1394D distributes Ultra High Definition resolutions up to 4096x2160@60Hz from one source to four HDMI displays. Standard/TV EDID settings enhance compatability between source and displays. This feature is especially useful in the retail demo environment, where multiple brand and model TVs all receive the same source signals. The 1394D passes 3D signals. Bitstream audio is also supported - including LPCM 7.1 channel uncompressed audio, Dolby Digital TrueHD (7.1), DTS HD: Master Audio (7.1), and Dolby Atmos (7.1.4). Legacy codecs such as Dolby Digital and DTS core are also supported.
