Laptop is Acer Swift 2019. First, I have set screen display up in Win 10 for extended display.
When using Power Point I use F5 to launch slide show, a slide out menu comes out from right side, I press extend display to 2nd screen. Nothing happens, but if press again, the whole power point presentation reverses to other screen. However, if under "Slide Show" menu in PPt, if I manually click "Start Slide Show" it operates perfectly normally, leaving presentation view on laptop and sending the presentation slides to the 2nd screen.
These same slides work correctly on my desktop PC by using F5. Interestingly when F6 is pressed the laptop goes blank, and nothing happens on the 2nd screen.
In desperation, I have reinstalled windows 10, and Office 365, but still the same presentation issue. Have others encountered this problem? A I am missing something here.
