Anything else we should know?
My computer is set up in this config:

I have two video cards. GPU 1 goes to center screen via display port. It is also connected to a Valve Index (behavior still happens with Index unplugged)
GPU 2 goes to screens 2,3, and 4. 4 uses a DisplayPort to HDMI adaptor, but is always on (drawing tablet)
When I power off screens 1,2 and 3, Windows sees the new layout as the following:

The main display screen is not being seen.
When I turn everything back on, it returns to the first image.
When I turn on OBS Studio, the display capture will have done one of the following: Defaulted to capture screen 2, 3, or 4. It is not returning the capture to the center primary screen. OBS was never opened when the monitors were turned off.

Research direction
Start by reviewing the linked OBS Studio log and reproducing the issue on Windows 10 with the described multi-monitor DisplayPort setup. Check whether restarting OBS after the monitors are powered off and on selects a different display. Done means the configured center display remains selected after this power cycle.
