Plan view

LED wall that fits

Under a 2.5 m ceiling with 1.5 m trim and 0.3 m clearance you get 1 rows of 500 mm tile flown, which is tight; ground-stack or go lower on trim. Along the 41.8 m wall a Absen PL2.5 Plus V2 wall runs 66 x 1 (13200 x 200 px, 515 kg, 10.6 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.

After a 12 x 7 m stage, State Rooms & Rooftop Terrace holds about 1,578 theater seats, 645 banquet seats at rounds of 10, or 443 classroom seats. Back row in theater is roughly 34.8 m from the downstage edge; the previz checks whether the bottom of the wall clears the heads in front.
