Designing a Simple Output Map

Establishing Clear Separation Between Screen Roles and Video Ports

Live presentation workflows frequently stumble when technical teams plug video cables into graphics cards or distribution amplifiers before defining what each canvas must display. An output map represents an explicit schematic showing how every logical canvas inside your presentation software routes to a specific hardware output port, transport converter, and ultimate physical display surface. Starting with physical connections leads to trial-and-error patching, whereas starting with an output map ensures every stage requirement gets dedicated processing bandwidth.

Begin this design phase by gathering the exact visual targets in the venue: the main auditorium projector, auxiliary side delay monitors, presenter confidence screens, and broadcast feeds. Treat each destination as an independent logical recipient requiring its own refresh rate, pixel boundary, and signal color space before touching the hardware switcher.

Fundamental Principles for an Uncluttered Output Plan

Keep your schematic simple enough that a second operator can trace signal origin in under ten seconds during a live rehearsal crisis. Follow four practical conventions when sketching and assigning outputs:

• Assign unique numerical designations to physical outputs matching their physical card ports (e.g., Output 1: DeckLink Port A, Output 2: DeckLink Port B).
• Group audience-facing screens under identical refresh rate profiles to prevent GPU clock drift between projection clusters.
• Separate stage confidence monitors into an isolated logical screen layer to eliminate accidental spill of presenter notes onto room walls.
• Document native panel resolutions, SDI formats, and EDID handshake requirements directly beside each mapped port box.

Step-by-Step Mapping Workflow in Production Environments

Translate your architectural plan into software configuration using an orderly sequence. First, name each software screen according to its physical function rather than generic numbers like 'Screen 1'. Use descriptive identifiers such as 'FOH Center Projection', 'Stage Left Confidence Wedge', or 'Stream ISO Key'. Second, match each identified screen to its dedicated GPU or SDI hardware device. Third, verify each feed by displaying an identification test card featuring the canvas name and raster coordinates. Confirming these markers on each physical screen guarantees that software layers target the correct physical monitors before loading presentation media.
