PROMOTED: Bring 4K HDR into your home with the Sony XD93

Uncompromising HDR performance from an ultra-slim 4K TV

by Promoted Content Poster Jun 1, 2016 - Updated: Sep 27, 2016 at 11:08 AM


  • Everyone is talking about HDR this year but what exactly is it?
    HDR stands for High Dynamic Range and basically it’s a way of taking the increased resolution of 4K and making it look even better. It does this by expanding the dynamic range, (that’s the difference between the darkest and brightest parts of the picture), to give images more impact and widening the colour palette so that colours are more realistic. Why do you need HDR? Well, when you combine the increased resolution of 4K with the higher dynamic range and wider colour palette, the result is a picture that is much closer to real life. The increased resolution means that you can see every tiny detail in the image, whilst the wider colour palette results in colours that reflect the millions of shades you find in nature.

    However it's the higher dynamic range that really makes the difference, with the deepest blacks and the brightest highlights combining to create images that will simply amaze you. If you imagine a campfire scene at night, thanks to HDR the night sky will be pitch black but the light from the campfire will be incredibly bright – just like in real life. What's more you won't lose any of the detail in the brightest and darkest parts of the image, so you'll be able to see the individual flames in the fire and the stars overhead. This huge dynamic range between the darkest and brightest parts of the picture wasn't possible before, making HDR the biggest thing to happen to TV in decades and Sony is uniquely positioned to deliver the best possible experience.

    Why Sony? Well for a start they don't just make the 4K HDR TVs and projectors that consumers use in their homes, they also make the professional cameras that are used to film the movies and TV shows that we all enjoy watching. They make the professional monitors that are used in the post-production facilities to complete those films and TV shows, as well as the professional projectors that are used in commercial cinemas to screen all the latest blockbusters. Sony even have their own film studio - Sony Pictures - which means they don't just make the equipment used in film/TV production and distribution but they also create the content that is then shown on the latest 4K HDR TVs and projectors.

    Sony is the only consumer electronics company that can deliver a complete 'scene to screen' solution when it comes to 4K and no other company offers as broad a range of products bearing the HDR logo. These include TVs, projectors and soundbars, all of which support 4K HDR; along with Ultra HD Blu-rays from Sony Pictures that make full use of both HDR, wider colour palettes and immersive audio. Whilst a large number of Sony’s BRAVIA TVs will support 4K HDR this year, the company’s flagship series for 2016 is the XD93. This BRAVIA 4K HDR TV comes in two screen sizes of 55 and 65 inches, and you can read the detailed independent AVForums reviews of the KD-55XD9305 here and the KD-65XD9305 here.
    What makes the XD93 so special? Well it not only delivers the best possible 4K HDR experience but does so using a panel that is incredibly thin. How thin? Try 12mm at the top and only 36mm further down, where all the connections, electronics and speakers are housed. How can an ultra-slim edge-lit TV produce a 4K HDR experience that is comparable to a TV that uses a full array backlight? It certainly isn’t easy, but what makes the XD93 capable of such exceptional performance is Sony’s ground-breaking Slim Backlight Drive.

    This revolutionary new technology uses LEDs down each side of the panel, combined with two layers of light guide plates to allow precise local dimming control. The two light guide plates break the screen up into a series of grids that allows for greater precision when dimming different areas behind the image. It’s this design feature that gives the XD93 greater precision, less haloing, superior blacks and better backlight uniformity when compared to a regular edge-lit LED TV.
    This means that when combined with Sony’s X-tended Dynamic Range PRO backlighting algorithm, the XD93 can deliver a level of quality similar to a full-array LED local dimming backlight, but from an incredibly slim form factor. X-tended Dynamic Range PRO adds to this performance through precise backlight control that makes darker areas darker and brighter scenes brighter, resulting in an improved dynamic range.

    The XD93 series uses a 3,840 x 2,160 pixel 10-bit VA (Vertical Alignment) panel that allows for full 4K resolution, greater colour precision and superior black levels. The XD93 series also includes the 4K Processor X1 with a Dynamic Contrast Enhancer which is designed to improve the dynamic range even further by optimising the brightness on a frame-by-frame basis, depending on what is happening on the screen. This single chip solution also intelligently analyses and enhances non-4K sources such as DVD, Blu-ray and TV broadcasts to near 4K resolution.

    The XD93 also has the latest version of 4K X-Reality PRO. This powerful 4K picture processing technology analyses the individual parts of each scene and matches them with a special image database that independently addresses texture, contrast, colour and edges. The result of all this image processing is that even non-4K sources can look almost as good on the XD93. So even though there might not be much 4K content at the moment, you can still enjoy all your video sources in the best possible quality.

    The XD93 includes an extensive selection of connections but most importantly it has four HDMI 2.0a inputs, which means they support 4K, wider colour gamuts, HDCP 2.2 copy protection and all the benefits of HDR. The XD93 supports HDR 10, the most popular version of HDR, and you can find HDR content on streaming services like Amazon or Netflix via the TV's built-in apps, as well as on 4K Ultra HD Blu-ray discs.

