Gefen – 4K Ultra 1:2 HDMI Splitter


4K Ultra HD 1:2 HDMI Splitter

The Gefen GTB-HD4K2K-142C Ultra HD HDMI Splitter routes one Ultra HD source to two 4K Ultra HD displays. It eliminates the lengthy HDMI authentication process, and allows disconnecting, reconnecting, or powering down HDTV displays without any of these activities causing picture loss in other displays within the same distribution system. The choice between built-in and passed-through EDIDs, and the ability to configure the EDID for 2-channel or multichannel operation help customize your AV system to meet its operational requirements . The Gefen 1:2 Splitter is a high performance and capable choice for any small or large 4K video distribution system. This product features Fast Switching Technology (FST). FST is a Gefen firmware implementation for HDMI products.
