Hi Jamie,
Thank you for contacting us, I am sorry this is not working as expected and I am happy to help!
The UD-3900PDZ USB-C Triple HDMI Docking Station’s HDMI 1 output port relies on USB-C DisplayPort Alternate Mode, or “Alt-Mode” for short, this is an optional USB-C feature that is not supported on all computers or by all USB-C cables.
Our first step is to make sure the docking station is connected to the computer using a compatible USB-C data cable that supports Alt-Mode video. Please connect the docking station directly to the computer’s USB-C port using the USB-C cable provided with the UD-3900PDZ docking station. USB-C “charging” cables or cables from other devices may not support Alt-Mode video, additionally adapters, hubs, and cable extensions may not support Alt-Mode video. Please let me know if this enables the HDMI 1 output port.
If not our next step is to check to verify that the computer supports USB-C DisplayPort Alternate Mode, for computers running Windows:
If this is an Apple computer:
Thank you for these additional details, I look forward to your reply.
