How to Use Laptop as Monitor on Window & Mac OS?

Use Laptop as Monitor or secondary screen is what this guide is all about. One of the best things about laptops is that they’re portable so that you can work anywhere you want. In the absence of alternative displays, people commonly miss the fact that laptops may function as monitors.

This is a simple method to improve your productivity. If you have multiple monitors, you can easily extend your Laptop’s display to span numerous screens. 

Thanks to the endless scrolling ability, you can see many web pages or cross-reference a document without moving between loads of tabs.

To put it another way, rather than just mirroring your Laptop’s screen on the monitor, you can show distinct applications and content on both screens by extending it.

Use Laptop as a Monitor or serve as another monitor is a valid alternative. Your Laptop merely displays the display and isn’t built to output another device’s display, like your TV.

How Do I Use Laptop as Monitor?

Laptops can serve as secondary screens for computers in any capacity, be it business, gaming, or schooling. 

You must have a firm awareness of your connection options, the operating system, and minor tweaks to your screen to correctly configure your Laptop as a monitor. 

It is regarded as one of the lesser-known Windows 10 features, although it is also believed to be moderately priced.

If you’re ready to use the equipment you currently have to create a better workflow and reduce the expense of buying a second monitor, this is for you. 

Here are the steps you need to follow to have tremendous success when setting up a laptop monitor as a secondary screen in your home or business.

How to Use Your Laptop as a Second Monitor?

Only a minority of buyers first consider a laptop as a second display when they purchase one. However, it is a pleasant thing to know that you have the choice available. 

Use Laptop as Monitor

If a laptop’s hardware and software are still working, you can use it as a monitor. Putting your slow Laptop on a shelf where it will collect dust or recycle it is no longer essential.

Use Laptop as Monitor allows you to enhance your workflow in numerous ways. This is what you can utilize the most:

  • side-by-side comparison
  • focusing on the study on one monitor while the other is used to create
  • Keep an unadorned screen dedicated to chat or messaging tools like Slack for extended periods.
  • Use a single display for setting up alerts and real-time notifications.
  • You can use one screen to watch the big game and do your job on the other screen.
  • Listen to your favourite YouTube gamer while playing the game and recording all your gameplay with an app like gameplay recording.

When switching between multiple programs, applications, or browser windows, having a second or third monitor can be beneficial. Once you begin utilizing it, you’ll think of all sorts of different ways to use it.

Bear in mind that the laptop display serves as a monitor, so don’t require all of the Laptop’s components to be functional to use it as an additional monitor. 

A functional display makes it an excellent addition for the busy gamer or business professional, even if you don’t have all the available capabilities.

What supplies do I need?

Remember that the following instructions only apply to laptops and desktops running Windows. Using your Apple laptop as an external monitor requires precise requirements, mainly if you use macOS.

You will need the following items:

  • Your primary computer for work will be a second screen for which you intend to utilize a laptop.
  • Microsoft Windows 10, which has recently been upgraded to the latest and greatest version, is now installed on both computers.

If you connect your laptop to a wireless display, Microsoft 10’s built-in Miracast technology will make it simple for you. 

No wires, connectors, or wireless dongles are required, as long as both computers are running the most recent version of the operating system.

A secondary cable or chord will not be needed to connect the primary computer to the Laptop, and any cables or cords that are marketed as doing this will not function. 

Almost always, the video connectors on laptops are exclusively for output and do not allow information from an outside source to be input to the Laptop. You should require the following:

There won’t be much preparation required. Ensure the primary computer is available, and have the Laptop you plan to use as a second screen ready. 

Both devices must have the newest version of Microsoft Windows 10 or higher installed. If you are an administrator, you may additionally need to be logged in.

Read on to Find Out How to Use Your Laptop as a Monitor

If your software is up to current and your devices are both turned on and discoverable, it only takes a minute to set up. These two easy steps will get you started:

Do you have a laptop that can be used as a monitor? Windows 10 comes ready to enable this functionality out of the box. There’s no additional equipment or effort required. Let’s choose between two options:

  1. Both machines must be running Windows 10
  2. Microsoft Windows 10 is the primary device, but the computer you want to utilize as a monitor is not (and is a Mac, Linux, or something else)

For Mac users, the content below doesn’t help scroll to the bottom.

#1) How to Use Laptop as Monitor Windows 10

1: To get the screen to show, you have to turn on the computer you want to screen.

  • You must right-click on your home screen (not in a browser or other application) and pick “Properties” on the contextual menu that appears.
  • Choose “System”
  • To project the image to this PC, make sure you select “Projecting to This PC.”
  • No matter which choice you choose, make sure it works for you.
  • ‘Windows 10 PCs and phones are allowed to project to this PC, as long as you agree it’s OK.’
  • Invite to this PC and offer to project: “First time only.”

