This is monitor setup, how do i set up a fitting wallpaper?

[TheSahand]

I have a monitor on the left at 1200x1600 (since it's in portrait)
and the main monitor, at 1920x1200

they line up exactly along the top


how can I get a wallpaper that goes across nicely?




any you'd recommend that wouldn't exactly go across nicely but look good on two screens like this nonetheless?

Take a large photo, any photo and crop it. Take the full length for the screen on the left so it fills it. Them crop the rest of the photo proportionally to fit the horizontal screen.
