The GefenToolBox 1:4 Splitter for HDMI with FST and 3DTV sends a Hi-Def A/V source to up to 4 HDTV displays at the same time without losing quality or resolution. This product works with any Hi-Def source supporting resolutions up to 1080p Full HD with 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 was created to improve the lengthy HDMI authentication process, based on the HDMI and HDCP specifications. FST provides quicker A/V source switching and greatly improves the overall A/V system behavior and performance when more than one HDTV display is used in the system setup. FST allows connecting / disconnecting or turning ON / OFF the HDTV displays without having these activities affect other displays in the same distribution system.
