And now, on the boot first stage everything goes to DP monitor until system reaches boot point when graphics mode switches. At this point, DP monitor turns off and HDMI moditor displays login screen. I am able to login but cannot turn on DP monitor. "Detect displays" does not detects DP display either. But if I unplug power from the working HDMI display, DP monitor becomes active and working. If I turn HDMI monitor back on, they both works just fine then. Please help! How to make them both working at boot and after again? Ty!

rlp Posted September 22, 2019 Share Posted September 22, 2019 I'd suggest to use HackinTool to check out your display ports are detected with the correct type. Otherwise you can generate a patch with the same tool to include in config.plist. There is a nice guide on other site.
