To clarify, are you looking to have the lock screen background keep changing while the machine is locked, or you want the desktop wallpaper to keep changing while it's locked so that you have a different desktop wallpaper the next time you log in?

Ok, unfortunately it's not possible to do, as the logon screen background won't refresh until the computer is unlocked, and then locked again

Sorry!

Currently you can only have it cycle with the wallpaper that's set on the primary monitor, by enabling the "Use the current Desktop Wallpaper image..." option.

However, we do have an open feature request for the ability to specify separate random image options for the Windows Logon Background. The current issue is that it throws a UAC prompt every time it changes, because the Window Logon Background settings and image are stored in protected areas of the OS. We're hoping to be able to use a service to change it in the future, so I'll be sure to post an update if/when we're able to implement that.

Thanks!

Thanks, we'll definitely check it out!

@AJStevens: Vote added. Unfortunately Windows disables the other monitors at the login screen, so it's not possible to show a background on the other monitors

We've just released a new DisplayFusion beta version and changing the Windows Logon Background will no longer throw a UAC prompt. Please let us know if you run into any trouble after updating.

Thanks!

No worries! We keep the feature request list internal, but rest assured, I've added your vote to it

Thanks!
