If the screen contents are played without any problems on a notebook while editing and scrolling but after starting the presentation by pressing the F5 key the notebook freezes, this may be due to the following problems:
Your notebook has a display with a lower resolution than the video projector used and the higher video projector resolution is set in the graphics card dialog. In particular with nVidia graphic chips, full screen display may cause a conflict as the full screen is larger than the notebook display.
Solutions:
Disable the notebook display so that playback is only via the external output. If this is not possible, try the second option.
As an alternative, you can try to use an extended desktop. The settings can be made in the dialog box Display Properties which can be opened by right-clicking the desktop and selecting Properties.
highlight the second display
place a checkmark next to it
adjust the resolution for the external output
