This complete transmitter and transceiver system is recommended for video presentations in conference rooms, schools, trade shows, meeting facilities, houses of worship, retail settings, hotels and other digital signage applications where the source and display are farther apart than conventional AV cables allow.

The B127A-111-BDTDA supports Ultra HD 4K resolutions up to 3840 x 2160 at 60 Hz with 7.1-channel surround sound via the transceiver’s TOSLINK audio output. Built-in equalization allows you to fine-tune the image quality at the remote 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.
