LED wall that fits
Under a 3.4 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 29 m wall a Absen PL2.5 Plus V2 wall runs 46 x 3 (9200 x 600 px, 1,076 kg, 22.1 kW).

| Absen PL2.5 Plus V2 | 2.5 mm | 46 x 3 = 138 | 23 x 1.5 m | 9200 x 600 | 1,076 kg / 2,373 lb | 22.1 kW, 106 A @ 208 V |

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, Main Hall holds about 1,327 theater seats, 543 banquet seats at rounds of 10, or 373 classroom seats. Back row in theater is roughly 22 m from the downstage edge; the previz checks whether the bottom of the wall clears the heads in front.
