Plan view

LED wall that fits

Under a 9.8 m ceiling with 1.5 m trim and 0.3 m clearance you get 15 rows of 500 mm tile flown. Along the 66.4 m wall a Absen A2 Pro wall runs 106 x 15 (17808 x 2520 px, 15,900 kg, 294.2 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.
