  • Product Description

    1x4 4K capable HDMI Distribution Amp with Ultra HD resolution, HDMI 2.0, FST and EDID management. 

    The GefenToolBox 1:4 Splitter for HDMI 4K x 2K distributes one Ultra Hi-Def A/V source to four Ultra HD displays simultaneously, without loss of quality or resolution. This product works with any Ultra Hi-Def source and supports resolutions up to 4K (3840 x 2160 @ 60Hz 4:2:0) and 4K Cinema (DCI) (4096 x 2160 @ 24 or 30Hz 4:4:4).It features Fast Switching Technology, and supports HDCP, Deep Color, 3DTV pass-through, and lossless audio formats such as Dolby® TrueHD and DTS-HD Master Audio™.


    Fast Switching Technology (FST) is a Gefen software implementation for HDMI products. FST eliminates the lengthy HDMI authentication process, and allows connecting/disconnecting or turning ON / OFF of HDTV displays without having these activities affect other displays in the same distribution system.

    How It Works

    Using the supplied HDMI cable, connect the Ultra Hi-Def source to the HDMI input on the 1:4 Splitter. Connect up to four Ultra HD displays to the HDMI outputs. Connect the included locking power supply to the 1:4 Splitter and to an available electrical outlet. Apply power to the source and displays. The HD source signal will now be seen on all of the connected displays simultaneously.
