Im trying to set two different images on 2 monitors, but it just shows the same image on both monitors.
Ive checked "use a different image for each monitor" and in the settings it's shown correctly, but the outcome is wrong.

(in screenshot you can see title of WP in left corner to be "left" on both monitors.)

any idea what to do?

I think Ive got it: I needed to enable taskbar on both monitors, then it worked.

Ive turned off taskbar on both monitors now, lets see how long itll stay correct
