LED wall that fits

Under a 3.7 m ceiling with 1.5 m trim and 0.3 m clearance you get 3 rows of 500 mm tile flown, which is tight; ground-stack or go lower on trim. Along the 31.8 m wall a Absen A2 Pro wall runs 50 x 3 (8400 x 504 px, 1,500 kg, 27.8 kW).

Wall sizing assumes 1.5 m trim to the bottom edge, 0.3 m clearance under the ceiling, and a wall no wider than 80% of the longest wall. Weight and power are tile totals from the panel spec sheet; add processing, rigging, and cable.
