3D Technology Checklist
This product is 3D-related. To help you get a great 3D experience, use the checklist below to ensure you have everything you need. 3D viewing requires:
|A Display |
First, you'll need a 3D-ready display--whether it's a 3D HDTV, 3D projector, or 3D computer monitor. These displays have more processing power than standard 2D models for displaying 3D images in rapid succession.
|A Source |
Your display may be ready for 3D playback, but you'll still need a device to read 3D content. This can be a cable box with a subscription to a 3D channel, a 3D Blu-ray Disc player, or a PlayStation 3 system.
|3D Content |
3D content--the actual entertainment, in other words--will be played back using the source mentioned above, whether it's a 3D broadcast from your cable provider, a 3D Blu-ray Disc, or a 3D video game.
|3D Glasses |
For now, the vast majority of 3D HDTVs require glasses for 3D viewing. Many use powered "active shutter" glasses, others polarized "passive" glasses. You'll need one pair per viewer, and they'll have to be compatible with your display, whether they're the same brand, or a pair of "universal" glasses designed to work across brands.
|HDMI Cable |
To connect your source (such as a 3D Blu-ray Disc player) to your display, you'll need a high-speed HDMI cable. Cables with this designation feature bandwidth speeds up to 10.2 Gbps (gigabits per second), for carrying the 3D signal without any loss of quality.
If you want to get more information about 3D, shop our 3D products, watch videos, or interact with other customers, we invite you to visit 3D 101, our customer center about everything 3D.
3D in Full HD 1080p
Enjoy an immersive, realistic movie and gaming experience in Full HD 1080p using Sony's 3D active glasses and connecting a compatible 3D Blu-ray Disc Player or PlayStation 3 gaming console.
Sony's 3D glasses are adjustable and comfortable, designed with side panels to block out excess light that can create an annoying glare on other glasses. Better yet, they fit over prescription eyewear, and feature batteries that last up to 100 hours.
When viewed through the active shutter glasses, the on-screen image is precisely synchronized and delivered with the image intact, for an optimum 3D viewing experience. And since each frame you see is shown at Full HD resolution, the 3D action comes alive with razor-sharp detail.
In fact, from the moment you turn on the NX720, you'll notice a sharp, vibrant picture, whether you're enjoying 2D or 3D content. Sony's video processing technologies work together to deliver breathtaking picture quality with reduced visual noise, enhanced color and overall image detail, even on 1080p sources such as PlayStation 3 systems and Blu-ray Disc players.

Smart Design, Smart Features
Corning Gorilla Glass
Enjoy an incredibly durable, remarkably lightweight, frameless design with Corning's exclusive Gorilla Glass. Combined with the Opti-Contrast panel, this HDTV boosts contrast, increases brightness, and minimizes unwanted light reflections.
Intelligent Presence Sensor
Enjoy an incredibly customized picture and sound experience every time. Sony's Intelligent Presence Sensor uses built-in Face Detection technology to turn itself off if no one is watching, warns children when they're too close to the screen and adjusts picture and sound based on where people are sitting in the room.
Energy Saving Switch
Even when turned off, most electronics are still using energy if they are plugged in. With Sony's Energy Saving Switch you can easily eliminate this standby power without the fuss of plugging and unplugging the cord. When the switch is turned in the "OFF" position it reduces the television's standby power to nearly nothing.
USB Photos, Videos & Music
Share your photos on the big screen or listen to your favorite music. Simply connect your digital camera, USB-enabled MP3 player, or USB storage device directly to your HDTV's USB input.

Top Customer Reviews
The picture processing is amazing with brighter picture and excellent black levels. The black color is real black not blue black like before.
I have connected regular DVD player and Blu-ray player to this TV. I have compared 1080/24P (Blu-ray) picture vs 1080/60P (DVD). I have done this test with the movies Inception, The Dark Night and Shrek. The DVD picture quality almost matched with Blu-ray picture quality. Black levels, picture consistency and amazing crispness have been achieved through the OptiContrast panel and X-Reality Engine. Blu-ray movies are awesome with this TV but DVD movies are no less. You can rent DVDs from Redbox and enjoy the Blu-ray picture quality.
When I connected the TV to regular DVD player in Standard Definition mode, the TV has automatically upgraded the picture. I had some doubts over the SD contents before buying, but this TV came up with better SD content and picture processing than previous TVs from Sony. When I have compared this with my other Samsung LED 46D8000 TV, I could see that Sony has bettered the SD picture processing. The TV upgrades the SD content to HD content level. This is the best part of this TV.
Sony and Samsung have kept certain benchmarks (standards) for the TVs in their own path. Sony until 2010 did not venture into reflective screens where Samsung was outclassing the Sony's matte finish.Read more ›
Right out of the box, the picture is quite stunning. The colors are accurate and the contrast ratio is very good. As usual though with any "default" setting, the sharpness is up too high revealing digital artifacts with too much edge enhancement. A quick calibration with any calibration DVD or Blu-Ray takes care of these problems. I will say that I did not need to adjust the color and tint settings. They were spot on.
When you first turn on the TV, you are presented with a series of screens to setup language, screen settings, network and other various options. It goes pretty quick. Nothing too difficult. If you use MAC security on your router, you will need to skip the network setup part and do it later since you will need to retrieve the MAC code from the network setup menus. Also, the internal WiFi adapter is 2.4 GHz only. It does not run at 5 GHz. You will need a separate adapter to do 5 GHz.
Once I had everything setup, I did various tests from different sources. Satellite TV, Blu-Ray and online streaming from Netflix and YouTube. All looked excellent. As much as I'm not a big fan of "Motionflow" technology, this TV does it quite well so I might leave it turned on. Fast actions scenes with Motionflow look quite amazing.
The anti-glare glass screen is the biggest surprise. Reflections are very subdued so if you have lots of light in the room, you won't have any problems seeing the picture.
3D from true 3D sources work as expected. Things pop right out of the screen. The simulated 3D works just OK. Depth is not all that great. It's more of a novelty than anything else.Read more ›
The setup was reasonably easy and quick. The TV found my network and connected with no problems. The Internet setup of this TV is somewhat different than that of the Sony Blu-ray I purchased to accompany the TV. The Blu-ray allows me to easily access Amazon's free-to-Prime customers downloads of movies and TV shows. I haven't been able to figure out how to make the TV access as easy. Of course, I don't "need" the TV access because I have access via the Blu-ray player, but in some sense it would still be nice if I could use the TV itself for access. I don't (yet) subscribe to Netflex or similar services, so unfortunately I have no comment on their ease of use. Edited to add: After the TV updated itself (very easy!) it no longer was able to connect to the Internet. My computer-expert son had to manually connect it. If I was able to subtract a halof-star so that the rating was 4.5 stars, I would do so.
The instruction book is on the skimpy side. Thankfully there is an "i-manual" on the TV itself, which is handy. Still, I guess I'd have liked more detail in the print manual, especially about issues such as setting up Internet access. On the plus side, the TV just finished up-dating its software with no glitches, so I know that my Internet access is at least semi OK.
The picture on the TV seems significantly brighter than that on the old TVs. I like this feature.Read more ›
