Montelli Posted October 21, 2023 Share Posted October 21, 2023 Greetings, about a year ago I upgraded my hackintosh from clover to opencore 0.8.7 to install Monterey 12.4 everything went fine. I would like to use a third display to extend my desk and I tried connecting it to the HDMI port on motherboard (integrated GPU UHD Graphics 630) but Monterey doesn't detect the device. On system information I read that active GPU is AMD Radeon RX 560 4 GB and in fact I have always used this with my two displays. Now how can I also activate the integrated GPU? Thank you in advance Link to comment https://www.insanelymac.com/forum/topic/357880-help-how-can-i-activate-integrated-hdmi-gpu/ Share on other sites More sharing options...

Montelli Posted October 22, 2023 Author Share Posted October 22, 2023 (edited) I noticed that iGPU multi monitor was disabled in the bios and now I have enabled it: but unfortunately the third display screen is all green, why?
