I know HDMI can be a pain a lot of times and that this is most likely some sort of bios issue and not OpenBSD's fault, but does anyone know if there's a way to reinitialize the video back into life after the machine is already up and running? (the system is totally functional besides video, we can ssh in and do whatever).
We have a system with only HDMI and displayport video outputs. If the
system is booted with no HDMI cable attached, and then the cable is
attached after the system is up, video is completely nonfunctional until
the system is rebooted. (We don't have any displayport displays or
cables to test that side of things).
