Multiscreen Blank is a free and open-source software for PC that was created by an indie developer named Alexey Blinnikov. This utility tool is for people who use multiple monitors for the PC and helps them manage them by providing an easy and convenient way of switching between screens.

Just like Dual Monitor Tools, Multiscreen Blank provides a set of features and functions that will be helpful to users with multiple monitor setups. This portable tool is unique in that it allows you to "black out" any of your screens, which will help you focus on one task, boosting your productivity.

How do I use Multiscreen Blank?

When you first open Multiscreen Blank, you will see a simple window showing all your active monitors. This tool got its name from its ability to let you "blank" one of your screens out, thereby helping you focus more on what you need to do. This feature can be enabled simply by double-clicking inside the box of the corresponding monitor that you want.

Alternatively, you can also right-click on a box to see other options, such as mirroring its content, blanking or revealing only certain parts of it, or dimming its brightness so you can still partially see and use it. Blanked screens have context menus that let you change their background color or adjust their size and position on your screen.

One nice feature is called Scraps, which can also be used to blank out parts of a screen, as well as show local files like your images. Despite its feature set, one missing function could be added, though. There is no support for hotkeys to be able to set custom keyboard shortcuts, which would have made using it a lot easier and more intuitive.

A handy tool to manage your multi-monitor setups

All in all, Multiscreen Blank is a great utility that you should check out if you use multiple monitors on your computer. It makes the whole process of managing them simpler and more intuitive. It's easy to use, has plenty of options, and it's completely free. Highly recommended.
