The quote says “HDR-capable.” The show file is SDR. Or the camera is HLG and the wall is still set for PQ. That mismatch is how rental and live buyers pay for a sticker and inherit clipped highlights.

The quote says “weatherproof.” The datasheet says IP54. The stage is open to the sky. That mismatch is how outdoor and rental buyers inherit wet receiving cards and a season of board swaps.

The wall looks perfect at doors. Mid-set, a vertical stripe goes black for a second, comes back, then does it again. Or the whole surface dies while the processor still shows content on its preview. Someone says “we bought dual backup.” Someone else asks which dual.

Pixel pitch and brightness get the brochure pages. Service direction decides whether your team can actually fix a dead module at 2 a.m. without tearing down cladding.

If you have been shopping fine-pitch indoor LED in 2026, you have heard two slogans. One says COB won. The other says MIP replaces COB. Both oversell.

Glue on Board (GOB) adds a cured protective layer over an assembled SMD LED module. It can improve resistance to bumps, dust, moisture and static — but it is not a universal upgrade over SMD or COB.

A 4K LED wall is a cabinet count and a hang load first. Plan kg, pick points, and ground-stack vs fly before you buy pitch — factory planning notes, not a rigging cert.

Rental houses often order cabinets from a brochure photo: clean aluminium, a pretty lock, a pitch number in the headline. The wall that goes up on Saturday night does not care about the photo. It asks for geometry — how wide and tall the surface must be — and for crew time — how many […]

Outdoor festival LED rental checklist: daylight nits, front/rear IP, wind as engineer work, main vs IMAG pitch, and generator sizing from average watts–not brochure peaks.

Measure closest pew for pitch, farthest seat for wall height, then round to cabinet grid. A church LED sizing worksheet—not a brochure pitch list.
