I am using one displayport 4k monitor, and one hdmi 1080p monitor. They keep waking each other up. When I used an adapter to make the 1080p monitor connect via a displayport > hdmi adapter, they both just output black when trying to sleep and cannot be woken up. They are still outputting black, they did not go to sleep.
