I have to show Prezi on a 3:1 screen.
Can I change the default aspect ratio of Prezi Next to 3:1?
Hello @mimi2393, I merged your post with the relevant thread.
You can select the default 16:9 ratio, or 4:3, but you can also turn this off, so you should be able to use it with your screen. Please, check this quick tutorial on how to access this feature
