Thanks for pointing me to that page, I didn't catch that flag. I added
those in although I still get the lack of signal upon wake, sadly. It'll
probably prevent jankiness elsewhere though. My next step is trying an
active HDMI to Displayport adapter.

My active HDMI to Displayport adapter just happened to arrive and it seems
to solve the problem. I'm able to hop on to GDM and my LHS monitor is
active. When the screens shut off after inactivity and wake again, I'm able
to get a signal.
Here's the adapter from Club 3D:
https://www.amazon.com/Club-3D-DisplayPort-Video-Adapter/dp/B085YBR936
Do *not* buy one from Foinnex. It advertises as being 4k@60Hz capable but
is only 4k@30Hz capable. The packaging denotes that but the product page
implies otherwise.
