This question already has an answer here:

I am already aware of how to set a custom logon background on Windows 7. I am also not trying to tile my plain wallpaper on my desktop. I am talking about the background on the logon/lock screen in Windows 7.

What happens is on machines that have multiple monitors with custom logon screens only the main monitor that has the logon screen will display a custom oem background - every other monitor is black and I think that is gross. The blacked out monitor screens still display the cursor but do not have a background on them.

Is there any tweak to make this happen or is this truly a limitation of Windows 7?

This question has been asked before and already has an answer. If those answers do not fully address your question, please ask a new question.

This behavior is normal. Only the primary screen shows the lock screen even in a default setup. – Ramhound May 1 '13 at 0:45
Right. I don't want to move the lock screen, just the wallpaper. Either to stretch or tile it somehow would be nice. – cyborgcommando0 May 1 '13 at 14:08
I know what you want and I have never seen it. My research indicates its not possible. My experience tells me that its because of the way Windows treats the monitor until you logged into a user account. – Ramhound May 1 '13 at 16:17

This is truly a limitation of Windows 7, introduced in Vista - it used to work in XP.

Even the DisplayFusion developers say :

The Windows 7 logon screen has no dual-monitor capability whatsoever, so we can't even develop a custom solution for it.

Your only option for screen lock (not logon) is a product such as the Clear lock freeware.
