Right, back to those multimedia features we mentioned earlier. The highlight, for us, is the set’s Bravia Internet Video system. This online service can be accessed via either the TV’s Ethernet port or built-in Wi-Fi system (there’s no need for an optional extra Wi-Fi dongle with these Network series sets), and offers a truly prodigious quantity of video streaming sources from Sony’s ring-fenced section of the Internet.

We haven’t the space to cover everything Bravia Internet Video offers in full here (though we will do so in a dedicated feature we’re doing next week comparing all the main online TV services). But highlights include LoveFilm, YouTube, Demand Five, Eurosport and the recently added BBC iPlayer.

For us the Bravia Internet Video system has the richest amount of content of all the current TV online platforms, and we also admire the stability with which the reams of video sources stream in, even using a bog-standard 2MB download pipe.

The 40NX803 carries, too, a USB port able to play JPEG, MP3, MPEG2 and AVCHD multimedia files, while its network features additionally extend to future interactive services that might come courtesy of its built-in Freeview HD tuner, as well as the ability to stream stuff in from networked DLNA PCs.

The previously discussed 200Hz engine isn’t the only processor aimed at boosting picture quality, meanwhile. Sony’s consistently likable Bravia Engine 3 processing system is on hand too, as well as a decent number of ‘advanced’ fine tuners, like a gamma adjustment, clear white booster, black corrector, and Sony’s Live Colour processing for boosting colour saturations and tones.

There’s a touch of colour management too, in the facility to adjust the gain and bias of the red, green and blue colour elements. But we would ideally have liked Sony to try a little harder in this area. It’s noticeable, in relation to this, that Sony hasn’t pursued third party endorsement from either THX or the Imaging Science Foundation for any of its current TVs.

Not that you have to spend an age fiddling with the 40NX803’s pictures to get some generally very impressive results, mind you.

The 200Hz engine makes an impact right away, helping deliver motion that’s clearly a level or two cleaner and crisper than that of the 46NX703 model we looked at. This helps the picture look generally sharper and more detailed, especially when you’re watching a motion-packed HD source.

We’re always on the look out for unwanted processing side effects with heavy duty motion compensation systems on LCD TVs. But here again, provided you stick with the Standard rather than High setting for the 40NX803’s MotionFlow feature, Sony scores a notable success for the most part. Obvious negative side effects are limited to small objects like cricket or golf balls occasionally disappearing for a fraction of a second as the processing struggles to track such a fast and localised change in image content.

Totally agree with you on Sony's model numbering.

Nice review, but no info on the cost of the optional stand or the performance of its integrated speakers?

Why get THX endorsement and pay that greedy parasite George Lucas a licensing fee. Like you say.....

"and the recently added BBC iPlayer."

When did the iplayer go live on bravia TV's?? thought it was just Sony Blu-ray players that had it so far, great news if it has

Never seen the point in 200Hz processing, except possibly for sport. Blu-ray comes out in 24p, and other sources look exceptionally strange and almost nausea inducing with the processing turned on.

Recommend instead the el-cheapo 40EX403, which still has Bravia 3, 4 HDMIs, a panel that tests almost perfectly by HD Test, and all the Bravia Internet Video features of this one. Except without iPlayer. Does this really have iPlayer, or did you just count your chickens before they were hatched? ;-)

I do like the silver stand, though I think at that price it should be included!

". . .the 40NX803 is easily one of the best edge LED picture performers we’ve seen yet - especially when it comes to producing a convincing black level."

In general terms, are these black levels approaching, or even surpassing, the black levels delivered by Panasonic's plasma TVs? I'm thinking of replacing my Panasonic and I'd like to go LED, but not if it means a significant reduction in contrast.

hmmm looked at three different bravia's last night and NO iplayer so this make me think the reviewer just didn't bother testing these features on the 40NX803 and just maide assumptions based on his previous experiences with Sonys platform on a blu-ray player, so what els dose the review do this on say the 200Hz or the picture quality

you can imagine it "oh yea i remember the last sony i look at had a good picture and this one is the model up so it must be slightly better" 9/10 for you then.

is anybody els not worried by this a reviewer not actually testing what he is reviewing.

dose he realize that people might actually buy a product from his good review. think the lesson here is look elsewhere for your "trusted" reviews.

I love the site but again I would ask it to pull its socks up.

which panasonic plasma do you own?

generally speaking even if an lcd with led backlight in theory surpasses a plasma black levels, that will happen only when viewing head on and within a small range, yet the plasma will offer better overall image quality and deeper black levels from all angles in real world circumstances, and at a better price.

Hi all

Couple of things to add in response to your comments here.

First, regarding the iPlayer, I was told at a recent Sony event that the iPlayer was launching onto Sony's TVs before my review of the 40NX803 went 'live'. But it turns out after chatting to Sony today (August 11) that while the iPlayer is, as HeyZuze points out, already available on Sony's Blu-ray players, it's been delayed on TVs for a couple of months. All Sony will commit to date wise now is 'the 4th quarter'. But it is definitely coming!

As for DrMaustus' comment concerning Panasonic black levels, no, not even this impressive edge LED set can better Panasonic's plasmas - provided, that is, that you go for one of Panasonic's latest NeoPDP models, which start from the G20 series up.

Hi. I have read all the latest reviews of Sony televisions, I find it very difficult choosing wich one to go for. Im not interested in 3D or network connections, just a very good 46 inch TV. I have digital TV signals, if that matters. Good motion is important.

A screen without to many refletions would be great, but I understand that its difficult to find that.

John, thanks for a very useful review. One question - are your comments re. the sound quality on the TV with or without the optional silver stand with its built-in supplementary speakers?
