From the Manufacturer

Sony make . believe

It enhances the quality of everything you watch for a picture that's four times clearer than regular HD1. You'll experience depth and shades of color never seen on a TV before, and with 65 watts3 of powerful, cinematic sound plus Wi-Fi connectivity5 you have the most complete, highest resolution experience we've ever created.


It's like 4 HDTVs in one

The X900A delivers a picture so clear it's like combining the resolution of 4 HDTVs into one. With over 8 million individual pixels (3,840 x 2,160) compared to about 2 million (1,920 x 1,080) on your current HDTV, your favorite shows have never looked better. Advanced picture processing ensures that every scene is displayed with superb brightness and authentic detail so won't miss a thing.

HD enhanced to 4K
Ultra HD quality

Sony’s unrivaled 4K X-Reality PRO picture processor enhances everything from sports to TV shows to Blu-Ray Disc movies. Based on ten years’ experience upscaling movies to 4K in over 15,000 theaters worldwide, Sony has developed and perfected a processor so advanced, it can upscale HD content to 4K quality. This guarantees that everything you watch today is heightened with the expanded color and clarity that only Sony can deliver2.

See colors never seen on a
TV before4

See a wider range and more brilliant colors than ever with Sony's unique TRILUMINOS display, giving you our most authentic viewing experience ever. Hard-to-reproduce reds, aqua blues and emerald greens are displayed beautifully, so landscapes and seascapes look more vivid, while faces look better with more natural skin tones.


With built-in Wi-Fi5 you can stream beautiful video from your favorite sites like Amazon Instant Video, Netflix, YouTube and HuluPlus. You can connect to even more movies, music and apps by wirelessly mirroring what's on your compatible Android smartphone11. Put simply, if it's on your phone, it's on your TV.

The dynamic LED difference

It's all about perfecting a natural look. Dynamic Edge LED backlighting with local dimming displays your movies and shows with tremendous accuracy and detail, especially in dark scenes where details tend to get lost. Contrast boost in just the right areas creates pitch-black night scenes and bright scenes that pop with vibrant color.

Sound innovation

Powerful sound is directed right at you through the 65 Watt front-facing speaker system3. Innovative Magnetic Fluid Speaker technology reproduces faithful high-fidelity sound from a compact loudspeaker. Combined with S-Force Front Surround 3D with virtual 5.1 sound, it creates an enlarged audio 'sweet spot' that everyone in the room can enjoy.

Recreating natural motion with reduced judder and less blur, Motionflow XR 960 helps you see each end-over-end rotation by taking motion clarity beyond refresh rates, which are only measured in Hz, to quadruple the motion effect so you see everything as if you were there.

Your smartphone, now on TV

Movies, music and apps from your smartphone can now be viewed big on your TV. With three ways to connect Android phones and tablets to the X900A, Sony is helping you add value to the entertainment you already own.

1. Using a Mobile High Definition Link cable, you can connect your smartphone to the TV to literally “mirror” what’s seen on the smartphone screen. Video, photos and apps are re-sized and scaled to fit the larger TV screen. You can then use the TV remote to navigate the phone, while it’s charging from the TV10.

2. Using screen mirroring technology, you can connect phones that are Miracast enabled to the TV11.

3. Using One-touch mirroring with NFC technology, briefly place your compatible Xperia smartphone to the one-touch remote. You’ll instantly be able to view exactly what is on your smartphone’s screen on the TV13.

Frequently Asked Questions

What is the difference between 1080p and 4K?
4K Ultra HD TVs deliver more than 4 times the resolution of 1080P HDTVs. On a 1080p HDTV, there are over 2 million pixels that make up the image while on a 4K Ultra HD TV, there are over 8 million pixels. The resolution of an HDTV is 1,920 X 1,080 (horizontal X vertical) while the resolution of a 4K Ultra HD TV is 3,840 X 2,160 (horizontal X Vertical). Since there are 4 times more pixels, 4K Ultra HD TVs can more easily reproduce the smallest details. Due to this increased resolution, you can now sit closer to a larger TV screen and enjoy a clearer picture.

