It has been a mixed bag for Sony this past year with ups and downs in their performance levels, but they did end the 2011 with a big bang by introducing the Bravia kDL-46HX923 together with its 55-inch sibling, the KDL-55HX923. Of course, we were lucky enough to see some top model LCD-based 3D displays from the Japanese manufacturer that was perhaps the one and only to compete with Panasonic’s plasma screens in stealing the show when it came to picture quality and zero crosstalk issues. With the competition increasing by the day, we are only too curious to see how far they go in raising the bar with the 46HX923 and if this does really suffice to keep them ahead in today’s plasma race. Well, it is this 46-inch LCD that steals today’s show and proves to be their flagship model simply because of the fact that it adorns direct LED lighting technology with local dimming as against the conventional CCFL or edge LED lighting. Now with their known history of popularity amongst their existing direct LED TVs, we wouldn’t really be surprised to see that trend continue with the KDL-46HX923 LED TV. Now, the 46HX923’s charm doesn’t really stop with direct LED lighting alone, but also has a boat-load of attractive features that it carries along, which includes an active 3D playback, solid support for media playback, the all new X-reality picture processing suite and finally not to forget the amazing online service access to Bravia Internet Video.
Now a flagship status would mean a premium price tag ain’t it? Well, you guessed it right. For those of you wanting to own the KDL 46HX923 LED TV, it would cost you roughly about £1650. It features a full HD LCD panel, 4 HDMI inputs, Freeview HD tuner, 3D display and LED local dimming (a sure shot attraction that would flock video enthusiasts) helps contrast performance in outstripping the conventional CCFL-backlit or edge LED LCD televisions. As the HX923 looks to be the priciest among its siblings, Sony has smartly included couple of additional accessories to help soften the financial blow as the HX923 ships with 2 pairs of Sony 3D glasses, a microphone/webcam unit (first of its kind move by any manufacturer) that comes in handy with this internet-friendly, Skype-calling compatible TV. For those of you who find it way out of your league, but are a great fan of Sony’s then you might want to check out the HX823 series that is more affordable and has a similar feature list with the exception that it uses edge LED as against the direct LED lighting. Then again, if you are from the “Money’s not an issue” league, then join us in finding out if it is worth burning your hard-earned funds on the KDL 46HX923.

Design and Feel
The Sony KDL-46HX923 46″ LED Television definitely seems easy on the eyes, but we are kind of disappointed as it lacks that stunning effect or the distinctiveness about it when compared to other Sony displays in the past, for instance the iconic V-series or the sophistication associated with the X2000/3000 series back in 2005 making the Black BRAVIA TVs the “happening” thing with silver plastic bezel being considered the “done” thing in the TV market then. Featuring a dark shiny black, thin bezel that surrounds the 46-inch LCD panel, there is a grayish-blue Sony logo that illuminates at the center. The telly has a gorgeous smooth fascia with a seamless one-sheet glass design that has a subtle jet-black bezel. The attractive Sony logo, mentioned above, illuminates (optionally) in the center bottom is what Sony prefers calling Monolithic look, which we are a great fan of.

The tabletop stand has been styled in brushed steel with a fairly simple assembly. With the panel sitting snug on the top of the stand, there are no concerns about the unit’s stability. Getting to the telly’s best selling point (well from an AV enthusiast’s point of view) – direct LED lightning – it is indeed a smart move to have positioned the LED lights on the screen’s rear as against around the edges. This helps the processing power in controlling separately the output of light for each LED cluster thus enhancing the telly’s contrast range way above units that use edge LED lighting. Now isn’t contrast considered the King amongst movie buffs. Also direct LED system means no more boasting of thin chassis, but well it sure does carry the tag of having a monolithic design, as mentioned above, where the black bezel and the screen shares a single plane together with a lavish glint finish. It sure is less glitzy than few of the other designer tellys, but this is only gonna enhance its appeal in a traditional household as against hindering it.
Ports and Connectivity
Do a 360-degree and you get to see more than sufficient bunch of connections at the rear like 4 HDMIs (something that is expected by default from any high-end HDTVs) together with 2 USB ports, a LAN port, a port for D-sub PC VGA input and a built-in Wi-Fi. Again there are Component and SCART interfaces also accommodated through breakout adaptor cables that come in the box. There is also an optical audio output and a socket for LAN for those who do not wish to use the wireless connectivity onboard. Last but not least would be an RF input that comes in handy with feeding the Freeview DVB-T2 HD tuner. We highly appreciate the fact that sony has decided to ditch the additional 3D transmitters with this model that accompanied their first 3D TV and is ready to go 3D right out of the box. Interestingly, there is also a petite camera that is front mounted, which comes in handy with the Distance alert feature (the purpose of it being to detect faces and warn users with kids getting too close to the screen). Also this proves to be fairly handy with the telly’s Skype-calling feature.
