Controllers that drive this panel

All controllers →

Each cabinet carries 16,384 px, so a controller's port budget and total capacity decide how much wall it drives. Its receiving card is not published — confirm the control ecosystem with your supplier before ordering.

Counts assume one cabinet per port-chain hop at 60 Hz / 8-bit. Open INFiLED ORHL3978 in the calculator to lay out the real chains and validate them.
