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.
