Giant footage on a smaller scale


(Pocket-lint) – In spite of the total TV pattern being against ever larger monitors, in terms of OLED generation there is in truth been a rising clamour for one thing smaller. No longer everybody can have compatibility a 55-inch display of their lounge – but that measurement has historically been as small as OLED TVs get. 

Fortuitously there are after all at least 3 48-inch choices in the market for individuals who need the contrast-rich image high quality OLED is famend for however in a extra manageable bundle: the LG OLED48CX, the Philips 48OLED+935, and on evaluation right here, the Sony KD-48A9.

Sony KD-48A9 evaluation: Design

  • 4x HDMI inputs, 3x USB ports
  • LAN & Wi-Fi multimedia choices

From the entrance, the 48-inch Sony A9 is gorgeously minimalistic. The body across the display is each exceptionally slim and sits in the similar aircraft as the picture, so all of it looks as if one immaculate sheet of glass. 

The display sits so low on its heavy accountability, centrally fixed desktop plate stand, too, that from any common viewing distance the display seems to be maintaining itself upright the usage of some kind of magic.


The outer edges of the display are lower than a centimetre deep, too. This outer trimness does distinction starkly, it must be stated, with a central segment of the rear that in truth stands proud greater than the backsides of most present tellies. Until the set goes to be held on a wall, although, the A9’s chunky bits do not detract a lot in any respect from the total supremely sublime glance.

The 48-inch A9’s design does not seem to incorporate any forward-facing audio system. Except for that in truth, it does. For in spite of being Sony’s smallest ever OLED TV, the A9 nonetheless makes use of the logo’s distinctive Acoustic Display generation, the place exactly situated actuators are used to show the display itself right into a speaker. 

The 48-inch A9 is not in need of connections both. 4 HDMIs, 3 USBs, and give a boost to for each Bluetooth and Wi-Fi wi-fi connectivity are all provide and right kind.

Disappointingly, although, not one of the HDMIs can take care of sufficient information to give a boost to 4K streams at 120Hz, or variable refresh charges (VRR). In different phrases, this A9 can not give a boost to the 2 maximum essential new options of the most recent video games consoles and PC graphics playing cards. In spite of Sony in truth making a kind of video games consoles.

Sony KD-48A9 evaluation: Image Options

  • HDR Enhance: HDR10, Dolby Imaginative and prescient, HLG
  • Processing engine: X1 Final

Whilst this A9 may well be smaller than different Sony OLED TVs, it is definitely no much less suave. It will get the similar top class X1 Final processor that every one of its larger OLED siblings additionally get, whole with all of its confirmed advantages.


For starters, it converts sub-4K resources to 4K the usage of an unlimited twin database of image research to offer more practical ends up in real-time. There may be additionally a Tremendous Bitmap device for refining striping out of HDR (top dynamic vary) color blends, and a Triluminos color device that makes use of precision color mapping to ship an enhanced vary of color tones extra appropriately. 

Sony’s Pixel Booster generation is available, in the meantime, to ship enhanced distinction through higher sharing energy round between the person pixels within the A9’s self-emissive OLED display, whilst Sony’s famend MotionFlow processing contributes to stepped forward movement dealing with. There may be even a brand new possibility that inserts partial black frames into the picture to create a extra unique taking a look 24 frames in keeping with 2d (24p) cinematic enjoy, however with out the similar stage of brightness relief that black body insertion typically reasons.

The X1 Final processor additionally powers a normal dynamic vary (SDR) to HDR conversion device that is subtle sufficient to regard quite a lot of items within the symbol otherwise, moderately than simply making use of a conversion set of rules to the picture as an entire. Sony is so assured about the program that it is carried out through default and undefeatably to lots of the A9’s image presets. 

Not like Sony’s A8 OLED TV vary, the A9 is designated as one in all Sony’s Grasp Collection OLED TVs. Which means that every set has been for my part checked over and advantageous tuned in Sony’s factories earlier than being launched on the market. 

As an OLED TV, in fact, the 48-inch A9 provides you with the generation’s key good thing about each and every unmarried pixel in its 4K display generating its personal mild supply and color, in order that the darkest pixel in any symbol can seem proper subsequent to the brightest – with out both compromising the opposite. 


