So in this guide we are talking about How to use Laptop as monitor.
Guide: How to use Laptop as monitor
If you want to expand the desktop display and use your laptop as a second or third monitor for your PC, we will show you how to do it in this guide. While this may seem like a simple process of just connecting a laptop to a desktop computer using an HDMI cable (or other video-in cable), it doesn’t really work. The HDMI port (or VGA or DVI or DisplayPort) on your notebook only works for display output and not as a video input for any other device. That is, if you want your laptop screen to be on a larger screen (TV, monitor, projector, etc.).
However, you cannot connect your notebook to a computer with a cable so that the notebook displays output from the computer. Using another monitor for work is a fantastic increase in productivity – no more split-screen action between Microsoft Word and Chrome. You no longer have to prioritize which window comes first. Multi-monitor settings also look great, and you can use another screen as a media display when not in use. If you do not have an additional monitor but an additional notebook, you can use the notebook as a kind of second screen.

You must first obtain the appropriate display cable for your notebook to connect it to the monitor. Your notebook can use an HDMI, DisplayPort, mini-DisplayPort cable or include a docking station. So find the right cable for your needs and connect it to the monitor.
Once done, go to Settings> Preferences> Display. You can also right-click on the desktop and click Display Settings, or use the Windows key + P to quickly switch between display modes. If your laptop has successfully connected to the monitor, you should see two or more numbered screens in the Select and Rearrange Displays section. If not, click Detect to have Windows search for another monitor.
If you are not sure which screen is which, click Identify and a number will appear to identify each screen. You can also rearrange the displays as you like. Be sure to click “Apply” when you’re done.
Scroll down to Multiple Displays and click on the drop-down menu. You can choose from a variety of options here, but one we’ll focus on is “Expand these ads.” Select it to expand your screen to more screens, and then check which screen you want to use as the main screen. And that’s all! You can now work on multiple screens on your Windows 10 laptop.
