What is Fast Switching Technology?
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 audio/video source switching and greatly improves the overall audio/
video system behavior and performance when more than one HDTV display is used in the
system setup.
FST allows connecting / disconnecting or turning ON / OFF of HDTV displays without
having these activities affect other Hi-Def sources routed to any other HDTV display in the
same system.
Fast Mode vs Slow Mode
Use fast switching mode to improve performance when connecting / disconnecting Hi-Def
sources, and powering ON / OFF HDTV displays.
Use slow mode when the source does not support multiple devices. When set to slow
switching mode, the 4K Ultra HD 4x2 Matrix for HDMI will follow the standard authentication
process, based on the HDMI and HDCP specifications.
Selecting the FST Mode
1. Press and release the FST button, using a paper clip or other pointed object,
to toggle between Fast and Slow modes.
2. The LED indicator will display the current FST mode.
