Triple screen issue when ingame resolution differs from desktop resolution

Hi there,

i got some issues regarding different rendering resolutions, maybe somebody can help

I'm running AMS2 with triple 4k Screens. When I set the ingame resolution matching my desktop resolution (for example desktop 11520x2160 - ingame 11520x2160 or desktop 7680x1440 - ingame 7680x1440) everything works fine.

But whenever I set my ingames resolution lower than desktop resolution the whole image seems to be moved to the right side, meaning that for example the dashboard of the car I'm driving doesn't appear on my center screen, but on my right screen that is completely weired. Ingame menu etc. are fine, the image moves to the right side when the race starts. I attached an image, showing this issue.

Although the easiest solution seems to set the desktop and ingame resolution equally, I would like to set my desktop resolution to native (11520x2160) and my ingame resolution lower (f.e. 7680x1440, night and/or rain are too demanding in triple 4k), because for other purposes I need the desktop resolution to be set higher - switching the desktop resolutions is quite annoying (nvidia surround )

I have no idea why choosing a lower resolution ingame than desktop's resolution causes this strange image movement to the right side
