chriz74 Posted July 24, 2019 Share Posted July 24, 2019 in an Asus laptop with a DP internal monitor, if the external is plugged in at boot the internal stays black, it's not recognized at all in the framebuffer. If boot without HDMI and then plug the external then both monitors work. Latest whatevergreen and lilu are being used. devices - properties are from rehabman plist.

Man, i solved this with a insane solution. Plug the external monitor, login, block the screen (Ctrl + Command + Q), let the monitors turn off and try to unblock. Weird solution but worked :D Link to comment https://www.insanelymac.com/forum/topic/339659-uhd-620-internal-screen-doesnt-turn-on-if-hdmi-screen-is-plugged-at-start/#findComment-2708125 Share on other sites More sharing options...
