Playing a Game and Streaming:
Even if you use your computer to play games, you would still want to use your laptop as an external screen.
This is due to the reason that even if you want to use your PC for playing a game, having an external screen can be great for using Discord, Spotify, OBS for streaming, stream chat, and much more next to your games.

- Second, you will need to ensure that both your systems have the latest version of Windows 10 installed on them.
- Last, you will need to ensure that you have a high speed WiFi in your home.
As for the things that you won’t need, you will be glad to know that an HDMI cable is not required for this connectivity since it is done completely wirelessly. Even though there are various miracast display apps available everywhere, we will be using inbuilt features of Windows to connect your device like a second display.
How to use your Laptop as a Second Monitor?
If you are wondering about how to use my laptop as an external display, then you will be glad to know that it is quite easy to do. Windows 10 allows you to do the same within Windows 10 settings.
This is made possible thanks to the miracast display features offered by the latest version of Windows 10. Thus, if you opened this guide to know how to use my laptop like an external display, then simply follow the given instructions one by one:
1. Connect all Computers to the same WiFi
In order to use your laptop as a secondary display with another laptop or desktop, you need to ensure that all of them are connected to the same WiFi network.
To ensure the same, you first need to open Windows Settings on your PC.
- Once you are in the Settings menu, go to the Network & Internet menu on each device one by one. Here, simply connect to the same WiFi from the WiFi section present in the left hand side menu. Once this is done, you will be able to use your laptop as an external display with ease.
If you do not have a WiFi router at your home, then you can simply turn on the WiFi hotspot of your smartphone and connect each device to the same WiFi.
2. Choose the Right Settings to Use a Laptop as a Monitor
After you have connected each device to the same WiFi, you need to first set up your system and change its settings in a way that it can be used as an external display with either another laptop or a desktop for making a dual display desk setup with ease.
- To start, go to your laptop’s Windows settings via Windows search and open the System settings to open the Projecting to this PC settings from the left hand side panel.
- Now, you need to go through each drop down menu and select the right settings as given here:
Windows and Android Devices and Project to this PC when you say it’s OK: Available Everywhere
Ask to Project to this PC: Every Time
Require PIN for Pairing: Never
This PC can be Discovered only when Plugged In: Disable
3. Connect your Laptop or Desktop with your Secondary Laptop
Once you have gone through each of the drop down menu settings given above, you can move over to your primary device like a laptop or a desktop from which you want to stream video output as a source.
On the primary laptop or desktop system, open the Display Settings using the Windows search feature. Here you will find a table of contents regarding all the various display settings that you may want to change on your PC.
- Here, scroll down and select the Connect to a Wireless Display option to begin connecting your laptop’s display via miracast.
- You will then see a list of displays or system options that you can choose to connect as a miracast display.
- After selecting your desired system for a connection, you will need to accept the connection on your laptop that you are using as an external display. This same method will work in both cases whether you are using a laptop or a desktop for connecting a miracast display.
Things to Consider after Connecting a Laptop as a Monitor
Upon going through the guide given above, you must be using your Windows devices together as secondary display and primary system with ease. But if you are using the miracast tech for the first time, then there are certain things you should know.
In other words, to get the most out of your laptop’s display, you need to ensure that you are using it correctly. Even though this display feature for using a extend display mode is quite handy for compact desk setups, it still have some limitations that you can also find down here:
Change the Monitor Modes for your Laptop Monitor
One of the best things about using such miracast displays is that they act just like all other HDMI displays that you will find out there. Hence, you can change the monitor modes like PC only, duplicate, extend, and second screen only.
For the same, you press Windows Key + P on your keyboard which will offer you a list of different ways to extend your computer’s display. Out of all these, the “extend desktop to this display” is considered as one of the most versatile options.
Using a Laptop as a Monitor on Windows 7 and Windows 8
If you are using older Windows 7 or Windows 8 devices and want to use them along with your laptop’s display, then you will be glad to know that they also support the miracast tech.
To use this tech, you can simply follow similar instructions on such older operating systems or use the Windows search to find the same display settings.
Controlling a Computer via a Laptop being used as a Monitor
Apart from acting like a display, you can also use the keyboard and touchpad of your secondary laptop for controlling your desktop or laptop. To allow this, you need to simply select the “Allow Input” option while creating the connection for a miracast display.
Projecting to this PC over a Wired Connection
Those of you who are using a desktop most likely use an ethernet cable with it and do not have WiFi. Unfortunately, this means that you cannot project to your desktop without getting a WiFi adapter for your desktop to enable miracast projection.
Can you use a Mac Laptop as a Monitor?
In case you are using Apple based devices, then you won’t be able to use it with miracast. In other words, if you want to extend an Apple device as an external display, then you will need to use some third party app. Even if your Apple notebook comes with an HDMI port, it only supports output.
What’s the Difference between a Monitor and using a Laptop like one?
Even though a laptop’s display connected via software is great if you have a tight space on your desk, it is not viable for gaming. Because of the limited data transmission speeds of WiFi, such a display is only ideal for basic tasks and not gaming.
Projecting to this PC is not Available
To fix this issue, you can simply use the Search bar to look for “Add or Remove Programs” and go to the Optional Features section. Here, search for Wireless Display, right click on it, and add this software feature to your devices.
It will be automatically downloaded from the Microsoft website for using displays without needing a cable. If it is not available here, you can also manually download it from Microsoft’s site.
Using an older laptop or a secondary laptop that you have laying around as an external screen can be a great idea. This allows you to use your laptop screen for opening extra applications with ease on your PC.
