Most staff have a Dell Latitude 3520. Detailed specifications can be found if you right-click the Windows menu and select 'System'. Use the Table of Contents below to jump to an area of interest.
A monitor or classroom display can be set up to mirror what is on your PC screen or it can be an extended view. In Extended view the second display will only display the default screen image of your PC unless you drag a window over to the extended screen. Settings for these modes can be found in the Windows menu under Settings (gear shaped icon) --> System --> Display. If you are properly connected to a second display you will see options to mirror or extend the screens. If you choose to extend you will see rectangles, representing your screens, that can be dragged around to change where each screen is in relationship to the other. See 'Classroom Display Only Shows Desktop Screen' under the Problems tab for further information.
