I replaced my DELL XPS 15 with a new MacBook Pro 16" but when I connect my HD projector to the MacBook Pro 16" via HDMI-to-USB-C adapter, it takes around five minutes (not 30 seconds, not 1 minute – actually an unreasonably long time) until the projector actually displays an image from the MacBook Pro 16".
The projector shows up instantly in System Preferences > Displays, but only shows black until some random point many minutes after connecting it. It seems to just pop up randomly at some point.
Never had any problems with it, and connecting the projector to my XPS 15 9560 instantly shows an image on my projector screen, as expected.
What is going on here? It seems extremely weird to me.
