“HDMI In” port of the Distribution Amplifier.
3. Connect the HDMI cables from the outputs of the distribution amplifier to the inputs
of the monitors.
4. Power up the Distribution Amplifier and the Monitor connected to HDMI output
number one on the amplifier. Leave the other monitors off for now.
5.Turn on power to the source device. The monitor connected to output number one
should have picture and sound within about 5 seconds.
