Peak watts size the circuit and the generator. Average watts size the electricity bill. How church and rental LED walls get both numbers wrong.

3840Hz vs 7680Hz is not a bigger-is-better contest. See what phones, PTZ, and cinema cameras actually capture, how factories inflate Hz, and what to put on the PO.

P2.6 vs P2.9 vs P3.91 rental LED: viewing distance, camera jobs, outdoor daylight, and which pitch to stock first for touring inventory.

Soft vs hard connection LED rental cabinets: SFR-S fast soft lock vs SFR-H rigid touring lock. Hang and stack, 500×500 / 500×1000, rear service.

Rent vs buy LED wall: treat 10–20 uses as a planning break-even, not a promise. Same-bin spares, used-wall color, and a P3.91 / 2.9 / 2.6 lineup.

How to choose an LED display: viewing distance sets pitch, light sets nits and IP, install type picks rental, fixed, or trailer, cameras set refresh.

COB vs SMD LED: SMD allows field pixel rework, while COB usually means a module swap. Close viewing, durability, and when COB is worth the cost.

LED screens are specced in nits, not projector lumens. Indoor 800-1500 vs outdoor 4500-6500+, and why you should not run indoor walls at 100%.

Indoor vs outdoor LED wall specs that matter: nits, IP65, and daylight festivals. Why you should not take indoor cabinets outside, even under a tent.

Choose LED display pixel pitch from viewing distance. P1.5 to P3.91 charts in meters and feet, and why a 12-foot-wide wall at P2.5 is not 4K.
