Question about i-tec Dual Display

I bought the dock for my Surface Book 2 and an HP notebook. On the HP notebook, the 4K monitor is addressed at 60Hz without any problems. As soon as I connect the dock to the Surface Book 2, I only have 30Hz available. Can anyone give me a tip on how to get to 60Hz? Is it not possible with this dock or have I overlooked something? If it doesn't work with this dock, is there an alternative? Many thanks in advance.

It depends on how the connection is established. Even if you connect your notebook via USB-C/Thunderbolt to your docking station, the transfer of the image runs according to one of the known protocols such as HDMI 1.x or 2.x or DisplayPort. For example, my HP notebook can handle 3440x1440 @60Hz with DisplayPort connection between docking station and screen. But if I connect the docking station and the screen via HDMI, then the protocol between notebook and docking station is of course also HDMI, then only 50Hz works. The reason is that the graphics chip of the notebook is not able to process more via HDMI protocol. Only via DisplayPort, which is fortunately supported via the USB-C connection.
