Older Laptop models used to have DVI and VGA cables to use as external monitors. But, newer models no longer use these and instead focus on using HDMI. So, you might wonder how to use a laptop as a monitor with HDMI.

Using an HDMI connection is a terrific alternative if you want to use your laptop as the primary screen for your computer. However, your Laptop and PC need an HDMI connector and HDMI capture card to do this, as HDMI can only take input.

It is an excellent choice to use a Laptop as an external display if your regular monitor has been broken or you don’t presently have one. Read the instructions below to learn how to utilize your Laptop as an additional display.

How to use a laptop as a monitor with HDMI?

As I mentioned earlier, I suggest you use an HDMI connector for connecting your Laptop as a monitor. Laptops cannot be used directly for HDMI input. Hence you will need to buy an additional HDMI capture Card. Follow the steps below to know how to connect your laptop as a primary monitor for your PC.

Step 1: Plugging HDMI cable into HDMI capture Card

Connecting your HDMI cable to your Laptop and PC and HDMI capture card is the first step. HDMI cables should have one end plugged into the GPU’s HDMI port and the other into the IN port of the HDMI capture card. Take a second HDMI cable, insert it into the capture card’s HDMI OUT connector, then attach the other end to the laptop’s HDMI port.

Step 2: Power on

You must now attach this external HDMI card to your computer. Simply connect a USB cord from the capture card to the PC. When everything is connected, you must switch on your computer and make sure your laptop is powered on too.


Step 3: Configuring Windows

Lift the lid, then turn on your laptop. You will be asked to select Detect display. To access the Display Settings screen, choose the prompt. Select Extended Display, and then make your external monitor the main or primary display.

Thus you have successfully selected your laptop screen as your primary display for the PC.

After selecting the appropriate cable, connect the HDMI cables to your HDMI capture card and then to your laptop that you wish to use as a Display, and take another cable to connect the capture card to your Mac.

Now simply turn on your laptop and your Mac, you should now see your Mac running on your laptop, and it should work as your primary monitor.

Step 4: Accept Connection Request

Choose the “Action Center” icon from the screen’s bottom right corner on your desktop computer. After that, click “Connect” and wait for your Laptop to show up on the screen. Now choose it when you see it appear on your screen.

Click the option when you reach “Advanced Display settings” by scrolling down. You have a number of options from here. Now you will be able to select your laptop display as your primary display or as a second display.
