This complete transmitter and receiver system is recommended for video presentations in conference rooms, schools, trade shows, meeting facilities, houses of worship, retail settings and digital signage applications where the source and display are farther apart than conventional AV cables allow. The B127F-1A1-MMDDA extends 4K video and stereo audio signals from a DisplayPort (DP) source device to a DisplayPort monitor up to 985 feet (300 meters) away via user-supplied duplex multimode LC fiber cabling. The B127F-1A1-MMDDA supports Ultra HD 4K video resolutions up to 3840 x 2160 at 60 Hz with full, rich uncompressed DTS-HD, Dolby AC-3 and 8-channel LPCM digital audio. Built-in equalization automatically fine-tunes the image quality at the remote display with no time-consuming manual fiddling needed. It supports HDR (High Dynamic Range), providing a wide range of vibrant colors with richer contrast, brighter whites and deeper blacks that pop on your 4K display. HDCP 2.2 encryption allows you to stream 4K content with no complications. This extender kit also supports uncompressed 4:4:4 chroma subsampling for top-level PC gaming or using your HDTV as a PC monitor.
