HP z27n g2 delivering power but no signal through USB-C

HP Recommended
HP Z27n G2
macOS 10.14 Mojave

Howdy. I have two HP Z27n g2 monitors and a 2019 MacBook Pro running Catalina 10.15 (not an option in the dropdown). Everything works fine for one monitor using the USB-C input. But the other will only deliver power through the USB-C port, not a video signal.

 

Identical set up (same cable, same port on the mac, etc) works on my other Z27n G2 (tho' I purchased them at different times), and the Mac recognizes the problematic monitor with an HDMI input. The port is on (energy saver mode is off). I do get an "unsupported cable" message on both monitors, but it still works on the one. It must be an issue with that monitor's settings somehow. Thoughts?

 

Note: I'm not trying to run two monitors at the same time. I mean, I am, but that's not the issue. The problematic monitor will not work by itself.

 

Thanks so much!
