The broadcast display shows information about a single in-progress match. The screen is meant to be easily embedded into a live broadcast of the tournament. The tournament organizer can open the broadcast display by clicking the "Broadcast link" from the tournament's "Overview" tab.
Once opened, the links at the bottom will let you select a round in the tournament and then a specific match. Once you've selected a match, the top of the screen will display the data for broadcast.
Players will always be displayed in their tournament playing order on the broadcast view. The tournament organizer can change the playing order from the "Rounds" tab at any time.