    So why is HDR such a big deal? Well essentially HDR is a combination of three features that, when combined, result in images that are more realistic than ever before. The first important aspect is that HDR uses 10-bit colour depth, as opposed to the usual 8-bit. This means that HDR combined with the XD93’s 10-bit panel, can deliver far great colour precision and accuracy than ever before.
    The second important aspect to HDR is that content is mastered with a much higher dynamic range than was previously possible. The dynamic range of an image is the difference between the darkest blacks and the brightest whites and the wider that range the more impact the picture has. HDR not only allows for deeper blacks but it also delivers much brighter peak whites that are ten times brighter than was possible previously.

    This doesn’t mean the entire image is brighter, just the highlights, but there is also more detail in these highlights. If you think of sunlight glinting on a chrome bumper, that's an example of a highlight, and HDR’s ability to deliver these brighter highlights makes images appear far more realistic. However HDR can also reveal greater detail in the darker parts of the picture such as shadows and allow both dark and bright elements to appear in the same image whilst retaining detail in both.

    Sony's new panel design and Slim Backlight Drive means that the X93 can deliver the deep blacks and extensive shadow detail that you only get on the very best TVs, whilst producing the bright highlights necessary to create a superior HDR experience. As a result the XD93 is capable of delivering the best possible HDR experience for consumers, with deep blacks and bright highlights, and all from an ultra-thin form factor. Sony's expertise proves that you don't have to compromise on picture quality if you also want the most elegant-looking TV on the market.

    The final aspect related to HDR is a wider colour gamut, which is basically the colour palette from which the TV creates all the colours in the image. The bigger the palette, the greater the number of colours that the TV can create, and the more realistic the image appears. The XD93 uses Sony’s ground-breaking TRILUMINOS display which allows the TV to reproduce a much wider colour gamut. When you combine this wider colour gamut with a higher dynamic range and increased bit depth, the result is an experience that is much closer to real life and better reflects how our eyes actually see the world.

    Whilst HDR might be the hot new topic this year, the XD93 supports plenty of other features such as active shutter 3D, although you will have to buy the glasses separately. The XD93 also includes Motionflow XR which uses frame interpolation, sophisticated processing that analyses the existing frames that make up the picture and inserts extra frames between them, thus creating smoother motion and greater detail for fast-moving sequences. This feature can be especially useful for anyone who watches a lot of fast-moving sports.

    The XD93 doesn’t only include cutting-edge technology on the inside, it also offers an equally striking appearance on the outside. The Slim Backlight Drive means that the XD93 uses an ultra-thin panel but is still capable of a level of performance previously unheard of from a screen this slim. However the design isn’t just thin, it also has a minimalist appearance that incorporates a sophisticated black finish and an incredibly slim bezel around the flush flat screen. The attention to design detail extends to the angles of the stand and the way the panel appears to be composed of two layers divided by a pale gold line down the middle. The XD93’s design is not only very slim but also free of any distracting elements. This is best exemplified by the way that cables can be routed through the stand and hidden by removable covers in order the ensure they are concealed from all angles.

    Although the tapered aluminium stand with its silver finish is very attractive, some owners will prefer to wall mount their XD93 and Sony have included a clever solution. The TV comes with its own dedicated bracket in the box and there are holes at the rear of the panel for attaching the bracket, which you then hang on the wall. The specially engineered rear vents and the dedicated bracket allow you to mount the panel a mere 36.7mm from the wall, giving the TV the appearance of being an integrated part of your living room.

    Although the XD93 is only 36mm deep at the bottom where the built-in speakers are housed, Sony hasn’t compromised in terms of sound quality. The built-in speakers include 4 x 7.5W of amplification but if you want to beef up the bass performance, you can also add an optional wireless subwoofer. The speakers also employ a powerful computer model to analyse and compensate for any inaccuracies in the speaker response. It does this by ‘sampling’ the speaker frequency with higher precision and this information is fed back to cancel out any peaks or dips in the speaker’s natural sound, creating a superior performance.
    You might have noticed that low-resolution Internet video, catch-up TV and other heavily compressed audio files don’t always sound very good. A large amount of information gets lost when digital audio is compressed but, with the XD93’s Digital Sound Enhancement Engine (DSEE), lost frequency components (especially high frequencies) are restored for a natural sound with a more spacious feel. In addition ClearAudio+ fine-tunes the TV’s sound for an immersive experience that seems to surround you. That means you can hear music, dialogue and surround effects with greater clarity and separation, regardless of what you're watching.

    Finally the S-Force Front Surround mimics the way the brain correlates sound sources to create proper volume, time lag, and sound wave spectrum – using only left and right speaker channels. By naturally emulating three-dimensional sound fields, the XD93 can create high-fidelity audio across a wider listening area that sounds more immersive. The overall result is an audio performance that is as striking as the XD93’s looks and as impressive as its picture.
