I think the next step is to determine if the mobo does in fact support two monitors via the integrated GPU.
I hightly doubt it would not. I have multiple Asus motherboards using IGPs from Intel or AMD, each with 4 video outputs. I also have one from Asrock and one from Gigabyte. The older ones all support two at once. The newer ones, which are now at least 3 years old, support 3 at once. This is from one of the newer, using a lowly Pentium CPU:

I have not yet completed investigating if the mobo supports two monitor but I tend to think it does. If I connect the second monitor after the OS has booted the second monitor works fine, except for the fact that the desktop is removed from the first monitor and the screens are duplicated. It the duplication is turned off then the desktop remains on the second monitor and the first one is available to the right or left.
This seems to be a software problem and not that the mobo cannot support two monitors.
to finally get the kernel driver loaded and the No Mans Sky game working one one monitor, I was/am loath to make changes with my poor knowledge state.
I don't even know what kernel driver is now loaded but it is working with the latest game Satisfactory. However, No Mans Sky no longer works (black screen).
I have posted an issue in respect of the dual monitor problem:
I was waiting until Ubuntu 21.04 LTS comes out to see if the issues are corrected. However, if you were able to and have the time to lead me through changes/tests, I would be grateful as you have the knowledge I lack. But, I would understand if you decide I should wait.
I am also waiting for GPU prices to fall to a reasonable level.
PS. I played my first game around the time covid forced us to be recluses for months on end, having never played computer games in the past.

cat /var/log/Xorg.0.log | pastebinit (if /var/log/Xorg.0.log exists) or (if ~/.local/share/xorg/Xorg.0.log exists) cat ~/.local/share/xorg/Xorg.0.log | pastebinit would show us which display driver is in use (intel DDX vs modesetting DIX), and possibly a reason why the game black screens.

There never will be any 21.04 LTS. Current (minor) LTS is 20.04.3. Next (major) LTS will be 22.04. Major LTS is released at 24 month intervals.
Those questions I asked in comment 12 are things to try, tests. Xorg.0.log will report whether you are using the DDX or the DIX. This primer gives an overview of the subject of display drivers. Both that may apply to your GT1 UHD Graphics 750 depend on the very same kernel device driver (module).
You can put an executable xrandr script in /etc/X11/Xsession.d/ in the form xrandr --output <outputname> --primary to designate the correct display to be the primary. The correct <outputname> depends on whether you're using the DDX or DIX driver, and is also reported in the Xorg.0.log.
To test whether video=HDMI-1:D helps, strike the E key at the Grub menu and type it in before proceeding to boot. It doesn't persist this way, meaning it only works for the current boot. This would only work if using the modesetting DIX. If using the intel DDX, then it needs to be video=HDMI1:D.

I used video=HDMI-1:D and grub continued but should I have had the second monitor connected?
Edit:
I tried with the second monitor connected and grub hung as it now usually does with both connected.
What exactly does "grub hung" mean? Was that using video=HDMI-1:D?
Yes that was using video=HDMI-1:D
By 'hung' I mean that after choosing ubuntu from the displayed list the system stops and goes no further. The only way to continue is to turn off the second monitor, unplug the HDMI cable and shut down the PC. Then reboot with just one monitor connected.
