Dear Harmar, thank you for your question and Branpute thank you for creating the diagram!
Do you have more information about the monitors you are using and HDMI splitter you intend to use? The max number of monitors you can use is limited by the bandwidth of the DP output which allows for example 3x 1920x1200p monitors at 60 Hz.
That being said, we have not tested a setup as pictured above ourselves so we can’t tell for sure if it works. It will likely exceed the bandwidth first though.
