dual monitor resolution issue

I have a Surface Laptop with a Ryzen 5 CPU and a Vega 9 GPU running Windows 11.  I just purchased a second monitor (Dell 2721QS 4K) to go along with the Dell 2715 QHD monitor to achieve a dual monitor workstation setup.  Both monitors are connected via USB-C from the laptop to a USB 3.0 hub adapter (docking station), with HDMI cables from the adapter to each monitor.  The system will allow me to run the older 2715 monitor at QHD resolution (2560 X 1440), but will not allow me to run the 4K monitor at anything higher than HD resolution (1920 X 1080).  All drivers are current.  I would like to run the new monitor at full 4K resolution, or at least something higher than HD.

 

TIA

    hello, in order to get the dual monitor resolution on 4K, please ensure the USB C port of the laptop support DP 1.4, the DisplayPort of the dock support 4K when extending the dual monitor, and the cables which connect to the dock, and the laptop support 4K. Otherwise, you would not get 4K. hope this help.
