On previous versions of Windows, users who use more than one monitor were able to have their lock screen on each of the monitors that were connected to their PC. However, users who have Windows 10 on their PC, do not have access to this same feature.
The dual monitors lock screen feature does not work on Windows 10, as only one (the main monitor) will display the lock screen and the other monitor(s) will display a black screen.
According to Microsoft’s customer support, the dual monitors lock screen feature is not available on Windows 10 due to the OS being on an entirely new architecture. Reportedly, the team in Microsoft is still working on a solution to fix the issue.
How to fix black screen issues on Windows 10 dual monitors
Install Nvidia Surround
For now, there are some workarounds that can resolve the problem to a degree. For instance, some users use the program called Nvidia Surround, which allows them to treat their multiple monitors like a single monitor. While this Nvidia feature is designed for gaming on multiple monitors, it can also be utilized to make your dual monitors lock screen more attractive.
Install multi-monitor tweaking apps
Another method users have used to fix the black screen issue is by using third party multi-monitor tweaking programs. Apparently, programs like these can allow you to configure your settings to create dual monitors lock screens. It is important to note, that third party programs are not provided or supported by Microsoft. Therefore, it is never safe to completely trust a third party program that tweaks your Windows settings.
Download them at your own risk as some of these programs may inject malicious code into your PC.
Nevertheless, using third party programs seems to be the only way to solve the the issue at the moment. It is rumored that the pro version of Display Fusion allows users to workaround the issue. The program also offers many other features that allows you to tweak other parts of your Windows 10 OS, like Windows management, monitor controls, remote controls, power functions, and more. It is probably the closest thing you will find to a dual monitors lock screen solution on Windows 10.
