OK. So now I get what @BeardyBrun was saying.
I did not get it previously when he wrote:
Of course!!! All we need is the ability to shift the render plane.
In my words that would be an ability to offset the total picture.
See my images below - similar to @BeardyBrun.
In trying to get the position right by adjusting xyz and heading, I overlooked the simple fact that once we have our VFR pilot view correct, all we need to do is shift the complete picture left without altering the pan/heading.
That should be a relatively simple modification because nothing about the SIM operation is being changed - just virtually shifting the projection sideways.
Below are my pictures that compliment the two shown by @BeardyBrun above.
Edit 20 May 2024.
To make it clearer and avoid confusion, I have added the two following images.
The first image is as MSFS displays the view of the cockpit - instrument panel is placed CENTRE of 55 inch TV screen… as we want in a dual seat cockpit.
The next image is how I want it to look… because I am sitting in the left seat.
The instrument panel has not moved but the background has. I made this image in Photoshop because it is not currently possible to get this view in MSFS2020.
20 June 2024 I have also swapped my old video with a new video toggling the above two images. See the external rendered field is toggling left and right with out any change in cockpit view. This represents the front TV. only. (Left and right TV monitors would show the relevant views as they currently do in multi-screen mode). See my previous post above with photos.
