Samsung UN55D8000 55-Inch 1080p 240Hz 3D LED HDTV

in Electronics

The Samsung UN55D8000 3D HDTV continues Samsung's move to bring high levels of video technology to home theaters everywhere. It is an active system that relies on some interesting technology to make things happen. First, the UN55D8000 is one of Samsung's top-of-the-line "smart TVs," powered by a microprocessor.

It is undoubtedly a microprocessor-controlled device when one just looks at the features the UN55D8000 offers. Here's just a sample of what one finds when one opens the box and removes the ultra-thin 55-inch high-definition receiver out of its box (1.2 by 48.5 by 27.8 inches with a diagonal picture size of 55 inches): the ability to maximize and enhance standard 2D television to where it seems to be 3D; 3D content with the proper glasses, and high-definition television. In addition, the UN55D8000 offers DLNA-compliance (Digital Living Network Alliance, a number of electronics firms that have come together to ensure that their products work together as seamlessly as possible), as well as wired networking capability through an RJ-45 connector and full WiFi connectivity.

That's quite a bit of capability to build into a television receiver, as well as the ability to access the Web, social networking sites such as Facebook or Twitter and the ability to connect through Skype an online-based VoIP (voice over internet) video and audio product. Since these features are linked together one can infer that there is a microprocessor controlling the UN55D8000. It's the only way to explain all of the functionality built into this high-definition television receiver.

It goes without saying that the UN55D8000, a top-of-the-line Samsung receiver, offers the wide variety of features that are standard in high-definition television receivers. The native resolution, for example, is 1080p, which is the standard native resolution of all high-definition receivers. The actual resolution at which the UN55D8000 is 1920 by 1080, operating at 240 Hz (more about this in a moment). It also operates at a standard 16:9 video ratio, again, another giveaway that there is more to this 55-inch receiver than meets the eye.

Even more proof can be seen by the tine one-inch bezel that surrounds the glare-free black screen so that when the UN55D8000 is turned off one can barely see the receiver's surround. Built into this surround, though, one finds HDMI inputs, as well as the PC networking interface and standard video output. With four HDMI inputs one can interface a variety of high-definition-capable devices such as blu-ray players that deliver 3D in the 3D mode or fine 2D video.

The UN55D8000 is compatible with home networking 5.1 surround sound and offers very fine picture quality, delivering deep blacks, crisp whites and vivid colors. It's 25,000,000:1 contrast ratio assures one of the best viewing possible, as does its 3D capability.

The UN55D8000 operates at a higher-than-standard resolution of 240 Hz for a very specific reason, to bring one a fine 3D experience with clear images with none of the visual artifacts or haloing normally associated with LCD displays. The UN55D8000 works with "smart 3D glass" technology to deliver fine 3D pictures.

The way this technology works is this. Normally, the eye is comfortable viewing 60 Hz items - about 15 frames per second. In this mode, nature makes our brains understand that the items we see are further or nearer and completes the images we see. In order to see things in 3D, one has to start playing games with video resolution and Samsung has found that by operating at 240 Hz and using active shutter technology on its 3D viewing glasses, which are synchronized to the video display by small signals to each pair, one gets the best overall 3D effect.

The way active shutter technology works is actually quite simple. Although one doesn't notice it, one lens of the glasses is turned off while the other is turned on briefly so that each eye sees the same scene but from a slightly different angle at a slightly different time - we're talking about milliseconds here. Meantime, the UN55D8000 boosts the signal so that the contrast is heightened and the colors are made crisper and brighter. The backlit LED helps to ensure that the video is fine and your 3D experience is heightened as well.
