Each cabinet carries 129,600 px, so a controller's port budget and total capacity decide how much wall it drives. Its receiving card is not published — confirm the control ecosystem with your supplier before ordering.

Counts assume one cabinet per port-chain hop at 60 Hz / 8-bit. Open Sharp LD-E121 in the calculator to lay out the real chains and validate them.

Frequently asked

How much power does the Sharp LD-E121 draw?
Each Sharp LD-E121 cabinet draws up to 125 W at full white and about 59 W with typical content — 617 W/m² max. A 10-cabinet wall therefore needs up to 1,249 W plus headroom.
What is the resolution of the Sharp LD-E121?
One cabinet is 480 × 270 pixels at a 1.25 mm pixel pitch (640,000 px/m²). About 8 cabinets side by side reach 4K width (≈ 4.80 m).
How heavy is a Sharp LD-E121 wall?
A single cabinet weighs 4.7 kg (23.2 kg/m²). A 5 × 3 wall of 15 cabinets weighs about 71 kg before mounting structure.
Is the Sharp LD-E121 suitable for outdoor use?
No — the Sharp LD-E121 is an indoor cabinet (IP20 front). Its 600 nits suit controlled lighting, not direct sun.
