multi monitor different res wallpaper problem

[elexi0s]

so when you have 2 monitors one with a higher resolution one with a lower, if the main monitor is the lower resolution one then if you apply a background to it then even if the resolution of the image is big enough to fill both monitors it applies the shrunk down wallpaper applied to the lower resolution monitor (to fit in the lower res the monitor) to the higher res monitor leaving a black border instead of the full resolution image which could fill it.

I've looked online but only found jumbled and confusing answers.

any helps appreciated <3

You might wanna take a look at purchasing Wallpaper Engine or Display Fusion

At work I use Ultramon with a 1440p monitor and a 4K TV and it has options to shrink or stretch the wallpaper to fit any connected display.

As above, Windows has just begun really supporting multiple monitors. Actual Multiple Monitors, UltraMon, DisplayFusion are multi-monitor software. Wallpaper Engine is purely for wallpaper handling. All should be able to handle your monitors as two different profiles, and so apply different settings if needed. AFAIK Windows settings freak out with two different resolution monitors.
