         | Agreed... but one problem with that is that you get the title

         | you can use a fullscreen projector, but I often don't have one.
         | Anyone know a workaround?

           | move the top menu out of frame.

         | huh, I routinely people see sharing their screen in 1080p on
         | zoom and even 9-10pt fonts are pretty legible

           | That's the point - zoom prioritizes shared screen content

           | screen.

       | If the author had, they would have discovered Hiroshi Ishi's

       | Having said that, I love the solutions he came up with. Very
       | clever and making good use of tech available to everyone.
