Reset Button
The HDMI Audio/Video Splitter has a built-in reset button. Press this
button if the audio/video source from your HDMI-enabled video
source device is disrupted or lost on any of the connected HDMIenabled video display devices.
EDID Emulation
This splitter features EDID emulation enabling you to choose the
best vide source settings available from any of your connected
displays.
The EDID video source settings are selected based on the rst port
that the switch detects the use of beginning with port 1. Once the
EDID display settings are dened all other EDID information from
additional display(s) will be ignored. Please follow the below steps to
specify your EDID selection.
1. Disconnect the power source to the splitter.
2. Determine which display has the preferred EDID settings to be
shared with your video source.
3. Plug your preferred EDID display into port 1 of your HDMI splitter
and ensure this display remains connected at all times.
4. Connect your remaining displays to the splitter, and power the
splitter back on.
The EDID settings have now been set.
Note: If the splitter is rebooted or loses power, EDID settings will
be rescanned and reselected. To avoid this scenario causing your
preferred EDID settings to be lost, it is recommended you connect
your preferred EDID display to Port 1 at all times.
