The UN40D6420UFXZA by Samsung LED 3D HDTV Set Will Greatly Increase Your TV Enjoyment

The UN40D6420UFXZA Samsung LED HDTV with 3D is loaded with advanced features. It is packed with technology that won't just improve your television watching experience, but will give you access to almost every other type of media as well, whether it is on the Internet, or in folders found on your computer or on your other media devices. When combined with the outstanding picture quality from its HDTV LED screen, you are assured of having a total home entertainment adventure.

Samsung has been a force in the development of flat screen HDTV televisions; it is just about the top manufacturers on the market. Samsung's latest models feature Light Emitting Diode back-lighting , which replaces the outdated fluorescent tube methods which were employed in the early generations of LCD TV sets. The development of this LED back-lighting technology has made it possible for them to manufacture televisions that are thinner, and lighter than earlier sets, yet provide significantly higher image quality . The UN40D6420UFXZA Samsung LED HDTV with 3D is an excellent example of this technological brilliance.

The Samsung UN40D6420UFXZA LED 3D HDTV set uses an "edge lighting" method to supply back-lighting for the LCD display. In this method of back-lighting, very bright white-light Light Emitting Diodes(LEDs) are set along the edges of the display . A diffuser plate then spreads the luminescence from the LEDs across the entire surface of the display. The use of the LED light system results in the TV requiring much less electricity to work. This TV set is extremely efficient: based on a usage interval of 5 hrs per day, and a cost of electricity of $0.11 per Kwh, it will only cost you around $14/year to operate this set. If the tv set is off, it consumes only 0.07 Watts of power. That amounts to 0.6 Kwh/yr, which is less than $0.07 per year, based on the very same power charges !

HDTV Television sets with 3D capability represent the cutting edge of entertainment technology. This new wave is growing at an impressive rate, with the amount of 3D content growing at an increasing rate. Whether you get your TV signals from FIOS, XFinity, DirecTV, or others, or just want to watch the latest movies on DVD, there is a rapidly growling library of 3D programming at your disposal. As this 3D entertainment tsunami grows ever larger, your options will become almost unlimited.

The biggest choice you will face in getting into the world of 3D entertainment is: "Which 3D method should I embrace?". If you are at all familiar with 3D HDTV technology, then you are probably aware that there are two distinct ways to create a 3D television program: "Active", and "Passive". The Active method uses glasses with LCD lenses that switch on and off to block each of your eyes as the different 3D frames are shown on the screen. The Passive method relies on polarized glasses with lenses that are polarized in two directions, so that each eye sees only one half of the lines on the screen...and that tells the tale right there!

When you watch a 3D program on a set that uses the Passive method, each of your eyes will only see one-half of the lines on the TV screen. The reasons are a bit too detailed to get into in this hub, but you can find a more complete explanation here. Suffice to say that it does not seem to make a lot of sense to get an HDTV set that gives you 1080 scan lines per frame, and then be able to see only one-half of those lines when you watch a 3D program.

The picture on the right shows an enlarged portion of a Passive 3D image on an HDTV screen. If you look closely, you can see that the two images are actually made up of alternating horizontal scan lines on the screen. The reason for this is that when you are wearing the polarized glasses, each of your eyes will see only one of those two different sets - which is what produces the 3D effect - so you are actually "seeing" an image which has just 580 scan lines, instead of the 1080 lines that you see when you watch an HDTV image without the polarized glasses.

With an Active 3D system - which Samsung uses - each of your eyes sees the entire set of 1080 scan lines. This is because the two different images needed to create the 3D effect are shown one after the other. As the image for your right eye is displayed, the Active glasses you are wearing turn dark over your left eye, so it cannot see that image. Then, in the next instant, the image for the left eye is shown, and the lenses reverse, with the right lens dark and the left one clear.

This means that each eye sees the full set of scan lines (and thus the full hi-resolution image) at all times, and you will not suffer a loss of resolution while you enjoy a 3D presentation. Samsung has two different models of 3D glasses, one of which uses replaceable batteries, and the other (more expensive) model uses a rechargeable battery, which is recharged by connecting the glasses to a USB port. This model is extremely light, weighing less that one ounce!

Samsung's superior Active 3D system is just the tip of the iceberg when it comes to describing all these sets have to offer - but before I leave that subject there is one more detail that is important: With a Samsung Active 3D set, you can actually "Up-Convert" regular 2D programming to a "near-3D" appearance! It's not "true" 3D, but the programs actually develop a sense of depth.

There is a long list of additional features that come with the UN40D6420UFCXZA. Just for starters, there are the "Smart Apps" - all kinds of programs that run on the TV set. These apps cover a wide range of subjects including Lifestyle, Videos, Sports, Education, Information, and Games - not to mention giving you access to services like Pandora, Hulu, Netflix, and others.

Then, there are things like the ability to interface with your home wireless network by adding the Samsung LinkStick, the superior energy efficiency that makes it possible to operate the set for less than $20/yr, the ConnectShare movie feature, Micro Dimming, the Ultra Clear Panel, the Eco Sensor, and so on.

When you are ready to take the step into the world of 3D, this is one set you really need to check out!
