to make the projection quadrate.
The blue areas are the maximum projection areas. For whiteboards without hotkey or with hard
hotkeys, there should be 2cm margin between projection area and whiteboard inner frame. For
whiteboards with soft hotkeys, the projection area should not exceed the hotkeys.
Note:
1. In case you use 16:9 whiteboard, please choose the projector supporting the 16:9
projection mode.
2. The projection image must be within the active area of the whiteboard, otherwise the
whiteboard cannot work normally.
