Wondering if you can use a laptop as a monitor? It's entirely possible with the right setup and cables. Achieving a dual monitor setup with a laptop not only boosts productivity but also enhances your multitasking capabilities. Additionally, knowing the types of monitor cables available can help you select the best option for your needs. This guide will delve into how to use your laptop as a secondary display and discuss the various cables to connect laptop and monitor.

Using Your Laptop as a Monitor

Adaptability is essential in the modern workplace. When you do not have the room or money for a new screen but still want to get the most out of your laptop, using it as a monitor is a smart hack that will increase its usefulness. A number of OSes provide this capability through built-in features, such as "Project to this PC" in Windows 10 or "Target Display Mode" in macOS. To set up your laptop to function as an additional display or a copy of your main display, first, make sure your main and secondary screens are linked through a network or the right cable. Then, tweak the settings to your liking.
