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.