Operating the HX923
In terms of menus, Sony KDL-46HX923 3D LED TV is pretty much the same that we witnessed on the lower-end HDTV’s of 2011 that has been passed on to this top-end model with just a single difference – they are fairly rapid to respond. It still feels kind of cluttered. You will have to scroll right or left to choose a main category and up/down to choose the options within. Having selected an option, there is a slight change in the interface wherein the settings appear towards the left of the screen with the same older layout. It is the Display menu that houses most adjustments that are of interest to users. Again, the video controls are housed within the Picture menu with a separate Screen menu taking care of the configuration of Overscan settings together with 4:3 content display.
Getting to the SCENE menu, which is actually the top-level adjustment in the Bravia televisions that is accessed by a dedicated remote control button with various modes on offer here. The idea being users will choose a different mode (obviously with different sound and picture settings) that suits the different genres of film or a programme. Again, the CINEMA mode offers a perfect and intact true-to-spec image right out of the box. Yet another mode of interest would be the GAME mode that ditches some video processing, thus speeding up the responsiveness for PC use/gaming. Beneath this lie the conventional adjustments for Brightness, Contrast, Backlight intensity, Colour, Colour Temperature, Hue (that is active with all signal types) and Sharpness.
Moving on to an interesting adjustment, the Reality Creation that can be best described as an enhancement and sharpening system, which is highly configurable. Then comes the Smooth Gradation, something similar to the Smoothing feature seen on some high-end Blu-ray spinners. It helps with detecting and fixing video image contouring. While other consumer level sources utilize an 8-bit precision, the HX923 operates at a 14-bit level helping such content to be efficiently upsampled. One other vital control would be the Motionflow, the frame interpolation system of Sony’s that helps in reducing LCD motion blur. Finally, getting to the Advanced Settings Menu, the controls are, for the most part, redundant when it comes to user’s quest for accuracy of the picture quality. Then, there are a couple of useful options that would include the LED dynamic control, the Gamma curve adjustment together with the white balance adjustment. This telly is devoid of colour management controls, which doesn’t really prove to be that big an issue provided the colour reproduction is fairly decent and doesn’t require any adjustments.
Features
Multimedia Options galore in the HX923
Recording stuff from the Freeview HD tuner and playing back a collection of media formats is supported via USBs. Again, the 46HX923 can also be paired with a broadband network or a PC to stream multimedia from the latter or access the internet via Sony’s Bravia Internet Video service. The telly’s supports for a wide range of file formats is also fairly robust, nevertheless it is the BIV (Bravia Internet Video Service) that steals the show invariably. Probably one the best online platform until date, to the extent that the variety of video content it delivers aptly suits the kind of internet on TV experience that users would prefer having. Well to name a few – Demand 5 catch up Services, Sony TV archive and Qriocity Movie Database, BBC iPlayer, LoveFilm and an app for Sky News Video Headline. Add to this Facebook, Twitter, Skype, an open web browser together with Qriocity’s music arm and there is an whole load of extra curricular activities that keeps you busy, but there are also few usability issues that tags along this (more on that later).
Getting to the 46HX923’s 3D playback capabilities, the telly features active 3D talents of full HD category with 2 pairs of big and fairly comfy 3D glasses offered free by Sony. Moreover, in contrast to older 3D sets from Sony, the 3D transmitter is in-built in the TV as against being an optional extra. Then there is the video processing that endorses the set to be a flagship model, boasting of both MotionFlow 800Hz and X-Reality Pro, which is a blend of a scanning backlight together with a 200Hz panel and frame interpolation process bringing about a 800Hz effect. The X-Reality’s “Pro” is nothing but an additional processing power that is exclusively designed to enhance the internet video sources.
Just because Sony doesn’t really care for any third-party picture endorsements from authorities like ISF or THX, it doesn’t mean that the HX923 lacks in terms of calibration tools. On the contrary, options galore for those looking at a good tinker, even as few of them look atypical the way they are presented (you guessed it right if you were thinking of the Colour Management System). So getting back, the options vary from allowing you to moderate the strength of the telly’s video processing or deactivating it entirely to a gamma correction, white balance adjustment and colour management system. Obviously, we would urge for caution when it comes to processing elements, particularly the Edge/Detail enhancement and Noise Reduction tools. Also, the MotionFlow tool is worth a shot with fast-moving footage with its Clear and Clear Plus settings. Yet another explicit glitch that can prove troublesome would be the faint clouding that appears around bright objects against dark backgrounds. This is a result of various controllable clusters of LED behind the screen that fails to match (not even close) with the amount of pixels in an image. On the flip side, there is enough flexibility when it comes to picture setting, be it dynamic and punchy or similar to key video standards, whichever way you prefer watching it, there are different setting for different kind of viewing. Finally, one last aspect that we disapprove of would be the telly’s Dynamic control system, wherein despite featuring an “off / low” setting there seems to be a significant drop in contrast together with appearance of bewildering backlight inconsistency when used on anything other than the standard setting. Then again, it is no big deal as you don’t really come across any massive disadvantages in using the Standard setting for the dynamic control.
