LED video wall planning explained, power and data calculations, panels per port, processor planning, pixel maps, and preproduction checklists for LED techs.
An LED wall is a math problem before it's a rigging problem
Every LED wall question in preproduction reduces to arithmetic on the panel's datasheet: how many cabinets fit the design, how many amps they pull, how many panels each data port can drive, and what pixel space the processor has to map. Get the math right and load-in is assembly. Get it wrong and you're renegotiating power with the venue at midnight.
Two numbers cause most of the trouble: max power vs. typical power (bid power on max, size distro conservatively), and pixels per port vs. panel resolution (which sets your daisy-chain limit). Both calculations are shown line-by-line in these guides, with the formulas, not just answers.
LED Wall Power Calculation: Watts, Amps, and Circuits, Calculate LED wall power step by step: panels × watts per panel, watts to amps at 120 V and 208 V, circuits at the 80% practice, and max vs average draw explained.
