What You’ll Need

Before diving into the steps, let’s ensure you have all the required tools:

A laptop with an HDMI port or wireless display capability
An HDMI cable (if you plan to use a wired connection)
Software like SpaceDesk or Microsoft’s Wireless Display for wireless connections
A primary device like a desktop, gaming console, or another laptop
Reliable internet for wireless connections

Compatibility is key, so make sure both your laptop and the other device support the connection methods mentioned below.

1. Using Windows Built-in Wireless Display (for Windows devices)

If both your laptop and the other device are running Windows 10 or later, you can use the built-in wireless display feature.

Steps:

On the laptop to be used as a monitor:

- Select Connect to a wireless display and choose your laptop from the list.
