Slightly off topic but I have the 16" Macbook Pro with maxed out graphics, and as soon as I connect my monitor, the fans start getting ready for lift-off (~5.6k RPM). It's a Samsung 4k 32" (DP 1.4 to usb-c).
I know this is a common issue but anyone else able to resolve this yet? It drives me crazy that this powerful machine starts sounding like jet just from connecting 1 monitor (Apple says it can support four 4k monitors).
The CPU and GPU don't look to be under any stress as such.
