There are a couple of options you can use to show just your content if that's what you mean:
View > Presentation Mode that automatically hides all of the UI, adds a black background, and scales the art to fit in window.
View > Screen Mode > Full Screen Mode that you can also tap F to cycle through the screen modes to get there. You would also need to use Ctrl (PC)/ Command (macOS) + 0 to make the content fit the screen. The background is still the pasteboard color, and the details at the very bottom of the screen are still visible.
