Wallpaper: specific image file for different monitors / monitor configurations

[MS-User]

Hi *,

I am trying to use my Surface Pro3 in different configurations: a) Surface Screen only (Mon 1), b) Surface Screen (Mon 1) and external Monitor (Mon 2) and c) external Monitor only (Mon 1). As resolutions and aspect ratios are pretty different, I would like to asign a specific wallpaper file to a specific Monitor and/or resolution, i.e. going beyond the Monitor 1 vs. Monitor 2 assignment available in Windows 8.1 (and probably higher).

Any clue how to do this ?

Thanks and best regards, Sven
