Secondary Monitor showing black on lock screen?

[DigitalHD]

I want to be able to use my second monitor to display a 3840*1080 resolution wallpaper on my lock screen but is only showing half (on my primary monitor) of the image. Fairly new to PC building and such so have not tried much apart from looking through settings. Thanks

I don't think that Windows really shows much on a lock screen for a second monitor setup, not too sure though

If you have a dedicated Graphics card such as a Nvidia GPU, the drivers will allow you to 'Span Displays with surround' which will allow you to have a dual screen lock screen but may change other things when using full-screen mode.
To find this setting, right click on your desktop and see if Nvidia or AMD Radeon Control Panels are on the list. From there click Configure Surround and follow the on-screen options.
If the control panel for your Graphics card isn't there, then you may not have the appropriate hardware to do this.
