How to use a laptop as a monitor? The small size of the screen of old monitors while working or playing can be annoying for many users. Often access to just one monitor can not meet the widespread needs of users. On the other hand, the price of independent monitors is very high these days. Therefore, using laptop screens as a temporary replacement or as a tool for screen development can be a good choice.

Normally, in older versions of Windows, you could not use the laptop screen as a standalone device. Or at least the routine was not simply accessible these days. Fortunately, in Windows 10, this possibility is easily provided for users. And you can easily turn your laptop screen into a standalone monitor with just a few clicks.

To do this, you must first prepare a source laptop that supports the Miracast feature. Enter the settings of the Projecting section by searching for the phrase “Projecting to this PC”. From the first drop-down menu on the page, grant access to the laptop.

Note that if you do not have the option to change the settings, it means that your laptop or notebook will not support Miracast. In this case, the best alternative for you is to use third-party software.
Now you have to go to the destination computer. Enter the screen settings by pressing the Windows and P keys at the same time. From the drop-down menu, select Connect to a wireless display, and from the next screen, select your laptop from the available devices. Now you just have to wait a few minutes for the connection.

As mentioned, not all laptops support Miracast. As a result, you may not be able to use the first method. So to further enhance this experience, you can also use third-party tools such as free and available software.
These tools include Space Desk, Input Director, Sharemouse, and more. These tools will allow you to use your laptop or notebook as a standalone display in the simplest possible way.
