UPDATE: (SOLVED) 1. I did my best to analyze the iOreg informations regarding frambuffers, studying and practicing what is the effect on config file. 2. From the iOreg information, I corrected the framebuffers in my config file and from there after reboot, both screen displayed and with signal. Thank you and more power to this Website advocacy and mission. Thank you Jake Lo for the answers... from it, I decided to check the iOreg carefully. Your The Best!!! My family can use this computer now for looking work online, church work, school projects and more. THANK YOU TO ALL TEAM OF https://osxlatitude.com GOD BLESS YOU ALL. desmac IOREG_FINAL.zip

heysahilsingh, Hello! 1. Can you upload the EFI file for us to look at some settings. 2. What about your monitor and motherboart ports picture (DVI ports). Thank You.

GREETINGS! I am having a hard time making my setup to work with dual monitor (multiple display) with HDMI and DISPLAY PORT connection at the same time. Currently, HDMI is working and DP is working individually but when it comes to dual monitor/display no luck. I already spent lot of time looking for solutions but still the problem exist. I’ve done some trials like SMBIOS changing etc… Btw, since I have only HDMI ports in my two monitors, I used 1 display port-hdmi adapter for the other monitor. I am sure there is a solution to this, when booting the open core displayed in the 1 monitor and when it comes to log-in for the macOs it is diplayed in the other. leaving 1 is no signal or display. Is it possible for my setup to activate dual monitor/display? I really need it for my setup. WIFI Quantomn not working. (not really important) THANK YOU EVERYONE for possible help. It will save me time for me and my family.
