Display Equipment
Events utilize a variety of Displays to provide important information to the Teams, Volunteers, Event Staff and attendees.
At a minimum, events should have:
- (1) Main audience display per division
- (2) Remote displays (alliance/teamwork rankings and solo match rankings)
- (1) Field timer per alliance/teamwork field
- (1) Field timer per solo match field
If there are other displays available at the event, it’s recommended to include:
- Additional Remote Displays, as desired.
Refer to the Venue Selection, Facility Planning & Field Layout article for more information.
Display Types
Main Audience Display
The main audience display is the most common type of display at events. It is a large display centrally located near the alliance/teamwork fields so that it is viewable by the teams and audience. These can be large TV or computer monitors, projectors with screens, or other devices with a well-sized display.
Remote Displays
Remote Displays are supplementary displays located around the event venue to provide additional information. These can be TV or computer monitors, projectors with screens, or other devices with a well-sized display.
Field Timers
Field timers are used next to fields to provide Teams a better view of the match time. They are typically smaller computer monitors (approximately 20”-24”), tablets, or laptop screens.
Connecting and Controlling Displays
- Displays need to be controlled by a device that is connected to the internet and has a web browser.
- These devices can be laptops, raspberry pi’s, or mobile devices. Or, some ‘smart’ monitors have built in web browsing capability.
- The devices can be connected to any network, as long as they are connected to the internet.
- HDMI hubs can be used to connect multiple displays with one device.
Event Partners should coordinate with the IT department and Event Technology Coordinator to identify suitable equipment to use for displays at the event.

Other Display Equipment Considerations
- When planning for the event, consider the placement of the displays to ensure they will have access to power and the internet.
- The match sounds are played through the main audience display and/or field timers. Ensure that the venue speakers are connected to the appropriate display devices to play sounds.
Scoring Tablets and Wireless Connectivity
- Stable Internet Connection: To run Competition Control application, live streams, update rankings, and share live results.
- Tablets : For real-time scoring input by field referees and scorekeepers. Can also be used for field timers.
- Tablet Charging Station: For charging tablets overnight or at lunch (model will depend upon the tablet cord type.
- Dual Band Router Wi-Fi Network: Secure and reliable wireless connectivity to provide WiFi to devices using Competition Control.
- Network Switch: (Optional) Extend the network to for more displays and other hard-wired devices, if needed. This is not typically needed unless you need to hardwire several devices to connect to the internet.
- Ethernet Cables: (Optional) For networking hard-wired devices (laptops, displays, RPis, etc.), if needed. This is not typically needed if devices connect wirelessly to the router.
- Gaffers Tape: (Recommended) For securing wires
Computers with Web Browser
- Laptops: At least one, ideally more, to run the Competition Control and handle administration. They can also be used for other remote displays. Devices will need a web browser for an Event Administrator to access Competition Control.
- Printer: At least one, ideally a monotone printer with a USB-style plug-in for quick printing for matches, judges reports, administrative tasks, and more.
- Raspberry Pis: One per field and one per display (laptops can be used instead of RPis). An SD card and SD card reader are required (included in this kit).
Audio and Visual Equipment
- PA System: For announcements, match calls, and updates to keep teams informed.
- Computer speakers: Connected to the devices at fields to play match sounds. If your PA system can connect to your laptop, then these speakers are optional.
Live Streaming Equipment (optional)
- Streaming Setup: Includes cameras, capture cards, and software like OBS to live stream the event.
- Cameras: To stream matches or provide video replays for spectators or virtual audiences.
