LED wall that fits

Under a 6.1 m ceiling with 1.5 m trim and 0.3 m clearance you get 8 rows of 500 mm tile flown. Along the 37.9 m wall a Absen A2 Pro wall runs 60 x 8 (10080 x 1344 px, 4,800 kg, 88.8 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.
