I have a presentation in PDF and I want it on full screen. How to get one?

When I use Preview full screen or slideshow I always get that black frame. I previously have had presentations in PowerPoint and there it works without any problems. What do I do now that I have a pdf?

How my screen looks like:

enter image description here

(I added the white box with black frame to hide the content of my slides, but that is not important, I want to know how to hide this thick black frame around it)

    Can you add a screenshot so we see what you see? Also, what is the size of the screen, what is the ratio the presentation is using (4:3, 16:9)?

  • Is this a screenshot? What kind of preferences have you set? What happens if you zoom a bit in Preview?

    What happens if you zoom in a bit within Preview. Does the black border disappear or does just the white part grow bigger?

Full Screen should work for Preview in the same way as any other app. Obviously, the 'background' outside of the page will be dark, but if the PDF page is zoomed to match, then you won't see any black edge.

  • No, it doesn't work. When I use powerpoint I have slide over my whole screen and with Preview I have a black frame around it.

This seems to be a feature of Preview in Monterey.

You may want to use a 3rd party PDF viewer instead. I tried with Skim, it uses the full screen in presentation mode.
