The View setting can be found in the User module and is set by each User account. In the User module set your Zoom level  which is located near the top next to the User name, and when you log in as that User the screen will be adjusted based on your preferred setting.

You can increase or decrease the zoom level for the screen you're currently viewing to your preferred level if desired by clicking on either of the 'mountain' icons on the lower left side of your window. This will not affect your User zoom settings.
