My video capture card supports HDMI video signal input, USB/TYPE-c 2-in-1 output.
Connect the video capture card to the computer you want to capture BIOS with HDMI, and plug the USB into the recording computer.
Install the OBS Studio video recording software on the computer you are recording. OBS can be configured in a variety of usage scenarios, and you can quickly switch between settings in advance, create a new scene, and add a video capture device source.
Because I have already added the device before, the device will be displayed in the Add existing option, if it is a new device, select New, and customize the name.
Next, select the video capture card in the device options, and it is recommended to check "Disable when it is not displayed", otherwise the capture card will be used in one scene, and then the new video capture card will not be used in other scenarios.
Back to the main interface, you can click Start Recording to record the screen of your operation.
It is also possible to pause during recording
Right-click on the recording preview window to select many useful functions, such as full-screen preview, screenshot and other functions.
If you need to record the operation interface in scenarios such as recording videos, online classes, and live broadcasts, then this kind of video capture card is definitely worth investing in.
