You could be forgiven for thinking that LED illumination is all that there is in modern LCD’s but, for now, good old CCFL is alive and kicking albeit routinely in the lower reaches of the manufacturers ranges. And such is the fate of the Sony KDL-32CX523 that sits pretty much last in Sony’s pecking order. It’s not without a smattering of features, however, and it lays claim to a Full HD 1080p panel, Internet TV and a Feeview HD tuner meaning just about all it lacks when compared to the recently reviewed EX723 is 3D capability and Motion Flow processing. With current prices starting from around £300, Sony has a rare entrant in the budget market and if recent experiences are to believed, a worthy one. Of course we’d never judge a display by its heritage and reputation so we’ll be putting the CX523 under the same testing duress as any other; how will it hold up?
The most used ‘Smart TV’ features by consumers are the video on demand services and, in this area, the Sonys really do offer plenty. As well as the ‘omni-present’ BBC iPlayer and YouTube apps, owners can also benefit from the Demand 5, LoveFilm and MUBI services, plus a couple of dozen more. Sadly there’s no support for our current favourite, Netflix, but it’s surely only matter of time before that’s added.
Out of Box PerformanceWe were fairly pleased with the default settings in the Cinema mode and the measurements bore out our feeling that things were already close to accurate. As usual we optimised the basic controls to suit the viewing environment and took the following measurements:
Although the blue channel is tracking higher than we’d like (ideally we want the Red, Green and Blue to be together along the greyscale it’s an error our eyes have difficulty in detecting. When we compared the CX523 to a reference calibrated display, we could see that the Sony was just a little ‘cooler’ but, in all honesty, we could have lived with it, as is. A similar error in either/or red and green would have been far less tolerable. The gamma tracking was close to our 2.2 target, chosen for a modestly lit viewing environment but we’d like to iron out the dip at 90% stimulus, if possible. The calibration controls in the Sony’s aren’t the most generous but we’d still expect worthwhile improvements to be possible.
Much as the greyscale tracking was good to the eye, so appeared the colour reproduction:
Our biggest issues here in attempting to hit the Rec. 709 target points are with the off hue red and green primary’s. Again, we’ll be totally honest, it was difficult to eyeball any colour issues and it needed direct comparison to something that was spot on to see anything was amiss, with real world material. The fact that general luminance of both primary and secondary colours was close to perfect is a big help in ‘fooling’ our eyes here and we’ve no CMS to play with, so it’s a good job too! We should be able to improve the slightly off hue magenta and cyan with the greyscale calibration but we’re unlikely to see any major improvements in any of the primary’s. Still, with overall Delta Errors almost all under the level at which they’re noticeable to the eye, it’s an excellent performance from the little Sony.
Calibrated ResultsSony’s White Balance controls aren’t the greatest; they lack the flexibility of other manufacturers' implementations and are extremely coarse, low down, but we can’t really complain if they’re capable of achieving the desired results. Such was the case here…
Although the sliders don’t allow for absolutely ruler flat tracking, it’s close enough not to matter and Delta E’s are under 3 throughout the greyscale. Our colour temperature is very close to 6504K, where it had been running almost exactly at 7000K prior to calibration and we’re all but bang on the x,y coordinates corresponding to D65 on the CIE diagram. Let’s see how the colours fare on the same chart:
As we’d hoped, the greyscale calibration did have the positive side-effect of aligning the secondary colours, on hue, and we were able to further saturate green and red using the Colour slider, although there wasn’t much improvement in eithers hue results. No matter, really, we’re almost hitting reference readings and for a budget TV, it is an exceptional performance.
Picture ProcessingThere were to be no unwelcome surprises in this section of testing. Both scaling and deinterlacing performance with standard definition signals were very creditable and, with the Film Mode set to Auto, both the most common film cadences were detected in an interlaced signal.
With your player set to 1080i the CX523 will correctly deinterlace and display both the video and film resolution tests, when Auto Display Area is set to off in the Screen section of the Display menu. The Sony also exhibited good scaling and filtering performance as well as good resolution enhancement. Blu-ray 24p content was handled without induced judder, as expected.
Gaming PerformanceThe CX523 performed well enough for the casual gamer but a lag of around 40milliseconds is perhaps beyond the tastes of the competitive player. We were expecting slightly better out of the CX523 here, so it’s probably not the one to go for if video games will be a big part of the intended use.
Energy ConsumptionWith manufacturers put under ever increasing pressure to produce low energy consuming products, this area of testing gives one of the reasons they’re shifting to LED en masse. The CX523 in its calibrated mode took an averaged 55W and, in its out of box mode, 59W.
We wouldn’t want to watch all our high definition on a 32inch TV but we do it for you and the CX523 provided fair compensation for our sacrifices. With its virtual reference calibrated results, our Blu-rays were presented in fine order and the 523 didn’t show any undue problems in keeping up with the relatively low frame rates the medium typically delivers. There’s no Motion Flow frame interpolation sorcery on board the 32CX523 and this is perhaps the one area where it loses out to its 3D sibling. Sony’s ‘Clear’ setting does a very good job with fast moving video content and the 523 does exhibit a fair amount of blur with that type of material. Just how much it will bother you is an individual thing but we did find ourselves wincing during some of the Six Nations games. That said, we’re on the look out for issues, rather than just trying to sit back and enjoy and we guess it will go unnoticed by the majority, especially on such a modestly sized display.
Viewing angles aside, the Sony KDL-32CX523 puts many of the far more heralded LED illuminated TVs we’ve seen to shame. No array banding, no flash-lighting, no haloing. Enough said.
- Screen uniformity far better than almost all LED TVs
- Excellent blacks and contrast performance
- Out of box accuracy looked good
- Lots of features - video on demand services in particular
- Better audio than comparable LED TVs
- Calibrated to virtual reference results
- Contrast washes out off-axis
- Blurs fast moving action
- Input lag is not the best
- XMB is a chore
Sony Bravia CX523 (KDL-32CX523) LCD TV Review
Its looks might not please everyone, it is after all undeniably chunky by today's standards, but the Sony CX523 has a good feeling of solidity about it. The relatively stout chassis houses some above average speakers, for this price bracket, and the remote control is beyond the quality of many other entry level TVs too. We’ve aired our grievances, at length recently, over the inadequacies of the XMB as a valid control system for a TV so we won’t labour the point. But we’re not that keen, if you haven’t already got the idea.
Whilst the 523 might lack a few of the options the menus in the higher end Bravia’s carry, it’s not short of features; the highlight of which, for us, is in the large number of video on demand services available. There’s also USB PVR recording functionality, the option for Skype video chat and DLNA networking too. Unfortunately there’s no Wi-Fi built in but you can’t expect the world on a stick at this price point.
The out of box accuracy of the CX523 was excellent and the calibrated results even better, in fact far beyond what we’d expect at this level. Video processing was Sony’s customary success story with excellent scaling, deinterlacing and cadence detection. We did miss the Motion Flow options for some of the sports action we tested on the 523 but at 32 inches, most won’t pay much attention to the blur.
Based on the all-round picture performance and feature set of the CX523 - which are excellent at this price point - we’ve no hesitation in bestowing a Best Buy Award but you’d best grab one fast if you don’t want to miss out on this particular end of line bargain.
