AJA Control Panel Function Screens
Control Screen
The Control Screen is where you set the Default Output, what the device outputs
when no application has control of the board. This screen also has controls for
setting the genlock source, and for setting the Horiz and Vert timing offsets. The
top of the Control Screen shows the current state of the device and also shows
the name of the Application which has control of the board, if there is one.
Default Output
Many video applications can grab control of the Io 4K Plus, so its outputs can
change dynamically. The Default Output settings are used to select what will be
output when no third-party video application is controlling Io 4K Plus.
Video Output
• Input Passthrough - This selection directs Io 4K Plus to route video from its
selected input through the card for processing and output.
• Test Pattern - This selection directs Io 4K Plus to output a preset pattern
when no other application is in control. The pattern is selected from the Test
Pattern dropdown list below, or a graphic file can be chosen.
• Hold Last App - This selection directs Io 4K Plus to hold and output the last
frame of video from the last application to control Io 4K Plus. This can be
helpful when operating in an environment where you’re switching back and
forth between multiple application windows.