Sound
With regards to the sound quality of the 46HX923, it puts up a pleasing sound performance with a somewhat open mid-range making it indeed fairly comfy to listen to, at least with some straightforward content, we mean. There is a kind of screech brought about by loud action scenes towards the upper end of the spectrum with a fairly very clear limit to the bass handling capability of the TV. But overall, it definitely sounds way better than the average flat TVs out there.

Picture Performance
Black Level
Thanks to the KDL-46HX923’s locally-dimmed array of LED backlight, it manages to deliver some fabulous contrast performance with just dimming the LED light clusters’ brightness corresponding to the video signal’s brightness. For instance, a sizeable area of entirely black pixels can turn off the lighting entirely behind the appropriate area in the LCD panel, thus producing true blacks. Well, the process wouldn’t seem perfect, but obviously with only limited LED zones to serve the whole 2073600 pixels would only mean that similar to any other LED LCD local-dimming display, the contrast enhancement’s precision is fairly accurate. Per se, there is a slight halo effect seen on white objects with black backdrops that is inevitable in a design as this. So, the minimal on-axis effect looks to be more apparent when viewing the screen from the sides.
Viewing Angle
The off-axis picture quality on the telly beats the other VA-type LCD panels hands down. It is worth mentioning here about an online speculation that questions the panel clocking inside this HDTV, with indication from sources that it is pretty much Sony’s very own. The colour saturation looks to be pretty good and holds up decently well with side viewing and can be compared to any decent IPS panel (but for the grayish-blacks, which IPS are prone to display), even as users are seated on-axis. Well, it is not really perfect, still blacks lack some depth upon being viewed from the side angle with halos, if any, that is a result of local dimming getting more apparent in comparison to complete zero-black areas. Then again, in contrast to older Sony displays featuring sharp UV2A panels, the pixel alignment looks absolutely uniform.
3D Content
3D material in the KDL-46HX923 fare well in many ways – for starters, it is devoid of blatant tracking of Greyscale unevenness giving extra-dimensional images unsolicited colour casts with the colour accuracy being suitably good too. Again, the telly’s performance out-of-the-box is also relatively serviceable. The 3D experience is pretty much similar to 2D with the right eye image carrying a trivial “vertical line” that is visible, nothing troublesome though. In contrast to Panasonic’s Plasma TV’s (2011), the telly manages to resolve all 1080 lines resulting from the 3D source and is devoid of any aliasing or softening and also takes care of the dithering noise in 3D images as it is an LCD-based display. Nevertheless, Sony still has to deal with the crosstalk issues in 3D. It is very unfortunate that while Panasonic and Samsung seemed to have tackled this issue fairly well, Sony has a lot of catching up to do in this regard.
The 3D glasses shipped by Sony have been smartly designed in such a way that it blocks light from the sides of a viewer’s eye. Even as it comes in a thick plastic around the eye area, it still manages to be lightweight and comfy. Well, there is one gripe here though, you need to maintain your eyewear and head completely leveled because of the fact that even a minor tilt of the head brings about a bluish-red tinge to the images.
Running the 3D motion tests in the HX923 brings to your attention the issue with motion stutter. It is very annoying to note that the telly by default introduces an evident motion stutter into the 50Hz 3D content. This gets more apparent with engaging 3D mode on News channels that has a scrolling headline. Luckily, this resolves with disabling the Motionflow feature. Likewise, there is no evident motion judder added by the telly on 24p Blu-ray 3D movies, provided you ensure that the Motionflow is disabled here too.
Standard Definition
While there is absolutely no doubt in the HX923 being a solid performer when it comes to HD material, it should come as no big surprise to note that it continues that same status, if anything even better, in terms of standard def images too. Thanks to the efficient X-Reality Pro engine in adding detail to standard def images along with taking care of the exaggerated noises especially when managing materials from the internet that is often heavily compressed. Again colours don’t really have that naturalness to them as seen on HD, but then it is no big deal and doesn’t really stop you from enjoying standard def images.
