The Mississippi Coast Coliseum has anchored the Biloxi beachfront since 1977. It seats 11,500 for concerts and packs in 15,000 for festival shows, and over the years it's hosted just about everything — arena rock and country headliners, WWE, Monster Jam, hockey, boxing title fights, and a 400,000-square-foot convention center next door. It sits right on Beach Boulevard, which means the marquee out front isn't just signage. It's the first thing tens of thousands of drivers see as they roll past the Gulf, and it's how the building tells the coast what's coming to town.
That marquee needed a new heart. We removed the aging LED and replaced it with a new double-sided 6.67mm HydraCore outdoor display — 23 feet wide by 18 feet 9 inches tall on each face, roughly 437 square feet of LED per side and about 874 square feet across both. Each face runs 1,056 by 864 pixels, sharp enough to carry event art and sponsor creative that reads clean from the boulevard. We handled the full job: manufacturing the display, pulling the old one, installing the new one, and training the Coliseum's team to run it.
The display is driven by Novastar processing with wireless content management, so the staff can push new graphics to both faces without climbing into the sign. Sealed to IP65 with Neutrik weatherproof connectors throughout, it was built from the ground up for a job most LED never has to do: living full-time on the edge of the Gulf.
The Coliseum's marquee sits a few hundred feet from open water. That's a punishing place to put electronics. Salt-laden air finds its way into every seam and eats through hardware that wasn't built for it. Humidity stays high year-round. The midday sun comes in hard and direct off the water, washing out anything that isn't bright enough to fight back. And this is hurricane country — the same building took heavy damage from Katrina in 2005 — so whatever goes up has to be ready for storm season every single year.
A standard outdoor display doesn't survive that for long. So we didn't spec a standard outdoor display. We sealed the cabinets to IP65 to keep moisture and salt out, ran Neutrik weatherproof connectors at every cable junction, and built the whole assembly to resist the corrosion that comes with beachfront air. The panels are high-brightness outdoor units chosen to stay readable in direct Gulf sun, and we ran the marquee double-sided so traffic moving both directions on Beach Boulevard gets the same crisp image.
The Result: A marquee engineered specifically for salt, humidity, and storm exposure — a display built to keep working in one of the toughest environments LED ever has to face.
