Dell - Precision 3541 with INNOCN 49" WDQHD Ultra Wide Monitor

Hi, I just ordered a Dell Precision 3541 laptop with a NVIDIA Quadro P620 graphics card.  Also, I was looking to get a INNOCN 49" WDQHD Ultra Wide Monitor which has a max resolution of 5120 x 1440 (5k HDR) with a refresh rate of 120Hz.

If I also get a WD22TB4 docking station, will I be able to display that 5120 x 1440 resolution with a refresh rate of 120Hz?  Assume that I will only display to the INNOCN monitor (no additional monitors, laptop closed) and will use a display port cable.

I thought the WD22TB4 docking station would be a better choice since it seems to support 5k, where as the WD19 docks can only support 4K.

Thank you for your support.
