The scene determines the test. The ranges and methods below are project-planning examples; selected hardware, firmware, cabinet design and site conditions still govern the final acceptance criteria.
Background: multiple shutter settings and live switching. Process: test representative camera positions, frame rates, refresh behavior, genlock path and low-gray fields. Result: a recorded camera operating window rather than a universal “flicker-free” claim.
Background: persistent sources and close-view detail. Process: map primary and backup paths, verify source recovery, record brightness scenes and preserve configuration backups. Result: an operating runbook tied to an accepted canvas map.
Background: changing cabinet counts and short setup windows. Process: verify addressing, port loads, spare-route behavior and restore files before rehearsal. Result: a show-specific configuration that can be recovered without rebuilding from memory.
Background: long signal routes and event-critical cues. Process: test source switching, canvas synchronization, operator presets and recovery time under rehearsal conditions. Result: a timed response sequence for the screens that matter during play.
A product family must be checked against the real input count, output canvas, receiver-card load, backup architecture and workflow. Venue names are useful context, but they do not prove compatibility.
Useful when switching, scaling and LED output are intended to live in one operational surface. Verify input/output formats, output capacity, layer behavior and firmware support for the selected model.
Useful for larger or separated canvases where transport, routing and redundancy need their own design. Verify link distance, topology, recovery behavior and fault visibility with the installed network.
Useful when module batches, camera-facing walls or low-gray consistency require measured correction. Verify the camera, software, test environment, measurement geometry and how correction data is archived.
Closer viewing can favor smaller pitch, yet a denser canvas increases processing load, data paths, power density and calibration effort. The defensible choice is the largest pitch that still resolves required content at the nearest real viewer, then a sample test under expected light and camera conditions.
High output can help in daylight, but maximum output is not automatically the correct indoor set point. Visual comfort, black-level behavior, thermal conditions and lifetime expectations must be reviewed together. Record the operating scene instead of quoting a peak value without its test condition.
Provide nearest viewing distance, ambient light, source formats, camera workflow, active canvas and acceptable interruption time. The response can identify which values need a model sheet, sample test or on-site measurement.
