external monitor causing fan on new 16inch MBP

Hi -

I recently purchase a MBP 16 inch. When I plug it into an external monitor (same monitor i've used with other laptops) it is causing the fan of my MBP 16 to become very loud. Should the fan be working this hard with just an external monitor plugged into it?

MacBook Pro 16″, macOS 10.15

Unfortunately we have been dealing with this issue since the MacBook Pro 16-inch was released 6 months ago, several macOS updates and the issue is still there.

The best you can do is call Apple support and report the problem to their engineers, if enough people call to report the problem the faster they will fix it (if it’s a software issue).
