Shape approximate: the venue publishes area only, so this room is drawn as a square of equal area.

LED wall that fits

Under a 3.7 m ceiling with 1.5 m trim and 0.3 m clearance you get 3 rows of 500 mm tile flown, which is tight; ground-stack or go lower on trim. Along the 25.6 m wall a Absen A2 Pro wall runs 40 x 3 (6720 x 504 px, 1,200 kg, 22.2 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.

Seating estimate

After a 12 x 7 m stage, O'Hare International Ballroom - 1 & 2 holds about 1,269 theater seats, 519 banquet seats at rounds of 10, or 357 classroom seats. Back row in theater is roughly 18.6 m from the downstage edge; the previz checks whether the bottom of the wall clears the heads in front.
