You have a Power BI report that will be rendered on a vertical display. You need to maximize the portion of the screen area used by the report. What should you do?

Configuring the Image fit setting in Canvas background only affects how a background image is displayed and does not change the overall canvas dimensions or aspect ratio.

To maximize the screen area on a vertical display, you must adjust the report page's aspect ratio. This is achieved by going to the Canvas settings in Power BI Desktop and setting a custom width and height, such as swapping typical width/height values (e.g., 960x540 to 540x960) to fit a vertical orientation.

'Personalize visuals' is a feature for end-users in the Power BI service to make minor adjustments to visuals in a report, not for report designers to modify the canvas size in Desktop.

Enabling the Pages pane in the Power BI service only controls the visibility of the navigation pane for report pages and does not impact the report canvas dimensions.
