Smart TV with Web Connected Apps
Samsung Smart TVs allow you to easily search for movies, TV shows, explore Samsung apps, chat with friends and find many other types of new interactive TV content. Samsung Apps is a growing collection of premium apps specifically built for your TV that connects you to your favorite digital content such as movies from Netflix or Blockbuster, TV shows from Hulu Plus, videos from YouTube, Next Level sports information from ESPN, Music from Pandora, and social updates from Facebook or Twitter. Samsung’s Smart TVs also include a Search All feature so you can find videos via apps or other connected devices and a recommendation engine which suggests movies you might like from your Video-On-Demand services. Samsung Smart TVs allow your digital experiences to converge on a brilliant HD screen.

Experience the wonder of 3D TV
3D TVs add new depth and dimension to create larger-than-life experiences. 3D Active Glasses sync up with the 3D TV to produce 3D images that virtually leap off the screen. Samsung 3D TVs also offer a unique feature that allows you to intensify your 2D viewing by upconverting 2D content to a near 3D like experience.*

* Full 3D experience requires 3D-native content; conventional 2D content can also be upconverted to near-3D image quality.

Great 2D Full HD Picture Quality
See the difference that 1,920 x 1,080 – the highest resolution available – makes in your viewing experience. A breathtakingly realistic picture that’s bright, bold and visually stunning.

Clear Motion Rate 480
Clear Motion Rate (CMR) is Samsung’s more comprehensive and accurate measure for how well an LCD or LED TV can display fast-moving images. Previously, motion clarity was expressed simply by the refresh rate, measured in Hz. CMR, however, takes into account all three factors that contribute to motion clarity: panel refresh rate, image processor speed and backlight technology. CMR is measured by determining the thinnest line a TV can display in a moving image. The thinner the line, the higher the CMR rating, and the clearer the picture you’ll enjoy on the screen.

AllShare™ DLNA® Technology
Samsung’s AllShare lets you sync up many of your DLNA-enabled digital devices so you can access music, movies and photos right on your Samsung TV screen. Files on your PC, camera and mobile devices can wirelessly and effortlessly be available right on your TV.

*Samsung LinkStick required for wireless access.

ConnectShare™ Movie
ConnectShare Movie lets you watch videos, play music or view photos from a USB drive. Simply plug your USB directly into your Samsung TV’s USB port and watch on the big screen with friends and family.

Ultra Clear Panel
Ultra Clear Panel absorbs ambient light and virtually eliminates reflections so there are no distractions in your viewing experience. Experience deeper blacks and enhanced contrast for crisper images and excellent shadow detail on your Samsung LED.

Wide Color Enhancer Plus
Wide Color Enhancer Plus allows you to see picture color the way the director originally intended. Witness the entire RGB spectrum brought to life on your screen to bring you exceptionally vibrant, yet natural-looking images faithful to the director’s original intent.

Eco Sensor
Our unique Eco light sensor measures the intensity of the room’s light and automatically calibrates the brightness of the image on the screen. In a sun-filled environment, the screen gets brighter and in dim surroundings, the intensity is reduced. This feature optimizes the viewing experience while also saving you a little energy.

Swivel Stand
Set up your Samsung TV perfectly with the built-in swivel stand. Samsung Swivel stands allow you to turn your TV around 10 degrees to the left or right to ensure you have a direct view of the TV no matter where you are sitting in the room.

Take all your remotes and condense them into one simplified solution. With Samsung’s Anynet+ you’ll enjoy one-touch control for all your HDMI-connected compatible devices like your Samsung TV, Blu-ray Disc player, AV Receiver and Home Theater.

With HDMI, you can easily connect up to four compatible AV devices at the same time and replace AV cables with a single solution. An HDMI cable can replace anywhere from two to five cables so you can de-clutter your entertainment space with fewer wires.
