Control Screen The Io Express can be controlled by various software applications running on a host MacPro.
The Control Screen is where you select how the Io Express directs video used by application
software. This screen also provides control for configuring output timing for external
reference video and horizontal/vertical delay.
At the top of the Control screen, it will show the current Default Io Express output and the
application currently controlling the Io Express card (if there is one). For example, in the
screen shown here, the default output is Input Passthrough.

Control Screen Settings
Default Io Express Output—Here you select the output Io Express will use as the default
when no application has control of the board, like when the Finder is active. Since Io
Express can be controlled by either software applications or its own Control Panel, the
output can change dynamically. When you change video applications, they will usually
grab control of the Io Express inputs/outputs. When they don’t, these default settings
determine which Io Express inputs/outputs are active and set the formats.
