Samsung 40” LED 4K Ultra HD Smart TV with Built-in WiFi (Refurbished)

Samsung’s 4K Ultra HDTV presents everything from movies to live sports in stirring detail. Even better, it upscales non-4K content to near-4K resolution, including shows you stream over the TV’s built-in apps.

Samsung Smart Hub: Your HDTV’s Control Center
Samsung’s Smart Hub makes streaming movies, viewing photos, and even checking out social media quick and easy. Apps such as Netflix and Hulu Plus are laid out like on a smartphone or tablet, so you can quickly get to the content you want. The Smart Hub’s wireless networking lets you share connected mobile devices’ pictures and videos on the big screen, as well as access news and Facebook posts.

Rich, Cinematic Picture
4K Ultra HD resolution supports an almost uncannily realistic picture. 4K refers to Ultra HD’s more than 8 million pixels—about four times as many as 1080p Full HD resolution—which saturate the display so completely that images retain their lifelike detail regardless of how close or far you are from the screen. This pixel density also supports heightened picture quality for non-4K content.

Enhanced Brightness and Depth
LEDs boost brightness, creating a brilliant picture that’s easy to see whether you’re curled up for a late movie or getting ready for a noon kickoff. Striking black and white levels give images more pop, contribute to a more realistic sense of depth, and amplify shadows and other lighting effects. LEDs also consume little power, making them more energy efficient than other forms of display lighting.

HDMI and USB: Connect to More Content
An HDMI port connects high-definition components such as a Blu-ray player, cable box, or Roku Streaming Stick directly to your HDTV. USB input pushes your TV’s connectivity even further, letting you do things such as view photos or listen to music saved on thumb drives, digital cameras, and other USB sources.

About Samsung

In the 70 years of its existence, Samsung has grown into an international company with interests spanning from home electronics to skyscraper construction. The company takes its global role seriously, working to improve communities with both its financial support and the expertise of its talented employees. The company’s Solve for Tomorrow competition, for instance, challenges kids to create videos that demonstrate how science and math can be used in new ways to improve their local environment. After screening the videos of thousands of worthy entrants and dozens of confused American Idol hopefuls, Samsung chooses five winners, whose schools each receive $110,000 in technology. Solve for Tomorrow is just one of the company’s outreach initiatives, which align with its philosophy: to help build a “better global society.”

First one had a cracked screen, the replacement has half of the screen dark. At this point the cost to return a second time exceeds what I paid Very sad...
