to show the virtual Back panel.
Click the connectors to access their settings directly.
Tip :
Click Renumber All to update the I/O numbering if a number of available connectors was modified by replacing a card (e.g. Filler card or 8-HDMI card). Renumbering will restart the system and may affect the memories and other previous settings like inputs or backgrounds.
