So 2 of my monitors are hooked up via HDMI and the 3rd is an ACTIVE display port to HDMI adapter for a grand total of 3 monitors. I am currently running version 18.12.1 and when I boot my pc all my monitors stay grey, If I boot it with 2 monitors everything is fine, and once im at the login screen I can plug the 3rd back in and it works fine. Can anyone else help?
