How to Use Laptop as Monitor for PC

Do you have a laptop and a desktop computer? Do you want to use the laptop as a monitor for pc? In that case, this article is for you. Today I will tell you how to link your laptop with a desktop computer in a step-by-step guide.

Generally, a laptop has a smaller screen as compared to a desktop computer monitor. There is a reason why a laptop is called a portable computer.

You can easily carry it with you but that small screen makes it difficult for people who have to work on the bigger screens of their laptops all day long. In such cases, many people use their laptops as an external screen for their desktop computers.

How to use Laptop as Monitor for PC

Following are some of the ways to set up your laptop as an extended monitor for your desktop computer:

1. Using Miracast

Miracast is a wireless connection between your laptop and other devices. It lets you connect the two devices so that they can share data with each other without any cable or wire. You can see your desktop’s screen on your laptop via miracast.

In order to connect them, you will have to follow these steps:

Step 1. First of all, make sure that your desktop computer has miracast technology. If not, you will have to purchase it separately.

Step 2. Now connect your laptop with the Desktop PC via HDMI cable. There is an HDMI port on both of them so this step will be easy for you. Then turn on your desktop monitor and select the “PC” or “PC screen only” option from the display options.

Step 3. Now go to your laptop and check whether it is detecting a wireless display or not. In order to do so, open the action center from the charms bar of your laptop and click on “Project”. If it detects, you will see a list of all displays available for projection.

Step 4. If it does not detect, you can select “Add a wireless display”. Then connect your laptop with the miracast.

Step 5. Now on your desktop PC, right-click on the small icon of your desktop in the taskbar and select “Screen resolution”. In here, you will see all displays that are currently using the computer’s resources. It also shows the symbol of the laptop’s screen as “1”.

Step 6. Your laptop will now appear as an external monitor on your desktop PC and you can work on it just like you would do normally.

2. Using Third-Party Software

There is some third-party software that allows you to use your laptop as an external monitor for your desktop PC. Here is how you can do it:

1) First of all, open the start menu of your laptop and search for “Display”. You will see two options there; Extend and Duplicate.

2) Now click on “Duplicate”. It will show your desktop’s screen on the laptop’s monitor.

3) Now go to your desktop PC and right-click on the small icon of your desktop in the taskbar and select “Screen resolution”.

In here, you will see all displays that are currently using your PC’s resources. You will now see your laptop’s screen as “1” up there.

4) Now click on “Identity”. It will show the number of displays available for use.

5) Then just drag your desktop monitor to the left or right until it aligns with the number shown in your screen resolution option. So if your laptop has a screen of 1366 X 768, your desktop monitor should also be of the same resolution.

6) That’s it! Now you can use Laptop as a Monitor for PC using these steps.
