An alternative approach that I've taken is to have the HDMIs from my work desktop plugged into a capture card on my main Windows desktop. I then use the preview from OBS to see the display and also hear the audio. Still need a separate keyboard + mouse, but I like being able to move/minimize my work OBS window off to the side when I'm not actively working. I also use this setup with gaming consoles so that I don't have to dedicate an entire monitor. https://github.com/obsproject/obs-studio https://github.com/obsproject/obs-studio

How's the latency?

  I don't notice it when using it for work. I barely notice it when using it for console games. Probably wouldn't want to use it for competitive shooters, but non-issue for most other games. Few more notes: - I use PCIE rather than USB for the capture card - Can be costly if you need 4k + multiple inputs (for multiple "monitors" as different OBS windows) - I had issues getting the capture card to recognize scaled HiDPI resolutions from my work Mac

    You can do this without a capture card using https://ndi.tv/tools/ https://ndi.tv/tools/ - other clients on your LAN can view in OBS or with the included program. I'm yet to try it with 4k. No help with consoles of course, and perhaps not an option for a work machine. edit: feature list also mentions "KVM remote control of any workstation running Scan Converter from NDI Studio Monitor"

      I use NDI a lot, but with a phone as webcam, or from obs to obs, scan converter, audio stream between devices like ipad/iphone/Android to desktop... But it is demanding to encode this way. HDMI capture does only use bandwidth over the USB or pcie bus, while ndi uses cpu or gpu.

        It's not at all demanding on my RTX2060 but I'm only doing 1080p 60fps - don't know how other cards/resolutions/framerates compare.

        HDMI capture cards can definitely use CPU, and this is the case for most USB capture cards as USB does not have enough bandwidth to send an entire raw stream in realtime.

        Yes, it's MJPEG for the cheap ones.

      You have hardware devices for ndi, but they ain't cheap!

I wrote a very simple html5 webapp which does this http://webcam.apps.gbraad.nl http://webcam.apps.gbraad.nl never got around to mute the audio or so, but patches welcome! I use two capture cards and them on th bottom monitors when needed (use 4 screens). This way I can also easily stream and records the screens when on a meeting that is on another machine.

You could use synergy to keep the same keyboard and mouse.

If you're doing this, why not use barrier or something like that? Iirc, it does have audio forwarding as well?
