Plan view

LED wall that fits

Under a 7.3 m ceiling with 1.5 m trim and 0.3 m clearance you get 11 rows of 500 mm tile flown. Along the 58.8 m wall a Absen PL2.5 Plus V2 wall runs 94 x 11 (18800 x 2200 px, 8,065 kg, 165.4 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, Columbia Ballroom holds about 3,759 theater seats, 1,537 banquet seats at rounds of 10, or 1,057 classroom seats. Back row in theater is roughly 51.8 m from the downstage edge; the previz checks whether the bottom of the wall clears the heads in front.
