P3424WEB, USB-C hub not picking up 2nd monitor DP-DP

I recently purchased the P3424WEB (34" curved conference monitor with USB-C hub).

I am trying to connect a second monitor (Dell: 3 years old) to the new monitor via DP-DP. I also have the USB-B to USB-A cable plugged in.

My computer picks up the USB cable in the 2nd monitor but it doesn't pick up the 2nd monitor in display settings. 

I am running the new monitor via the USB-C cable provided with the monitor on a Microsoft Surface Studio 2 (RTX 4050 Laptop GPU w/6GB Ram). All drivers are up to date and I reinstalled them as well.

My questions are:

- Can the new P3424WEB have an additional monitor connected or does it have to be another computer?
- Does the new P3424WEB have to have a certain type of monitor it needs to connect too?
-Is it a limitation of my laptop itself?

Any help will be gratefully received. Thank you :)
