Pavilion 27xw stays black with boot up as a secondary display to an iMac 27" macOS 10.15.6. The HDMI cable is plugged into a Thunderbolt 2 to HDMI adapter, and that adapter is plugged into another adapter (USB-C to Thunderbolt 2 adapter) that is plugged into the USB-C socket on the iMac.

@lradler  Welcome to HP Community!

 

Here's a few things you need to know when using an HP monitor with a Mac device:

HP monitors are not supported in a Mac environment. However, newer Macs use graphics with VESA modes and can display to most HP LCD monitors.

  • To do this, connect the monitor to the Mac while the Mac is off, and then turn on the MAC.
  • The monitor should operate at 60Hz.The INF and software for the HP monitor are for Microsoft Windows and cannot be run in a standard MAC OS environment.

P.S: Welcome to HP Community 

 

I hope that answers your query,
