Most people reading this will probably think that using your laptop as a secondary monitor is as simple as connecting your desktop to your laptop via an HDMI cable.

Don’t worry—this method is still very simple to complete. In this article, we’ll explore a number of ways to use your laptop as a second monitor and the benefits of doing so.

The first method requires the use of the built-in Windows feature Miracast. We’re going to use Miracast to turn your laptop into a secondary monitor.
- To set up your laptop as a second screen for your desktop computer, open up the Start menu and go into “Settings” (the gear icon).
- Inside Settings, find and select “System” (the icon of a mouse).

Miracast Connectivity Issues
It has been noted that some people have struggled to use the Miracast method, as it requires both the laptop and projector to support Intel HD graphics.
Some people with dedicated graphics cards have not been able to use this feature because of this limitation. Moreover, your desktop computer will require a wireless connection to the laptop.
I know many gaming computers use an ethernet cable to reduce latency issues. In this case, you’ll need to purchase a wireless network card or some form of wireless adapter.
