HDMI connected monitors not recognized
 

I had my MacBook Pro set up this morning on the dock with three external monitors. I have been running it this way for months. I relocated my computer to another room and hooked everything back up, but the monitors that are connected by HDMI are no longer working. The VGA monitor is working fine.

I have switched the cords to different monitors and each one will work if hooked to the VGA, but none work hooked to HDMI. When I go into Displays, only one external monitor is showing (the one hooked up by VGA). Does anyone have any advice?

Same problem
 

Following this. Same problem. It suddenly started today. My M1 goes to sleep and when it awakes, the monitors are not detected. I updated my DL software yesterday. The only way I can get the monitors detected is to restart my computer.
