Product Description

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.

Tap into an almost unlimited library of movies, TV shows, music, and more with built-in Wi-Fi and an enhanced, two-sided remote. The 42-inch class M420SR features Full HD 1080p resolution and a 120Hz refresh rate, edge-lit Razor LED backlighting for a great picture and slim design, SRS audio technology for immersive sound from the built-in speakers, and energy-efficient operation that exceeds ENERGY STAR 4.2 guidelines.

An affordable LED display with Full HD resolution, SRS audio enhancements, and built-in Wi-Fi connectivity.

Connected LED-Backlit Entertainment

LED-Backlit HDTV

The M420SR features edge-lit Razor LED backlighting for brilliant clarity, vivid color and contrast, and an impressively slim form factor of just over an inch.

Enjoy your high-definition sources in Full HD 1080p resolution, with a 100,000:1 Dynamic Contrast Ratio, for a clear, detailed picture with deeper blacks and brighter whites throughout your programming.

120Hz Refresh Rate

The M420SR's 120Hz refresh rate delivers 120 scenes per second, producing an enhanced frame rate for smooth, super-sharp viewing, for fast-action sports and movies that are free of motion blur.

VIZIO Internet Apps

Easily connect to the Internet and stream movies and TV shows, listen to music and get the latest news, sports and weather. The M420SR connects wirelessly over an 802.11n Wi-Fi connection (or via a built-in Ethernet port if you'd prefer) to your home network. Once you're set up, you'll enjoy access to Internet content such as Amazon Instant Video, Netflix, and VUDU for streaming TV shows and movies; Pandora Internet Radio for discovering new music; your favorite social networking apps like Twitter or Facebook; photo-sharing services like Flickr and Picasa; and the latest news from the Associated Press and The New York Times. With a simple Internet connection, you'll get all that and plenty more.

A 120Hz refresh rate delivers sharper clarity of fast-action scenes, for blur-free images.
VIZIO Internet Apps
VIZIO Internet Apps gives you a wealth of connected entertainment options.
Four HDMI Ports

Four HDMI ports accommodate your home theater setup, Blu-ray Player, gaming console, and satellite or cable TV, for a wealth of Full HD entertainment. These also feature the HDMI 1.4 spec Audio Return Channel, meaning you can send audio back to your home theater receiver on the same cable, rather than using the separaate S/PDIF output.

Spectacular Surround Sound

Treat yourself to an audio experience to match that HD video. StudioSound HD provides immersive surround sound over stereo speakers, complete with deep bass and crisp high-frequency details. It also effectively levels abrupt volume fluctuations, to deliver crystal-clear dialogue throughout programming. The end result is a complete and truly engaging theater-like experience over the built-in stereo speakers.

Exceeds ENERGY STAR 4.2 Guidelines

This HDTV takes it easy on the energy consumption, exceeding ENERGY STAR 4.2 Guidelines so your energy bill and the planet are both better off.

In addition, this display's backlight is more than other backlighting methods, since LED edge lights do not utilize mercury, an environmentally harmful substance.

One-Year Warranty

VIZIO offers a one-year limited warranty on parts and labor for this HDTV, for some added peace of mind.

I called Vizio Technical support for my problems.
It would return a message after several minutes that we had no internet connection, but we clearly did - we could watch YouTube, access Yahoo features, etc.

Short version: The WiFi aspect of this television is unworkably bad.

Verified Purchase
Given our positive experiences with Vizio products in the past, we have been stunned by the low quality of this product.

Short version: The WiFi aspect of this television is unworkably bad. You cannot watch streaming content from any provider (Netflix, Aazon Prime, etc.). Purchasing a $70 streaming box and a standard TV is a MUCH more efficient and elegant solution.

The "apps" installed on the TV for common streaming services (Pandora, Netflix, etc.) feature poor user interfaces, achingly slow response times, and low levels of customization. The entire package gives the distinct feel of a product still in prototype phase. It is definitely not ready for prime time.

With strong WiFi signal, you are rewarded with constant interruptions of streaming (5-10 minute pause for re-buffering several times in any given 30 minutes of viewing). Open your laptop in the same room and stream the same content that the TV is streaming and you will see drastically better performance.

After months of frustration, we have installed a stand-along streaming box and treat the TV as a monitor. We are VASTLY more satisfied.

Vizio should be ashamed to have put this product out in the market-place. A perfect example of how to shred hard-won customer loyalty.

I have had my vizio for about a week now and so far love it; the features and quality almost compares to the other higher costing brands; Built in wifi, sound, and picture quality are high. Navigating through the menu might be a bit challenging and its not a samsung but for over 30% cheaper than the competition, its worth every penny.
