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 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?
