The Viewing Grid is the empty background of cells into which items (devices, Showreels, web pages, local files, etc.) are placed to create a Layout.

Viewing Grid cells are only visible when you move or resize objects in the layout. Green cells indicate where an item can be placed, red cells indicate where it will not be placed.

The Viewing Grid has a default cell aspect ratio of 16:9, currently the most common aspect ratio of cameras on the market. The cell aspect ratio can be set using Change Cell Aspect Ratio from the from the Viewing Grid context menu.

Note that t he cell aspect ratio adapts to the first item placed in layout. This is important to consider when designing your layout. E ach item added to a layout will display in its native aspect ratio, but no matter what the aspect ratio of subsequent items placed, the cell aspect ratio is determined by the first item placed in layout.

The Viewing Grid has a setting for the spacing between cells (none, small, medium, or large) which is useful when you need to make a layout more compact. Access this control from the Viewing Grid context menu choose Change Cell Spacing.

There is also a setting for the default display resolution (auto, low, high), controlled from the Viewing Grid context menu -> Change Resolution.

IMPORTANT: The Viewing Grid adjusts to the aspect ratio of the first item added to a layout.
