LED wall that fits

Under a 9.1 m ceiling with 1.5 m trim and 0.3 m clearance you get 14 rows of 500 mm tile flown. Along the 177.7 m wall a Absen PL2.5 Plus V2 wall runs 284 x 14 (56800 x 2800 px, 31,013 kg, 636.2 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.
