How to use an Android tablet as an external monitor?

An external monitor can increase comfort while working on laptops. Do you know you can use your android tablet as an external monitor? If not, this article is for you.

Not only the android tablet but also your android smartphone can be used as a small external monitor for your windows laptops.

You may ask why I need to use a tablet as an external monitor? Sometimes using an extra monitor makes your work more manageable rather than a single display. You can also spread out many applications to two screens.  But most of the time, buying an external monitor is not feasible. In that case, you can make use of your Table to act as an external monitor.

But you should keep in mind this is a temporary solution. If your tablet screen size is greater than 10 inches, then it will look good with your laptop and comfortable to use. You can also mirror/extend your laptop screen to your smartphone. Since it is a small screen, you may feel uncomfortable working with a smartphone as a second screen.

So the following steps will guide you to convert your tablet to an external monitor. You need a Windows 10 laptop with wireless display support, a wireless(Wi-Fi) network, and an android tablet with android version 4.2 or higher.
