Shape approximate: the venue publishes area only, so this room is drawn as a square of equal area.
LED wall that fits
Under a 3.1 m ceiling with 1.5 m trim and 0.3 m clearance you get 2 rows of 500 mm tile flown, which is tight; ground-stack or go lower on trim. Along the 22.2 m wall a Absen PL2.5 Plus V2 wall runs 35 x 2 (7000 x 400 px, 546 kg, 11.2 kW).

|---|---|---|---|---|---|---|
| Absen KLCOB 0.78 | 0.78 mm | 29 x 3 = 87 | 17.4 x 1 m | 22272 x 1296 | 392 kg / 863 lb | 7.7 kW, 37 A @ 208 V |
| Absen PL2.5 Plus V2 | 2.5 mm | 35 x 2 = 70 | 17.5 x 1 m | 7000 x 400 | 546 kg / 1,204 lb | 11.2 kW, 54 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, Hall A holds about 908 theater seats, 371 banquet seats at rounds of 10, or 255 classroom seats. Back row in theater is roughly 15.2 m from the downstage edge; the previz checks whether the bottom of the wall clears the heads in front.
