Wrapped up an LED wall build for APTA Expo 2026 in Chicago.

192 panels of ROE CB3, 48 wide by 4 tall, running 94 feet across McCormick Place and mapped to a clean 7,680 x 1,280 canvas. Brompton Processing, 8 x XDs connected via Opticon Fiber.

Two walkway openings are built right into the wall, and every run has a backup signal path behind it.

A wall this long leaves no room to wing it. Ballast goes in before the first tile, the structure gets checked against the drawings, and the build goes up row by row from the bottom. Once it's lit, every port gets tested and the redundancy gets proven, because a backup you've never tested is a guess.

That's the part people don't see in the finished photos. Every wall looks simple once it's running content. Getting there is mostly checklists and double checks, plus staying calm when something changes at the last minute. That's the standard we hold ourselves to on every install, and it matters most on a wall this size, where one small miss can turn into a long delay. Having a great team helps tremendously as well! 🙏
