Format Tab Screen
The Formats screen shows the video format currently in use by the Io XT framebuffer
(called the Primary Format) and allows you to change it. All throughout the Control
Panel, choices are always presented based on what Io XT can do with the signals
available and the inputs/outputs selected. For example, on the Format screen, if the
output or inputs are a different format than the primary, then you’ll see an additional
information pane that allows you to view and edit the secondary format—including
control over whether up/down/cross conversion is employed.

Format Tab Screen Settings
Video Format (Primary and Secondary)—these pull-down menus show the
currently selected formats. If you select an alternate value in the Primary Format
using the pull-down, it will change the format used by Io XT's framebuffer. When
a change is made via the Video Format pull-down or by clicking an icon (widget)
and selecting a new format via a contextual menu, the block diagram will change
to reflect the new format. In the case of a Secondary Format, the formats
available can vary based on what the Primary Format is and the input signal
(frame rates of input sources limits the to/from conversion choices). The
“Secondary Video Format” pull-down menu lists all compatible formats for
selection (incompatible formats are not shown). This allows you to see what
you've chosen, and also see those formats that are compatible with the selected
Primary format.
The RGB Range pulldown menu allows you to select either Full range (0-1023) or
SMPTE range (typically 64-940) for RGB color output.
