Independent LED field guides

Practical tutorials for people who actually hang, power, and operate LED walls.

LED Tutorials is an educational resource for AV technicians, church volunteers, venue operators, and installers. Each guide walks through a real job-site task — choosing pitch, mapping cabinets, feeding ProPresenter, or tracking down flicker — without a sales pitch.

Planning12 min
How to choose LED pixel pitch for viewing distance
Match pixel pitch to the closest real seat, camera shot, and content type so the wall looks sharp without overspending on density you cannot see.
Planning13 min
How to calculate LED wall size and cabinet layout
Turn a desired 16:9 canvas into a cabinet grid, native resolution, and physical footprint you can actually hang or stack.
Signal14 min
How to set up a video processor / scaler for an LED wall
Build a processor canvas that matches the wall, set EDID and scaling on purpose, and keep a backup input ready for Sunday or load-in.
Signal14 min
How to map and configure Novastar (or generic) receiving cards
Load the right cabinet file, draw an accurate cabinet map, set data direction, and verify every module before the room fills.
Rigging13 min
How to hang and ground-stack LED cabinets safely
Choose flown versus stacked, use rated hardware, and run a safety process that protects people before it protects the picture.
Power14 min
How to power and cable an LED wall
Size circuits for running load and inrush, inject power on a grid, and daisy-chain data without exceeding port budgets.
Color13 min
How to calibrate brightness and color for indoor vs outdoor LED
Set nits for the room, match color temperature to cameras and house light, and avoid the “nuclear white” look that wrecks IMAG.
Troubleshooting14 min
How to troubleshoot dead pixels, modules, and flickering
Isolate whether the fault is a diode, module, ribbon, receiving card, data chain, power, or camera shutter — then swap the smallest part that proves it.
Playback13 min
How to connect ProPresenter and media servers to an LED wall
Feed a wall from playback with a locked resolution, a single scaler, and a backup machine — whether you use HDMI, SDI, or NDI.
Maintenance12 min
How to maintain and clean an LED video wall
Keep modules, fans, and firmware in a boring routine so the wall stays even, cool, and serviceable years after install.
