When you create a campaign, you can either use a setup layout or create your own. For checking the division resolution in both cases, you can place your mouse over the division thumbnail below the timeline header. If you create a campaign yourself, you can also see the resolution by clicking in the pencil icon below the chosen layout under the Screen Layout header. The data will be displayed in a pop-up window.
