HDMI monitor does not wake up in multi-monitor setup

Hi!

I have three monitors attached to my system:

  • Dell AW3418DW, attached via DisplayPort
  • Dell U2718Q, attached via DisplayPort
  • Dell U2718Q, attached via HDMI.

The HDMI-attached monitor does not wake up appropriately from boot, or from DPMS suspend. I have to power cycle the monitor to get it to wake up. This does not happen in Windows, which indicates that it’s likely a driver issue.

This was working fine on an EVGA 1080Ti card, but I recently upgraded to a Gigabyte 3090, and this started occurring.
