I use with the silver 'bar' stand.

Whilst the stand makes the TV look great - I definitely noticed a deterioration of sound quality. This took the sound quality from adequate (7/10) to poor (5/10). This can be addressed with the use of a separate speaker system, of course.

I find it interesting that this model has no backlighting issues, What Hifi have a review of the 40EX713 which is also an Edge-LED model gets a lot of negative comments because of uneven backlighting/backlight bleed. Sounds like there's a bit of a lottery with Sony's quality depending on which specific model you go for.

I think it does incline me to caution before going near their TV's!

Although it looks like their 2011 range is going to feature some direct LED local dimming models which sounds worth holding off for.

@John - where did you find this at £699? PRC direct have it for £789 and only as an In Store purchase.

I've just seen it in store at John Lewis and it does look good....tough call between this and the much pricier Philips 9705

TR - still can't find it for £699 :-)

@gdawg304 - I have done some digging on your behalf. This model was definitely for sale as low as £699 over the Christmas period, and as is the case with all our reviews, was for sale at that price on the day of publication.

Of course, prices do fluctuate and are subject to the usual forces of supply and demand. I'm sure it will come back down in price over time from the current levels.

@ Geoff - this may be the case, however on date of review publication the retailer which you listed as £699 online (PRC) was selling it for £789 and *only* as an in store purchase.

Not that I'm implying the review is attempting to mislead as I know that's not the case at all!! Just annoying as for £699 I'd have probably bought one, but for £1k+, no way.

Looking around, a lot of places seem to be increasing the price of this TV, Marks & Spencers for example bumped it up from £999 to £1199, right before Sony refresh their range for 2011 - doesn't seem like the time to be raising prices on "old" tech.

On another note I'm seeing the Panasonic P42V20 rapidly dropping in price and available for as low as £829 which seems like a damn good price for that TV

I have the sound bar and contrary to what is suggested in the review, the sound is diverted from the TV speakers to the speakers in the sound bar, therefore there is no deterioration of the TV speaker sound as these are not used when the sound bar is in use. However the sound is improved immeasurably with the use of the sound bar, giving a far superior, fuller sound.

Could you please post your final calibration settings alluded to in the review?
Many thanks and keep up the good work