Being self-emissive additionally approach the A9 can also be watched from just about any attitude with none lack of distinction or color – one thing which nearly all of LCD TVs can not compete with. 

Within the pursuits of equity, it must be stressed out that OLED TVs can not reach this type of brightness ranges that LCD units can. The best brightness the 48-inch A9 can reach is 665 nits in its Same old preset, losing to 590 nits in Cinema mode. For comparability: top class LCD TVs can robotically hit greater than 1,000 nits. In truth, Sony itself has controlled nearly 4,000 nits from its extremely pricey ZG9 8K LCD TVs.

The A9 helps 3 top dynamic vary (HDR) codecs: the usual HDR10 device; the HLG layout generally used for reside HDR announces; and the top class Dolby Imaginative and prescient layout, which provides further scene-by-scene image knowledge in order that suitable TVs can ship extra correct photographs. There is no give a boost to for the Dolby Imaginative and prescient-rivalling HDR10+ device – however that is a lot much less frequently discovered within the content material global than Dolby Imaginative and prescient.

Sony KD-48A9 evaluation: Sensible Options

  • Sensible Gadget: Android TV plus YouView

Fortuitously, after a buggy and bulky previous existence, the Android TV interface is after all bettering to the purpose the place you’ll be able to in truth begin to respect the platform’s primary energy: the volume of content material it carries.

Sony’s implementation even comprises Apple TV along the standard Netflix, Google Play, Amazon High, Rakuten, and different suspects, whilst Android TV’s closing blind spots in terms of the streaming products and services of the principle UK broadcasters are coated through the inclusion at the A9 of the very good YouView app. This brings all of the UK streaming products and services in combination into one attractively introduced, simple to browse umbrella app.


Android TV at the A9 proves to be considerably much less buggy than earlier generations, and integrates easily with the TV’s setup menus. There may be not one of the over the top menu sluggishness Android has once in a while led to up to now, both.

There may be nonetheless one thing just a little dated about its complete display presentation, and it nonetheless does not really feel slightly as neatly tailored to TV (versus smartphone or pill) utilization as some rival TV sensible methods. However it is now one thing that is not in truth a chore to make use of, and that’s the reason a undeniable step in the suitable route!

It is price including, too, that Android TV helps Chromecast out of the field, whilst voice popularity/regulate give a boost to is available courtesy of Google Assistant. 

Sony KD-48A9 evaluation: Image High quality

Whilst the 48-inch A9 is not the one 48-inch OLED TV in the marketplace, its image high quality guarantees that it is a distinctive proposition. 

One of the simplest ways to start out growing an influence of simply how beautiful the A9 is to look at is to mention that it is the closest Sony has were given but to matching the famend image high quality of its mythical BVM-X300 skilled OLED mastering track (a display that price tens of hundreds). 


The A9’s dealing with of darkish scenes and black tones is not just nice, as could be anticipated of any OLED TV, it is just about best. It is totally constant, for example, and not using a trace of this type of surprising shifts within the total black tone that you just see with some OLED opponents.

There is no signal of noise, both, be it fizzing or blockading, in spaces of near-black element. But on the identical time the volume of delicate shadow element the A9 brings out of even the darkest portions of the picture is outstanding. 

In different phrases, the display does not simply take the straightforward direction to wash, darkish spaces through sneakily crushing delicate main points out of darkish spaces.

Colors, too, are exceptionally treated. No longer a tone seems misplaced or unnatural, no explicit sun shades finally end up getting an excessive amount of emphasis, attainable color banding is handily suppressed through the Tremendous Bitmapping device, and the sheer vary of tones the display can produce does justice to even probably the most competitive HDR/broad color gamut resources. 

Thank you partially to the finesse of its color control and light-weight regulate, the A9 delivers local 4K photographs with very good sharpness and texture. Such a lot so that you are by no means unsure that you are gazing a 4K display in spite of the A9 being reasonably small through nowadays’s requirements. 


Simply as importantly, although, the sharpness does not really feel compelled. The set simply seems love it’s bringing out each and every subtlety that is found in a 4K symbol, moderately than the usage of processing to artificially sharpen issues up.

