The grid you pick is determined by viewing distance, content type and budget — usually in that order. This guide is the long version; the short answer for most Indian deployments is at the bottom.
2×2 video walls — boardrooms, lobbies, branches
- Ideal viewing distance: 8–14 ft.
- Use cases: bank branches, hotel lobbies, small NOCs, boardrooms, training rooms.
- Controller pick: SEADA G44-HDMI (4-in/4-out, 4K@60) for clean presentation switching, or SolarWall Micro 8 if you need more inputs.
3×3 video walls — control rooms, retail flagships, command desks
- Ideal viewing distance: 14–25 ft.
- Use cases: police command centres, telecom NOCs, retail flagships, broadcast monitoring, university auditoria.
- Controller pick: SEADA SolarWall Micro 12 for FPGA-deterministic uptime, or Drita DT4000 (Windows) when you want software-rich workflows and scenario presets.
4×4 video walls — large NOCs, transport, defence
- Ideal viewing distance: 20–35+ ft.
- Use cases: city-surveillance, traffic command, oil & gas, defence operations, energy SCADA.
- Controller pick: Drita DT4000 (Windows or FPGA), or Jupiter Catalyst V for premium / boardroom-grade installs with Canvas software.
The viewing-distance and pixel-pitch crossover
For LCD walls, panel size dictates everything — pick the tile, multiply by the grid.
For LED, pixel pitch matters more than grid count. Planar PFI 1.5 mm at 14 ft; PFI 2.5 mm at 25 ft. The cabinet count gives you the canvas size; the pitch gives you the resolution. They're independent decisions.
Picking the controller — input count is the gate
Rule of thumb: count peak concurrent sources × 1.5 = controller input spec. The ×1.5 covers the source you'll add in year two.
- 2×2: 4–8 inputs is plenty.
- 3×3: 8–16 inputs.
- 4×4: 16–32+ inputs and IP-stream decode capacity.
Comparison table
- 2×2
- Boardroom, branch, lobby · 8–14 ft · 4–8 sources · SEADA G44-HDMI / SolarWall Micro 8
- 3×3
- Control room, retail flagship · 14–25 ft · 8–16 sources · SolarWall Micro 12 / Drita DT4000
- 4×4
- NOC, command, transport · 20–35 ft · 16–32+ sources · Drita DT4000 (Win/FPGA) / Jupiter Catalyst V
Cost ladder (indicative, India)
- 2×2 LCD wall + controller — entry-level project budget.
- 3×3 LCD wall + Drita controller — mid-range.
- 4×4 LCD or fine-pitch LED + Catalyst V — premium / mission-critical.
Pricing on request — published price guides are misleading because installation, AMC and panel grade dominate the build sheet.
How VVT helps
We've installed all three sizes across Bangalore — from a 2×2 retail wall on Brigade Road to a 4×4 NOC in Whitefield. We size the wall and the controller as one decision, not two.
