  Purchased an HP Pro Desktop 400 G9 SFF Business Desktop Computer which can handle 2 4K monitors.  I wanted to add a third monitor and so purchased the Selore & S-Global USB C Docking Station as I was assured this docking station would handle my needs.  So far no sucess.  I am looking for recommendations on how to make this marriage work, any suggestions?

  Hi @Chuck Hoose,

  Thanks for the information you provided.

  To better solve your problem, please confirm and provide the following details:  

  1. Please get in touch with HP's official customer service to confirm whether the computer's C port supports video.

  2. Please provide a clear overall connection diagram (including the computer, monitors, and the docking station) to confirm whether the connection is correct.

  3. Open the display settings and check whether the monitor connected through the Selore docking station is recognized in the display settings. （Provide the photo）

  Looking forward to your reply.

  Best regards
