About your 4-Way ScreenWall ElectriMask
Your 4-Way ScreenWall ElectriMask is a fixed frame with both vertical and
horizontal masking panels, enabling the viewer to obtain any aspect ratio.
The term aspect ratio refers to the format (width to height) in which your
video sources are produced. The masking panels are controlled by three
separate motors, allowing maximum control and adjustability.
