• Turn on the HDMI sources and displays. Turn on the matrix and after a pause
for HDCP handshaking, observe the source signals on the displays. The HMX-
144 front panel LEDs light, indicating the active sources in each zone, HDCP
status and HDMI/DVI status.

on the use of high quality HDMI cables with low loss, high bandwidth signal
handling capabilities. The distance specification cannot be guaranteed unless
cables used throughout the system meet these high standards.
