In Mojave it's OK....I'm just using it....no problem... (Catalina still crazy)

I tried all, pikera too.... Very strange....I saw something in the logs about not sufficient energy to that port (DVI and HDMI same connector) right before "Login Screen"

Already with igfxonln=1...no change....

Hi....this is the problem.... 1-) Boot with HDMI connected: - After Apple logo, laptop display goes black / HDMI monitor as secondary display normal; 2-) Boot with HDMI disconnected: - Laptop display normal, then after Login screen I connect the HDMI display and get the two displays with image; ps: MacOS Catalina is installed... This is driving me crazy????....any help??? Lenovo Yoga 710-15ISK Intel HD520 Thank you! config.plist.zip
