Hello Everyone,
I would like to ask for some help with my dual GPU setup with two identical GeForce® GTX 1650 WINDFORCE OC 4G.
I want to use them to display some static websites in six (3+3) 4k capable (Samsung) TV.
So I’m not interested in optimal performance or anything, I just want the cards to work with the 6 HDMI output.)
My specs in detail:

Both VGA working flawlessly by themselves, from any of the PCI-E slot.
Both can recognize 3 HDMI connected TV (4k res) and a DP connected DELL (1920x1080) monitor.
I could even make a VNC connection and do some remote work!
The main problem:
There is no scenario where all of the connected displays (6 TV + 1 monitor) are recognized at the same time.
sudo -H nvidia-settings # only one of the GPU-s are in the list
For the sake of simplicity I took the whole PC and connected 2 FHD (LG) monitor
- instead of the 7 big screen - to test the multi GPU displaying. Sadly, without success.
I tried many distributions (Linux Mint 19.2, Manjaro 18.1.0, Ubuntu 19.04)
with different kernels (4.15, 4.19, 5.0) and desktop environments
(XFCE 4.12-, 4.14, Gnome 3.32, so lightdm and gdm were also tested).

Test results:
- With proprietary driver installed:
(by default: 430.26, from ppa:graphics-drivers/ppa repo: 435.21, 390.77)
the second monitor is fully blank.
I tried…
… to delete displays.xml:
mv ~/.config/xfce4/xfconf/xfce-perchannel-xml/displays.xml ~/.displays.xml.bak…to modify (the appropriate) xorg.conf (in /etc/X11/ or xorg.conf.d or mhwd.d):
Option "Xinerama" "1" Option "MultiGPU" "On" Option "BaseMosaic" "On"…to blacklist nouveau:
bash -c "echo blacklist nouveau > /etc/modprobe.d/blacklist-nvidia-nouveau.conf" bash -c "echo options nouveau modeset=0 >> /etc/modprobe.d/blacklist-nvidia-nouveau.conf" rm -f /boot/initrd* update-initramfs -c -k all update-grub - Without proprietary driver: same (empty second display). Interestingly with an auto-configured xorg.conf (X --configure provided me a basic config) it kinda' works: the second monitor has a desktop, but the resolution on both monitor are 640x480 and after opening the Display settings: it freezes. I could not even change to other virtual console to open another session or something. As for the resolution: the usual gtf; xrandr --newmode; xrandr --addmode commands dropped some errors, so I gave up.
After all this, I figured, why not try to merge
the Nvidia generated xorg.conf with the kinda’ working one, like:

It did not help.
Am I missing something? Should I use SLI for this kind of thing, or my xorg.conf is to blame?
Thanks in advance for any help.
