KB01545: How to Independently Route to HDMI Outputs on the AT-UHD-PRO3 Matrices


Subject: How to Independently Route to ALL Outputs on the AT-UHD-PRO3 Matrices

Challenge: Inputs cannot be routed to HDMI outputs


By default, the HDMI outputs of AT-UHD-PRO3 matrices are configured for Mirror Mode and will follow the routing of associated HDBaseT outputs. For instance:

AT-UHD-PRO3-44M: HDMI output 5 mirrors HDBaseT output 4.

AT-UHD-PRO3-66M: HDMI outputs 6 and 8 mirror HDBaseT outputs 5 and 7 respectively.

AT-UHD-PRO3-88M: HDMI outputs 8 and 10 mirror HDBaseT outputs 7 and 9 respectively.

AT-UHD-PRO3-1616M: HDMI outputs 17-20 mirror HDBaseT outputs 13-16 respectively.

From the AT-UHD-PRO3 manuals:

I/O routing includes mirror mode for the HDMI ports.

Mirror Mode:

On HDBaseT outputs are selectable from the drop down menu. The HDMI port will output the same audio and video of the selected HDBaseT output

Off (Matrix Mode)Any of the connected inputs are selectable from the drop down menu. The HDMI port will output audio and video from the source to a local display.

To disable Mirror Mode and allow independent routes to HDMI outputs:

  1. Access the WebGUI for the AT-UHD-PRO3 matrix
  2. Navigate to the Configuration: I/O Tab
  3. On the HDMI Outputs, toggle the Mirror Mode drop-down selectors from On to Off:

  4. The Output drop-down selector will then change from reading "Output_#" (the HDBaseT output this HDMI output was mirroring) to "Input_#":

Mirror Mode has been successfully disabled, and you can now independently route to HDMI outputs.
