How To Use A Laptop As A Second Monitor With HDMI

If you have an extra laptop lying around and want to use it as a second monitor, there’s good news: it’s easy to do. All you need is an HDMI cable. Here’s how to set it up.

First, find an HDMI cable. You can get one at any electronics store, or even online. Once you have the cable, plug one end into your laptop and the other into your main monitor.

Next, open up your display settings on your main monitor. This is usually done by right-clicking on the desktop and selecting “Display Settings” from the drop-down menu. Once you’re in the display settings, find the section that says “Multiple Displays” or “Extend Desktop.”

Click the drop-down menu next to “Multiple Displays” and select “Extend Desktop to this display.” This will cause your main monitor to treat your laptop as an extension of itself. You can now move your mouse between the two screens, and even drag windows back and forth.

If you want to change the resolution of your laptop’s screen, you can do so by going into the display settings on your laptop. Just remember that the higher the resolution, the smaller everything will appear on your screen. Conversely, the lower the resolution, the bigger everything will appear.

You can also change the orientation of your laptop’s screen by going into the display settings. This can be handy if you want to have your laptop’s screen be vertical instead of horizontal. Just remember to change it back when you’re done, as it can be a bit disorienting to use your laptop with the screen upside down!

And that’s all there is to it! Using an extra laptop as a second monitor is a great way to increase your productivity, or just have some extra screen real estate to play around with. Just remember to plug it in with an HDMI cable, and you’re good to go.
