Why does the device can’t popup Full Screen Monitoring?

Take the motion detection as an example:

1 Please check the below settings:Go to Menu> Configuration>live view>General>Event output, choose the event output. Please confirm the event output settings menu is the same with the real event output.

2 Go to Menu>Camera>Motion Detection >Enable Motion Detection, draw the detection area and sensitivity. Click Linkage Action to choose Full Screen Monitoring.
