How to use a Laptop as a Secondary Monitor?

Do you want to use your Laptop as a secondary monitor for your existing primary PC display for both work and gaming purposes? If you would like to extend your desktop's display and use your Laptop as a secondary monitor for your PC, then you will find this guide very useful.

If you are thinking of simply connecting your Laptop to your desktop via an HDMI cable, then you are wrong. The main reason is that the HDMI port or any other port such as VGA, DVI or DisplayPort works only for delivering output to large displays and will not work as a video input for another device. If you would like to display your Laptop's screen on a larger display or connect it to another external display, you can complete the task by simply connecting the additional display to your Laptop. The reality is that you cannot connect your Laptop to your PC via a cable to fetch the screen from your primary PC.

To use your Laptop's display to work as a monitor for another device, you should make use of the features available on Windows or install third-party software programs to establish connectivity. This article will examine the steps required to use a laptop as a secondary monitor to your main PC.

1.Working with Miracast on Windows Systems

The best way to use a laptop as a monitor is to work with the Miracast functionality included with Windows devices. The first step is to click on the Start menu and navigate to Settings. You can also select the search box on the Taskbar and type Settings. You should do this step on the Laptop you wish to use as a secondary display. Select System option and click on the "projecting to this PC" option in the left side menu. You should make sure to modify the first drop-down menu to Available. You can go through the other settings and configure them accordingly. It would help if you went back to the main PC you would like to set up as your Laptop secondary display.

Suppose the system throws a Red error message that reads, "Projecting to this PC. We are still trying to determine the feature capabilities". In that case, you should navigate to the Device Manager and uninstall/reinstall the Microsoft Wi-Fi Direct Virtual Adapter to resolve the error message.

It would help if you accepted the connection after navigating back to your Laptop. Finally, right-click on your desktop and select Display Settings on the main PC. You should make sure to choose Extend desktop to this display option located under Display | Multiple displays. The final step is to rearrange your desktop and laptop displays appropriately by dragging and dropping the display icons at the top of the Display Settings screen.

If Miracast is causing compatibility problems, you should try to use third-party software applications like Space Desk. To work with Space Desk, you should download the Space Desk Driver program on your main PC and the Space Desk Viewer Program on the Laptop you wish to use an extended display for your central system. The users had reported that Space Desk simplifies the configuration process, and you can make use of your Laptop as a comprehensive display much quicker than Miracast.

After installing the relevant software tools, you should open SpaceDesk from the Laptop, and the software will scan for the network. Select your computer from the list and select the OK Connect button. Your Laptop will now work as a secondary monitor to your primary. You should choose the Full Screen option from the View menu.
