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.
Using Fast Mode

Basic Operation
Setting the EDID Mode
The 4K Ultra HD 1:4 Splitter for HDMI features EDID Management. Before the source can
send video and/or audio to the display (sink), the source reads the EDID (Extended Display
Identification Data) from the display (sink) devices connected to the splitter. The EDID
contains information about what type of audio/video data that the source can send to each
output device. The splitter can use either the downstream EDID (from the display/sink) or
the built-in internal EDID.

1:4 Splitter
for HDMI
Using the Internal EDID
Use this EDID mode if problems are encountered when using the external EDID.
The built-in internal EDID provides the source device with a “generic” EDID which can
be used by all display (sink) devices. The use of the internal EDID also provides control
of the audio output format. See Setting the Audio Channel Mode (page 10) for more
information.

Using the External
for HDMI
When set to Ext mode, the splitter will fetch the EDID data of each display (or other sink
device) that is connected to the splitter. Once this information is gathered, the splitter
“builds” an EDID based on the highest video resolution and most superior audio format
that is supported by all Fast
sink devices. This EDID is then transmitted to the source device.

Surface Mount Instructions
The 4K Ultra HD 1:4 Splitter for HDMI should be mounted vertically in a wall or cabinet
with wood/drywall screws as shown in the diagram above. There should be an inch or two
of clearance between the edges of the unit and any walls or vertical surfaces to allow for
enough clearance for insertion and retraction of cables at the HDMI connectors.
For installation on a drywall surface, use a #6 drywall screw. It is recommended when
installing on a drywall surface that studs be used to secure the splitter should undue stress
be applied when connecting and disconnecting HDMI cables.
