USB-C Video Inactive on z24n

HP Recommended
z24n
macOS 10.15 Catalina

I have a new (2020) MacBook Air, which shipped with a Thunderbolt / USB-C cable.  I just unboxed the z24n display and used that USB-C cable to connect my laptop to the display.  I can't get the laptop to see the display or vice-versa. I've used a few different cables. I read in an old thread that my cable may not transfer data, but I think that isn't the case now. I believe new MacBooks ship with the latest USB-C technology, capable of display. I also read about selecting Performance Mode in the Power Menu, but that also did nothing.  Any ideas?

 

Also, I should note that when I plug my laptop into the display, I get the familiar 'ding' that comes with the laptop charging.  So I know there's at least a charging connection there.  

 

(I've been using the USB-C port on the back of the display.)

 

Also, when I go into Sys Pref / Display / Option - Detect Displays, nothing happens.  The two devices aren't able to see each other from a data perspective.  Any ideas?

I believe the USB-C cable that ships with the the laptop is for power only.  It does not carry data.

 

You will need to purchase a USB-C 3.0/3.1 cable or Thunderbolt 3 cable to transfer data/video to the monitor.
