Using Dell WD19TBS with 14" MacBook Pro M1 with 2 external monitors?

I am trying to use the docking station with my M1 MacBook pro and am having issues. I can connect, but my 2 external monitors just mirror each other - how do I make them both act as additional screens? I don't want them mirrored



MacBook Pro (M1, 2020)

SOLUTION FOUND: for anyone that stumbles upon this with the same issue, you need to have 1 DP to DP cable for the first monitor, and a DP to usb/thunderbolt cable for the second monitor. I previously had DP to DP twice, and since getting a DP to usb/thunderbolt cable the issue is now fixed!

The Mac can support up to two displays on one cable out of the Mac ONLY when the port and the cable are genuine Thunderbolt , and the first device is a genuine Thunderbolt device (Dock or Display).


Connecting with only a USB-C cable will NOT work on a Mac, regardless of whether your Windows computer supports it.

sorry, I wrote that wrong:


Problem:

The video on the attached monitor is not displaying as an Extended Monitor.


Suggested solutions:

  • Ensure that the Intel HD Graphics driver is installed in the Windows Device Manager.
  • Ensure that the nVidia or AMD Graphics driver is installed in the Windows Device Manager.
  • Open the Windows Display Properties and go to Multiple Displays control to set the display to the extended mode.

Hi Grant, thanks for the info. So if I get a thunderbolt cable and connect from my Mac to the dock, will it work? Or am I misunderstanding? Thanks


Edit: sorry I just realised that my MBP doesn't seem to have a thunderbolt port - only USB C. How can I make this work? Sorry I'm a bit confused

Hi Grant, the input cable does have a thunderbolt symbol - I've tried to attach a photo but it keeps failing.


You can see what the cable looks like here: https://www.ndc.co.uk/media/catalog/product/cache/3f9fa13c20827c5a85b5b37421c55530/b/6/b6034_dell_wd19_wd19s_series_docking_station_cable_upgrade_module_j4w65.jpg
