LED wall that fits
Under a 2.7 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 19.5 m wall a Absen A2 Pro wall runs 31 x 1 (5208 x 168 px, 310 kg, 5.7 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, River Room holds about 207 theater seats, 85 banquet seats at rounds of 10, or 58 classroom seats. Back row in theater is roughly 12.5 m from the downstage edge; the previz checks whether the bottom of the wall clears the heads in front.
