USBC input from second computer

Setting up video streaming for a church.
I have a main computer running windows 11 (with a I7-13 gen). I have another computer running windows 11, that supports 3 monitors (one being USBC) . This computer will be outputting two HDMI channels, 1 for the main user screen, the second to feed 3 displays for the auditorium, and one on the soundbooth desk with power points.
The main computer will be running obs studio. It has a usb C port.

Can I simply plug a USBC cable between the two computers, have the second computer mirror the second hdmi that feeds the displays, to the USBC output, such that it would be a video out, and then connect the other end of the USBC cable to the main computer USBC port, and use that as a video source feed for OBS so that I can capture the powerpoint slides and do picture in picture?

Hello scrungy: I run the live stream for our church, and we have the fairly common situation where the slides are on a different computer to where OBS is running the live stream. I don't fully understand all the connectivity in your configuration, but I don't think you can do what you are proposing i.e. USBC to USBC on another computer, expect it to recognize it as video. Somewhere in there you are probably going to need a capture card.

Here's what we do. The OBS computer (Windows 11) and the Keynote/Slides computer (iMac/MacOS) are side by side. The HDMI output from the Slides computer, which is feeding the sanctuary projectors, is split (1 HDMI in; 2 HDMI out) - one of the output cables continues on to the projectors, the other output cable goes into an HDMI Capture Card which is connected (with USB-C) to the OBS computer. And this is recognized by OBS as a Video Capture Device.

The other option I considered is NDI. It might work for you if both your computers are on the same network; and even if they are on different networks, I believe it can still be done.

There are several posts in the forum on this topic, including this: https://obsproject.com/forum/threads/screen-sharing-mac-to-windows.170467/

Cheers. . .
