On the View tab in the dialog box of the ribbon command File | Options 
, you can make settings for the appearance of documents on the screen:
"Editing mode" section
Here, you can specify how slides should be displayed when you edit them.
▪Show scrollbars
| Here, you can select whether to display a horizontal and vertical scrollbar for slides. |
▪Show rulers
| Presentations displays two rulers (one vertical and one horizontal) for slides by default. If you want to hide the rulers, disable this option. |
| Note: This option can also be found directly on the ribbon tab View | Ruler  |
▪Show object boundaries
| By default, Presentations displays dashed lines around objects on a slide (for example, when inserting text frames) if the objects are not already sufficiently highlighted by their own border lines or fill colors. These dashed lines are only intended to reflect the position and size of the object on the screen; they will not be printed. If you want to hide these lines, disable this option. |
| Note: This option can also be found directly on the ribbon tab View | Object boundaries  |
▪Show unprintable characters
| If this option is enabled, tabs and manual line breaks will be indicated as symbols on the slides. These are only displayed on the screen; they will be neither printed nor displayed during the slide show. |
| Note: This option can also be found directly on the ribbon tab View | Unprintable characters  |
▪Show formatted text in outline view
| If this option is enabled, Presentations displays text with its actual formatting (font and font size) in the outline view and the mini outliner. |
▪Color mode
| Here, you can specify how colors are displayed in slides on the screen. The original colors are displayed with the default option "Colors". If you select "Grayscale" or "Black and white", the colors are reduced to shades of gray or just black and white. |
| Note: This option can also be found directly on the ribbon tab View | Color mode  |
"Full-screen show mode" section
Here, you can specify on which display and in which resolution slide shows should be displayed when they are run in full-screen mode:
▪Display
| If you have two displays connected to your device, you can specify here on which of them full-screen slide shows are to be displayed. |
| This is useful, for example, if you have connected a projector to the secondary port of your graphics card and want the slide show to be run on this projector rather than on the primary display. |
| Note: This option can also be found directly on the ribbon tab Slide show | Display. |
Tip: We recommend that you select the setting Auto (which is also the default setting) here. This uses the primary display by default when playing a slide show – as long as no second display is available. As soon as you connect a second display and start the slide show again, Presentations automatically plays it on the second display.
▪Use presenter view
| Here, you can enable or disable the Presenter view. |
| If two displays are connected to your device and you start a slide show, it is displayed by default in the "Presenter view". This is a useful tool when running a slide show on a second display, for example, a projector: If it is enabled, the audience sees the normal slide show, while the presenter himself sees useful additional information on his own display – such as his notes on each slide. |
▪Screen resolution
| Windows only: This option allows you to change the resolution in which slide shows are displayed when run in full-screen mode. |
| You should usually select the default setting Use current resolution here. The resolution currently set in your Windows system is then used for the output device. |
| If you want to use a different resolution for your slide shows, select it from the list. |