Will my regular cable programming, Blu-ray Discs, DVDs, and streaming entertainment appear different on my 4K Ultra HD TV?
Yes. The Sony 4K Ultra HD TVs enhance the picture quality of everything you watch with Sony’s exclusive upscaling technology2. The Sony 4K X-Reality PRO Picture engine analyzes and refines images from all sources. Your TV shows, movies, sports, and streaming entertainment will look better2. And with more than 7,000 Blu-ray discs on the market, there is plenty of movie content to enjoy at home, now upscaled to near 4K.

How close to the TV must I sit to appreciate 4K?
The short answer is that between 5 and 6 ft. is the ideal viewing distance for a 55” or 65” Sony 4K Ultra HD TV.

However, on a 55“, you can now sit as close as 3.6 ft and enjoy a visibly smoother and more detailed picture (e.g you won’t see the individual pixels). On a 65“ TV, you can sit as close as 4.2 ft. to appreciate 4K.

Since the pixels on a 4K Ultra HD TV are four times smaller than on an HDTV, it becomes harder to see them. In fact, you can sit closer to a 65” Sony 4K Ultra HDTV than you can to a 35” HDTV. When you sit closer to the screen, you feel like you are immersed in the action. You get the same visual impact as you would sitting in the best seat at a movie theater.

What can I currently watch in true 4K? In near-4K?
For your immediate enjoyment of your Sony 4K Ultra HD TV, Sony's unrivaled 4K X-Reality PRO picture processor ensures that all of your existing TV programs, sports and movies are upscaled to super clear 4K quality2.

Starting in May, 2013, customers can purchase a select number of Sony Pictures Blu-ray titles optimized for 4K Ultra HDTVs. These HD titles were created from the highest quality 4K source materials with expanded color for a more vibrant and dynamic picture. They play on all Blu-ray players and PlayStation 3's. They are the ideal Blu-ray Disc solution for new 4K Ultra HD TV owners and great for Blu-ray collectors as they also display excellent picture quality on standard HDTVs. These titles include: Angels and Demons, The Other Guys, Taxi Driver, The Amazing Spider-Man, Spider-Man, Ghostbusters, Glory, Battle: Los Angeles, Karate Kid (2010) and more are scheduled to release later in 2013.

For the highest resolution experience possible, customers who own a Sony 4K Ultra HD TV can access feature films, TV shows and videos in 4K resolution1 from Sony's 4K Ultra HD Media Player (sold separately) and Video Unlimited 4K service (fees apply). The media player comes loaded with a variety of films and other videos to start enjoying 4K right away.

When will more 4K content be available?
Native 4K content is quickly being adopted by Hollywoods‘ leading filmmakers. In addition, many studios are investing in the 4K restoration of films in their libraries. Films originally shot with 35MM film can be re-mastered in native 4K resolution. In addition, broadcasters and cable companies are investing in 4K technologies to be able to deliver more 4K content expeirences to consumers at home.

What device options do I have to enjoy 4K? Do I need a 4K Blu-ray Disc player and 4K receiver to enjoy my 4K Ultra HD TV?
You can start enjoying your 4K Ultra HD TV with your current Home theatre components. No new devices are needed. You do not need a 4K upscaling Blu-ray player or receiver to use with your Sony 4K Ultra HD TV.

Your current Blu-ray Disc player, cable signal or even your personal photos and videos make for ideal content to view on your Sony 4K Ultra HD TV. You are already creating 4K content when you take pictures on an 8 MP camera, and now you can finally enjoy the full detail of your photos on the big screen.

You can also enjoy feature films in true 4K resolution with the Sony 4K Ultra HD Media Player. The Video Unlimited 4K service will offer ever-expanding options for a library of 4K movies and TV show titles12.
