I am setting up a cinema system based on G61RSL and HD621.

No HDMI switching required as only the AppleTV 4K will use the system. The Xbox and PS5 can use the projector built in speaker.

So I literally just need whatever (presumably HDFury) solution separates the single HDMI signal into an audio to pass to the HD621 and passes video straight through to projector. I know some of the boxes do video processing too but I don’t really trust myself to not make things worse.

Recommendations appreciated
