Hallo everyone, the videos I have in my powerpoint slides would not play while in presentation on external projektors or TVs. This occurs only on projektors or TVs but not monitors. This happenes on my old Laptop (Windows 8, Office 2013) and the new one (Windows 10, Office 2016). It is an issue that bothers me for years. It does not happens on laptops of my friends.
Background Info:
- Videos are running fine on internal laptop screen (in presentation mode)
- affects all video formats (.avi .wmv .mkv)
- with and without a dedicated graphic card
- with different cable and Connectors (HDMI, VGA, etc.)

Does anyone have some suggestions?