High Definition
Similar to the rest of its Bravia siblings, the KDL-46HX923 46-inch Full HD TV fares relatively well upon being fed 24fps Blu-ray film content. The Clear Plus Motionflow setting together with the Auto1 Film Mode helps to reproduce camera pans bringing about near-cinema quality motion that is devoid of any telecine or video judder. But there is some kind of subtle motion processing happening at all times in the HX923, unless you decide to disable the Motionflow entirely. In contrast to Samsung HDTV’s there is no smearing or smudging of grain textures from movies (Blu-ray), meaning all the full-resolution visuals and gritty feel from the films comes unscathed (again provided the Noise Reduction control is disabled).
Colour
When it comes to colour reproduction, the HX923 is absolutely brilliant as it literally pushes colours out of the screen in a rather explosive fashion – thanks to its extreme brightness potential. But for some warm-looking blue tones, the colours of the 46HX923 manage to retain real subtlety, authenticity and credibility, regardless of its aggression.
In terms of HD viewing, the reproduction of colour blends is spotless without any striping or blotching that brings about a HD clarity and purity that gets further enhanced vividly by the TV’s brilliant sharpness and fine detail reproduction. Furthermore, this remarkable clarity is undisturbed even in the face of frenetic action scenes, thanks to both the impressive capabilities of the MotionFlow system together with the minimal response time within the panel, in case you choose to use it.
Again, the telly manages to deliver HD sharpness too and tries not to leave the picture noisy or the edges to seem forced. Aside from the shadowy lines that appear on the screen edges, rarely, the HD images needs to be appreciated for their intense and natural looks making you greatly attached to them. Yet another good news would be that the 46HX923 manages to retain contrast and colour from a remarkably wide viewing angle when compared to other LCDs (although the haloing issue gets more evident with a wider viewing angle) with the standard def images getting nicely upscaled too; at least with regard to the compression noise getting eradicated from the images. On the flip side, the colours lack balance and naturalness with standard def when compared to HD footage, with the suppression of noise resulting in upscaled images lacking sharpness too that can be witnessed on other high-end models. Lastly it is a rip-roaring hit when it comes to 3D content with images getting delivered with impressive depth about them, massive detail to HD content together with exceptional colour richness and brightness by dynamic 3D standards.
Console Gaming
The KDL46HX923BU manages to provide users with a relatively decent gaming experience with an input lag of 31ms in both Graphics and Game mode. Consequently, first-person shooter games like Day of Defeat or Half life might require you to re-adjust to a hefty controls and vaguely tighter-feeling than would have been ideal. Whereas with slower-paced games that doesn’t really require rapid reflexes, like role-playing games, doesn’t really feel out of ordinary even for a slightest bit.
Ease of use
For starters, we are kind of disappointed with the bog-standard remote control that ships with the TV, especially given the fact that this is Sony’s flagship TV. Well, there is actually nothing wrong with the comfy to hold and well laid out remote per se, only that it feels a bit plastic-y and lightweight and doesn’t really match with the lavish build of the TV.
Again, Sony needs to work on the telly’s onscreen menus too particularly on areas like the main menu that is poorly presented, too many small obscure icons to rely on, scrolling through annoyingly long list of submenus and lack of logic in the order of the menu list.
On the flip side, the menus of the Bravia Internet Video have seen a large improvement in comparison to the 2010 models from Sony; nevertheless don’t really measure up to the efficiency, attractiveness or intuitiveness of Smart TVs from rivals like LG or Samsung. At least they are not cluttered like few other rival sets which are literally swarmed up by some redundant apps.
Now having had enough of negatives, let us get to some positives of the 46HX923, for instance, its ease of use. For starters, the sensible picture preset modes is sure to appeal users, especially those who are not a big fan of endless fine-tuning scenarios. Again, it works harder in helping you to economise, via the presence sensor that manages to turn off the screen automatically upon sensing that there is no one around while the TV runs, thus saving power.
Lastly, it also hosts some smart features like the amazing fun TrackID feature that manages to identify a song automatically from a TV show that you might be watching with astonishing accuracy and the best part of it being you get direct access for the same from the remote without having to bother with fiddly menus.

Verdict
For the most part, the Sony KDL-46HX923 looks to be an amazing flagship product and does a real neat job in displaying Sony’s talents. While the design reeks of modest elegance the connectivity looks to be a fab together with an elaborate feature list, including active 3D support, direct LED lightning, advanced video processing system and one of the best online internet video service seen till date. Again, the 2D pictures are nothing short of exceptional with deep blacks, vivid colours, exceptional sharpness, wide range of contrast and neat motion handling. On the flip side, it annoyingly falls short of recommendation owing to its crosstalk issues with 3D content and some weird shadowy lines appearing on the screen edges.
