Internet-Ready Television

Internet-Ready Television

Internet-ready TVs use your broadband connection to deliver dynamic content, whether it's streaming video from Netflix, new music from Pandora, or a quick glance at today's weather forecast.

Although there is overlap, each manufacturer offers a unique bundle of free or paid services, including streaming video and music, social networking apps, online photo galleries, news and financial updates, weather info, sports scores, and a variety of other smartphone-like applications.

Manufacturers continue to add new content to their offerings, keeping customers current through firmware updates, and making a bit of research a prudent step in your buying decision.

Learn more about Internet TVs, how they work, what services are offered by different manufacturers, and exactly what you'll need to get started at our Internet TV 101 customer center.




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.

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.

First of all this TV has fantastic features. Until now most of the Sony TVs are matte finish screens which are non-reflective. Although Sony TVs are the best but when compared to Samsung, Sony has been lacking a little crispiness and black levels in the picture. Now Sony with this OptiContrast panel has overcome the shadow of Samsung in picture crispiness and black levels.

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.

Size Name: 60-Inch Verified Purchase
This TV is replacing my 2 1/2 year old Samsung 61" DLP. I wanted to get something thinner with no rear projection system and full HD 3D.

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.

Size Name: 46-Inch Verified Purchase
Well, my son loaned me his 40 inch TV to take the place of my 5 year old 30 inch TV. I loved the bigger TV because it was so much easier on my aging eyes. I loved that bigger TV...for a solid 8 days, until it broke. I couldn't simply go back to my 30 incher, so I finally bit the bullet and purchased this TV. After watching it for a week or so, I am very glad I did so.

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.
