If you own two computers, you’ve probably thought about how advantageous it would be to connect them to each other via an HDMI connection at some point. It is quite unlikely that you will be able to connect your computers using just an HDMI connection due to the fact that certain laptops do not come equipped with an HDMI input port. On the other hand, there are a number of additional methods to link a laptop to an external display or to mirror the screen of one laptop onto another. You will learn how to mirror one laptop screen onto another using a video capture card, as well as how to set up an external monitor as a secondary display.
Spend your money on a capture card. Explore the many possibilities for capture cards that are available, and choose the capture card that seems to be the best fit for your purposes. For the sake of this solution, we advise use a USB capture card that also has an HDMI In connector.
- If you are going to be mirroring a programme that has to be seen in high resolution and have a high frame rate, then you need to invest in a capture card that is capable of meeting both of those requirements.
Download and install OBS on the additional laptop you have available. OBS, which stands for Open Broadcaster Software, is an application that was originally developed for live streaming and video recording; nevertheless, in this scenario, it is ideal for reflecting your screen. Download the programme onto the laptop that will serve as your mirror display, then launch the installer and follow the on-screen instructions to complete the setup.
Connect your capture card to the second laptop that you have. Through the use of the built-in USB port, connect your capture card to the laptop on which OBS has been installed.
- You may purchase an adaptor if your laptop does not come equipped with a USB port. This adapter from Apple will enable you to connect a USB device to a newer Macbook, for example, which only has Thunderbolt 3.0 ports available for connections.
You will need to use an HDMI cable to connect your main laptop to the capture card. After you have inserted one end of an HDMI cable into the laptop you want to mirror and the other end of the cable into the HDMI port on the capture card, you are ready to begin mirroring your screen.
- To reiterate, in the event that your laptop does not come equipped with an HDMI connector, you may purchase an adaptor. With the help of this adapter from Apple, you’ll be able to connect your laptop to an HDMI cable (as well as your charger and a standard USB device).
- When you initially attach the capture card to the secondary laptop, it will most likely show a message that says “Setting up a device.”
- Launch OBS and adjust its settings to work with the virtual camera. Open OBS on your other laptop, and after that, choose the option that says “I will only be utilising the virtual camera.” Click the Next button twice, then click the Apply Settings button.
- You should start the process of adding your capture card as an OBS source. In OBS, pick the Video Capture Device by first clicking the + symbol that is located on the bottom left of the screen in the “Sources” section. After that, in the textbox that’s labelled “Create new,” give your capture card a name, and then click the OK button.
- Make your capture card the input device by selecting it from the menu. In the Device dropdown menu, choose your capture card and click it. The name of the capture card need to be something along the lines of “Video Capture.”
Check your selection and adjust the size of the OBS window. When you have finished choosing the appropriate capture card, the screen of your main laptop should appear in OBS. After selecting OK, you will need to modify the dimensions of your OBS window in order to complete configuring your mirrored display.
- If your mirrored display is experiencing latency, click the Settings button located in the lower right corner of the OBS window. Next, pick a higher frame rate from the Video tab. Experiment with different settings until you find one that provides flawless mirroring while maintaining a framerate that your laptop can manage.
