Installation and Operation
Before permanently securing the unit for final installation of cabling behind walls or ceilings, test
for proper operation of the unit and the cables in your system. It is recommended that you leave
enough ventilation space to provide sufficient airflow and cooling, especially if you are going to
leave the unit powered at all times.
Active Input / Output LED Indicators
½
The front LED indicators indicate that a valid HDMI / DVI-D
connection is made between the KD-HDRV unit and each
Input / Output.
EDID Control Settings
At times, your HDMI sources and display may not synchronize
properly. This is when EDID* control should be utilized. KD-
HDRV Distribution Amps feature an internal library of default
settings that ensure that your HDMI source’s output is
compatible with the display devices.

All Others
Highest common EDID of output devices
Example of EDID Auto Select:
If one of your system’s displays supports 1080p, however the second display only supports up to
1080i (does not support 1080p), then the highest common EDID format supported is 1080i. By
choosing the Auto Select EDID Setting, your KD-HDRV unit will inform your source device to output
1080i in order to ensure that all displays receive a supported signal.
* EDID (Extended display identification data) is a data structure provided by a display to describe its capabilities to a
source device.
