HDMI cable between MBP and 27" HP Monitor Mike. This was the same way I hooked up to my 2017 iMac when I was using BIAB 2024 ... But now, I'm HDMI'd to my MBP, and using the 2017 iMac as a Luna Display. Except for consistently getting the cursor to seamlessly move between all 3 screens, we seem to be okay. I suspect some of the cursor finicky-ness is due to getting use to the best access points which is a tad smaller than I'd like, so you gotta hit the right smallish area or you're hitting a wall.
