7. Advanced Configurations
Using an HDMI Extender:
To extend the distance between your HDMI source and the video wall controller, an HDMI extender can be used. Connect the HDMI extender transmitter (TX) to your source, and the receiver (RX) to the HD0112's HDMI input. Use a CAT-5e/6/7 cable to connect the TX and RX units.
