***** Start watching true 4K content on your F9000 TV ***** The SEK-2500U replaces the One Connect Box originally included with Samsung's F9000-series TVs. This upgraded box is compatible with Netflix's 4K streaming, & can display 4K content when connected to Samsung's UHD media player. The SEK-2500U demonstrates the genius of Samsung's One Connect Box design. Physically, this box is virtually identical to the version that came standard with F9000-series Ultra HD TVs. The F9000 models do a great job of upconverting HD content, like Blu-ray, but aren't compatible with 4K sources that have become available recently. The SEK- 2500U updates the box's digital connections with four HDMI 2.0-compatible inputs. The box's innards now include HEVC decoding, which is necessary for watching streamed 4K content from Netflix® & other video services. Last, but not least, the SEK-2500U houses a more powerful Quad Core Plus processor that runs about twice as fast as last year's version, for speedier web browsing & app multitasking. ***** Highlights: ***** * means that you can update 2013 Samsung F9000-series Ultra HD TVs, to provide access to current & future sources of 4K content * replaces the F9000's original One Connect Box & connects to the TV using the same proprietary cable * HEVC for compatibility with streamed 4K content from sources like Netflix® (requires Internet connection speed of at least 20 Mbps) * more powerful Quad Core Plus processor for faster web browsing, quicker access to online applications, & greater multi-tasking capability * 14-3/16"W x 1-1/16"H x 5-1/8"D
