Hi Kellie,
Thanks for your post. Please understand that Windows 11 does not support Dual Monitor lock screens. 1 monitor will have the lock screen (your MAIN) and all others will remain blank until you login to your compute. However, there are third party applications you can research to see if they work (but please bear in mind that these would not be supported by Microsoft, so please do it with extra care). Also, it is suggested to feedback to Microsoft develop team for this user voice. Kindly open the Edge and press Ctrl+Alt+I to open the Microsoft Feedback Hub and feedback the issue. Thanks very much for your understanding.
Best Regards,
Ian Xue
