We haven't had a chance to fully test this product yet, but we've assembled this helpful overview of relevant information on it.
The Vizio M3D470KD is part of Vizio’s new line of LED-LCD TVs. This series, unlike the other series released this year at CES, doesn’t have any “super-unique” features (the XVT3D0CM with a 21:9 Aspect Ratio and the R3D0VS with a Google TV interface). This TV does come with a 47″ screen, a 240Hz refresh rate, edge-lit Razor LED, a 1920 x 1080 native resolution, passive 3D capability and internet connectivity. The M3D470KD also comes with four HDMI ports and two USB ports. The Vizio M3D470KD will be available in the later half of the year so be on the look out.

Digital Trends’ TV Buying Tips:
What is a LED backlighting?
Traditionally, LCD TVs have used compact fluorescent (CFL) tubes placed behind an LCD panel to provide the backlighting that literally lights up the screen. More modern LED TVs replace these tubes with clusters of light emitting diodes – LEDs.
When LEDs are placed at the edges of the screen, as CFL tubes traditionally were, TVs can be made significantly thinner, and LEDs use less power than fluorescents. The most inexpensive LED-lit HDTVs take this approach.
However, the biggest advantage to using LEDs is realized when they light the screen in a grid from behind. Sophisticated electronics vary the intensity of every LED in accordance with action on the screen, making dark areas of the image darker, and bright areas brighter. This effectively increases the contrast ratio compared to uniform lighting. Although it also increases costs, many people believe this type of LCD is the first to truly rival plasma on black levels.

Do I need a 120Hz set? What about 240Hz?
This popular LCD TV-based technology helps reduce motion blur. Pronounced “120 hertz,” 120Hz technology essentially doubles the speed at which frames are displayed, from 60 frames per second to 120 frames per second, resulting in a clearer moving image, especially in fast-action video sequences.
Since the screen can display more frames than a movie actually has, many TVs will artificially generate in-between frames where they don’t exist to make motion look smoother. Some people find the look more fluid, while some people think it looks artificial and odd. Fortunately, all TVs that offer it also offer an option to turn it off, if you don’t like it. We recommend testing it in person to see the effects for yourself before deciding whether or not you should pay extra.

What inputs should I look for?
A final consideration when buying a new HDTV is what you can connect to it. Make sure there are ample HDMI (High-Definition Multimedia Interface) ports to connect multiple components, such as a cable/satellite receiver, video game consoles, DVD/Blu-ray player, camcorder, and so on. At least three or four such ports is a must. A convenient bonus is when the TV also offers a USB port to connect a Flash thumb-drive or external hard drive full of music, photos and videos, or a SD or Memory Stick card slot that lets you insert a compatible card that contains photos and videos. If you think you’d like to connect your computer to the television for big-screen web surfing, look for one with PC connectivity. Many TVs today offer these additional features.
LCD or Plasma?
Debating between LCD or plasma can almost get as subjective as debating between chocolate and vanilla. But unlike the never-ending ice cream debate, there actually is a superior TV choice, depending on how you plan to use it.
Check out some of our previous guides on the subject to get a better look, but in short, plasmas use more electricity, come in bigger sizes, have deeper blacks, don’t suffer from motion blur, and offer an unlimited viewing angle that’s best for off-axis viewing. LCDs are more energy-efficient, have fewer problems with glare due to their matte screens, can hold an image for hours or days without suffering “burn-in,” and generally look brighter.
What are widgets?
Many of the top television manufacturers – including Sony, Sharp, Panasonic and Samsung – include Ethernet jacks on the back of their premium televisions for high-speed Internet connectivity (or in some cases, have integrated Wi-Fi for wireless connections). TV viewers will then use the remote to select “widgets,” graphicalicons on the screen that plays relevant (and customized) content ranging from YouTube videos and Flickr photo galleries to local weather, news, sports updates and stock quotes, usually delivered by Really Simple Syndication (RSS). Even more exciting is the partnership between Netflix and various TV companies, such as LG and Sony, allowingtelevision viewers to access tens of thousands of movies on-demand, many of which are in high-definition.
