Is it possible to completely hide the menu bar on an external monitor? I'm using my laptop with a projector, and while I can set the desktop background to completely black, the menu bar is still there. Even in dark mode there is still text. I would like to avoid showing any desktop UI if the presentation (Keynote) exits.

One possible workaround... Go into System Preferences. Select "General." Towards the top, there is a place you can set the menu bar to "Automatically hide and show the menu bar."
Try setting your dock to autohide while leaving the displays with separate spaces. Also make your video playing app fullscreen before using the fullscreen feature built into the app.
This answer says that the menu bar cannot be hidden, but it shouldn't be showing up in full screen unless you place your mouse over the top of the second monitor.

I think it's possibly 'Displays have separate Spaces' in System Prefs > Mission Control.
I've had that switched off since it was added to prefs, & only have a menu bar on my main monitor.
I don't want to switch it back to test, it messes things up ;-)
