LED wall that fits

Under a 7.4 m ceiling with 1.5 m trim and 0.3 m clearance you get 11 rows of 500 mm tile flown. Along the 30.2 m wall a Absen A2 Pro wall runs 48 x 11 (8064 x 1848 px, 5,280 kg, 97.7 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.
