Hi there chemfox,

It sounds, if I understand correctly, like you have a couple displays attached to your iMac but they don't seem to be recognized or turn on when you turn the computer on. I would use the following article to help you troubleshoot those external monitors.

Get help with video issues on external displays connected to your Mac

If that is not the case then can you elaborate on what the issue you are seeing is?

Cheers!