2: Connecting your primary device (Desktop & Laptop)

  • On your device, hit the Windows key and the “P” key.
  • choose whether you prefer your screen to be viewed in one of two ways
  • Use your Laptop as a second monitor (like in the screen to the right). If you want both monitors to display the identical thing, you can select the Duplicate option.
  • It is essential to locate your Laptop’s device name so you can connect.
  • OK, to start utilizing both screens.
  • Excellent, there you have it.

#2) How to Use a Laptop as a Second Monitor for Mac Devices

To find out whether you’ll need an adapter to connect a second display to your MacBook, first check the ports on your device to see whether you have an adaptor required. 

It would help if you now had connected your cable to your monitor. Continue to the following step.

Launch the ‘System Preferences application, then go to ‘Displays’ in the ‘System Preferences’ menu and pick the ‘Arrangement’ option. 

The Mirror Display box must be deselected before dragging the displays to their intended locations. To choose the screen you want to use as your primary display, drag the menu bar to the screen.


Other Ways to Use Laptop as a Monitor

  • You have several ways to connect to your monitor’s extended display.
  • You should use the Duplicate feature to display the same stuff as your primary monitor if you want the laptop screen.
  • The second screen Only means only displaying the laptop screen, not the original monitor.

Advantages of following these guidelines

While using a laptop in conjunction with a dual monitor configuration will do well in several situations, it won’t be best for every occasion. 

Gamers will benefit from using a second screen for real-time discussion or guide docs.

However, for online or graphics-heavy games, you should have in mind that it is not optimal. Because the second screen may have delays when trying to transfer data, project only your gaming graphics to the primary monitor.

Microsoft Windows 7 and 8

The Extend function may still be able to display on a laptop even if you have an earlier version of Windows. With the purchase of a Microsoft Wireless Display Adapter, it is also feasible to use any modern monitor or TV as a secondary screen. 

This allows you to connect your original desktop or gadget to your computer through USB and HDMI. Projecting to a second screen is unnecessary if you use this route.

Tools for collaborating

Additional multi-tasking functionality, and one more thing: Also, when you’re connecting from the main desktop to the Laptop, choose “Allow Input” to enable input from both peripherals. 

To provide permission to use the second Laptop for touchscreen, pen, keyboard, and more, click the box. Collaboration, programming tasks, and design work can all be accomplished by having two people using the same device.

More productivity in minutes

Anyone who has ever questioned How to Use Laptop as Monitor should successfully implement these simple instructions. Repurposing old laptops into monitors is an excellent method to keep old devices out of landfills. 

With more and more laptop computers delivering higher-resolution displays, larger screens, and more vivid visuals, incorporating them into your workflow makes sense.


FAQs ― How to Use Laptop as a Monitor

  1. Can you use a laptop as a monitor with HDMI?

    A computer's HDMI (or VGA, DVI, or DisplayPort) port only functions as output and will not accept input from another device. 

    While you can link your Laptop to your PC with a cable to display your PC's output, you cannot connect your Laptop to your PC to output what it is showing on your screen.

  2. Can you use a laptop as a monitor?

    You certainly can. To connect your laptop to a monitor, you first need to purchase a display cable that is compatible with your Laptop. 

    Depending on whether your Laptop came with an HDMI cable, a DisplayPort cable, a mini-DisplayPort cable, or a docking station, find the correct cable and connect it to your monitor.

  3. How do I make my laptop HDMI input?

    There is no way to convert an HDMI output to an HDMI input. We're able to connect our HDMI devices using adapters to get HDMI input from anything like an external device and project it on another device, such as via USB ports or other connections.

  4. How can I use my laptop as a monitor for Raspberry Pi using HDMI?

    Plug your micro USB cord into the Pi, and it will provide electricity. Make sure your raspberry pi is connected to your Laptop by way of an ethernet wire. Make the keyboard and mouse physically link to it. 

    Now, connect the HDMI display to the display's HDMI port (the HDMI is only required for running the pi for the first time).

  5. Can I use my laptop as a monitor for PS5?

    But it's designed to be an output, so if you want to connect it to anything like a TV, an HDMI port is provided. Do not use this monitor as your PS5 display.

  6. Can I connect 2 laptops with HDMI?

    You need two HDMI ports (one for output and one for input) on the Laptop to complete this. In addition to the two HDMI connections, Alienware M17x and M18x versions come with a Mini DisplayPort. 

    A “one for input and one for output” arrangement. If you choose to have a second external laptop monitor, you can use an HDMI splitter.