The herbal readability continues all the way through motion scenes and sports activities occasions, too, because of Sony’s very good movement processing device. The brand new black body insertion device is beautiful efficient – movement seems much less juddery with out sliding into the ‘cleaning soap opera impact’, and the picture does not lose as a lot brightness as you would be expecting with a BFI-based device. Sony’s common MotionFlow True Cinema possibility, although, is so efficient that almost all customers most probably would possibly not really feel the wish to industry even just a little brightness for the BFI possibility’s moderately extra unique cinematic flicker.

It isn’t simply local 4K photographs that glance detailed and blank at the A9. The upscaling prowess of Sony’s X1 Final processor provides element whilst eliminating supply noise just about flawlessly, reaching remarkably convincing effects with all however probably the most closely compressed resources. Even Sony’s (sensibly restrained) SDR-to-HDR conversion device delivers effects so herbal and plausible that even probably the most die-hard image accuracy obsessives will most probably in finding the device demanding to withstand.

Whilst it is helpful to wreck the A9’s footage down into their other components, the actually key level about them is that they’re nearly freed from distracting shortcomings, mistakes or inconsistencies. Because of this, in fact, that they are phenomenally immersive and pleasant.


If there is a subject with the 48-inch A9’s footage, it is simply that they are now not very vibrant. The measured brightness figures quoted previous are round a 5th less than the numbers measured in the similar cases from many rival OLED units. One thing to imagine for other folks in search of a TV to enter a generally vibrant room, most likely. 

You have to upload, although, that the native distinction have an effect on completed through the Pixel Booster function is excellent sufficient to make sure the A9’s image nonetheless feels startlingly punchy in a dismal room, and definitely does not totally fade into the background when the lighting fixtures are on.

Sony KD-48A9 evaluation: Sound High quality

Issues that the 48-inch A9’s smaller display measurement would possibly result in a decreased efficiency from Sony’s Acoustic Floor generation end up unfounded. The sound nonetheless initiatives ahead into with gratifying directness, and swells out properly to create a legitimate degree that spreads a long way past the outer edges of the display.

There is a beautiful open, rounded really feel to the sound’s tone, too, that even holds up in very loud, dense movie moments. In truth, the sound expands actually properly to include raucous motion scenes; there is not any levelling off too early or scaling down with the heaviest content material such as you get with many TV sound methods.


Additionally spectacular is how detailed the A9 sounds. This comprises some startlingly correct positioning of explicit sounds – voices, gunfire, transferring cars – at the display, and a variety of basic detailing.

The soundstage’s precision slips as soon as it expands a long way past the display, although, proscribing the effectiveness of its Dolby Atmos give a boost to. Bass, too, whilst blank and full of life, does not sound in particular meaty, denying giant soundtrack moments the root of rumbles they wish to ship their complete sense of scale and have an effect on. 


The Sony KD-48A9’s footage are as excellent because it will get. With reference to this type of factor generally most effective observed on pro-grade displays, if truth be told. Particularly if you are ready to darken your room for critical viewing.

It sounds excellent for its measurement too, or even its Android sensible device is after all becoming a somewhat pleasant position to hang around. 

However the 48-inch A9 does not slightly bag a complete five-star rating for 2 primary causes: first, its puzzling loss of give a boost to for the most recent state-of-the-art gaming options (120/4K and VRR). 2d, its asking worth is beautiful steep when an overly an identical 55-inch Sony KD-55A8 is to be had for masses much less.

Choices to imagine



LG’s 48-inch OLED small screen television is brighter and moderately inexpensive than the Sony. It additionally, crucially, helps all of the newest 4K/120Hz and VRR gaming options throughout all 4 of its HDMI inputs. Its image high quality is not slightly as total delicate as that of the 48A9, although, and its extra standard speaker device isn’t slightly as efficient because the Sony’s Acoustic Floor method.

Sony KD-55A8


Except for carrying a much less top class design and now not having every set for my part optimised in Sony’s factories earlier than transport, the A8 OLED vary is an overly shut sibling certainly to the 48A9. And this 55-inch mode can also be yours for much less money than the A9 too – if you are pleased with it being a larger set.
