However, you cannot connect your laptop to your PC with a cable to get your laptop to display what your PC is outputting. That means that if you want to display your laptop’s screen on a larger display (TV, monitor, projector, etc.) or connect it to another display to extend your laptop’s display, you can do so by simply connecting the additional display to your laptop. The HDMI port (or VGA, or DVI, or DisplayPort) that comes on your laptop will only work for outputting its display and it will not work as a video input for another device. While it might seem like a simple process where all you have to do is connect your laptop to your desktop with an HDMI cable (or other video input cable), the reality is that it doesn’t work like that. If you’re looking to extend your desktop’s display and use your laptop as a second or third monitor for your PC, in this guide, we’re going to show you how to do so. Want to use your laptop as a monitor? Need help setting it up? This guide will show you how to use your laptop as a monitor.
