fixing graphical.target blank console monitor RHEL 8

specifically for RHEL-8.10 (or later I guess) where the old /etc/X11/org.conf is no longer used. - With a monitor connected off the server vga motherboard port, - and having one or more nvidia graphics cards installed, - When installing RHEL-8.10 from iso as Server with GUI the graphics at the monitor connected at the server vga port port works. You can get through the installation process until it says reboot and then after that the accept license agreement screen graphically even comes up and works. - But after that the graphical login screen when prompted to enter username is just a blank screen. - It was intermittent, doing a ctrl-alt-f2 would sometimes give you the completely text based multi-user.target style of display but after subsequent reboots that no longer works such that you either have to have systemctl set-default multi-user.target in effect or SSH into the system and do a systemctl isolate multi-user.target to get any kind of functionality on the console VGA monitor. - an lspci | grep -i vga responds with - 03:00.0 VGA compatible... Matrox Electronics G200ew3 - 3b:00.0 VGA compatible... Nvidia GA104GL RTXA4000 - *and on some servers I have a second listed nvidia GA104GL RTXA4000 shown* On a few servers I have, when they have 2 nvidia cards this problem is always present. But I have 2 servers having only 1 nvidia card installed each and one works with monitor off the vga port graphically in graphical.target but the other server does not - and I installed rhel-8.10 identically on both. What causes this, and how can graphics in RHEL 8 be fixed in this situation? What files do I go look for? **How do i instruct Linux to specifically output on 03:00.0 Matrox G200ew3 ?**
