Why Use a Windows Laptop as a Monitor?
Ever stared at your crowded desktop screen thinking, “Man, I could really use more space”? Yeah, me too. Between 15 open tabs, Zoom calls, and music playing in the background, my screen felt like Times Square at rush hour. That’s when I discovered you could use a laptop as a second monitor in Windows 10, and let me tell you—it was like adding an extra room to a tiny apartment.
Whether you’re working from home, gaming on the side, or giving a killer PowerPoint presentation, a second screen can be a total game-changer. And the best part? If you already own a Windows laptop, you’re halfway there. You’re probably wondering, “Can I use my Windows laptop as a second monitor?” Absolutely, yes. And I’m going to show you how in plain, simple steps.
Getting Started: What You Need Before You Begin
Before we dive into cables and clicks, let’s make sure you’ve got the right gear. This isn’t one of those setups that require a NASA-level toolkit. You just need:
- Two Windows computers—both running Windows 10 or later
- A stable Wi-Fi network (both devices should be connected to the same one)
- Your systems updated to the latest version (no one likes surprise bugs!)
- Optional but handy: software like SpaceDesk if things get tricky
If you’re setting up a Windows wireless display, make sure your laptop has the “Wireless Display” feature installed. Think of it like prepping your ingredients before you bake—everything’s smoother when it’s all in place.
Step-by-Step: How to Use Windows Laptop as Monitor
Alright, roll up those sleeves—it’s easier than you think.
Step 1: Enable Projection on the Laptop
This is your secondary screen—your sidekick. Go to the laptop you’ll be using as a monitor and open Settings > System > Projecting to this PC.
If the options are grayed out, don’t panic. Just click Optional Features under Apps and install “Wireless Display.” It takes a few minutes, so maybe grab a snack while it downloads.
Once it’s installed, set the options like this:
- Available everywhere
- Ask every time a connection is requested
- Skip the PIN unless you want extra security
Voilà! Your laptop is now ready to accept projection. It’s basically raising its hand, saying, “Pick me, pick me!”
Step 2: Connect Your Main PC
On your desktop or main laptop, press Windows + P. A little panel slides in from the side—like magic. Choose “Connect to a wireless display,” and a list of devices will pop up. Select your laptop from the list.
Your laptop will show a notification asking for permission. Click Allow once (or always if you’re cool with it), and bam! You’re connected.
Step 3: Extend or Mirror—Your Call
Once connected, go to Display Settings on your main PC. Scroll down to Multiple Displays and choose “Extend these displays” to make your laptop screen part of your desktop. If you just want the same screen duplicated (maybe for a slideshow), pick “Duplicate.”
Here’s where the magic happens. Now, you can extend display to laptop screen, drag windows over, multitask like a pro, and stop playing desktop Tetris with your browser tabs.
Troubleshooting & Common Issues
Of course, no setup guide is complete without a few bumps in the road. Here are some quick fixes:
- Laptop doesn’t show up in the list? Make sure both devices are on the same Wi-Fi and not on VPNs.
- Settings still grayed out? Recheck that “Wireless Display” is installed.
- Laggy display? That’s wireless for you. Try closing background apps or move closer to the router.
You can also try mirroring PC screen to laptop if extending gets glitchy. It’s less dynamic but still gets the job done in a pinch.
And yes, HDMI won’t work unless your laptop has an HDMI input—which most don’t. HDMI output and input are not the same thing. So, unless you’ve found a magical unicorn laptop, stick with the wireless method or third-party software.
