Describe your issue:
Steps to reproduce:
1. Connect the monitors as in the title (or, connect the 4K and 1440p monitors as listed and the 1200p monitor to HDMI)
2. Set wallpaper background to shuffle in Windows Settings
2 of the monitors (always adjacent to each other) have the same background.
What should happen:
All 3 monitors should have different backgrounds.
I suggest you also post a query @ http://www.tenforums.com/ for what seems to be an OS function issue.
Thanks. Already posted this in r/Windows10 and also at Microsoft Answers. Feedback Hub next, I guess.
