Case file
Direct-view LED, fine-pitch LCD and rear-projection video walls for command centres, lobbies, broadcast studios, control rooms and event venues.
| Pixel pitch | Minimum comfortable viewing distance | Typical use |
|---|---|---|
| Finer pitch (e.g. P1.5) | Closer | Close-viewed lobby and control-room walls |
| Coarser pitch (e.g. P2.5) | Further | Larger rooms with greater sightlines |
Rule of thumb: minimum viewing distance in metres roughly equals pixel pitch in millimetres. Actual sightlines are measured before recommending.
/ The discipline, in detail
How we approach video walls.
A video wall is not a row of screens — it is a single, calibrated canvas. We specify pixel pitch to the closest viewer, brightness to the ambient light, and colour gamut to the content. Mullions are eliminated where the design requires it; bezels are accepted where they earn their place.
We commission with calibration probes per panel, a documented uniformity report, and a controller capable of source-routing without latency. Servicing access — tools-free panel removal, redundant power, hot-swap controllers — is designed in.
On record
Every video walls engagement is documented end-to-end — design, programming, commissioning, calibration — and handed over with the files our successors would need if we were never to return.

AV-over-IP deployment realities: network discipline is the binding constraint, not the codec choice
AV-over-IP is a network deployment that happens to carry AV. The codec choice, the platform brand and the encoder count are the visible decisions; the multicast routing, the IGMP snooping, the QoS marking, the VLAN segregation and the BFD discipline are the invisible decisions that decide whether the deployment works. Why network discipline outweighs codec choice on real projects.

/ Plan it right
Video Walls — getting the brief right.
Common mistakes to avoid
- Choosing pixel pitch on budget instead of the closest viewer's actual distance.
- Ignoring ambient light — a lobby wall facing glazing needs brightness a boardroom specification never anticipated.
- No service-access plan — front-service versus rear-service decides the wall's position and depth before the finishes are designed.
- Forgetting the wall is a system — controller, sources, content workflow and cooling — not just a grid of panels.
- Underestimating structural load and heat — a large DV-LED wall is a structural and HVAC conversation, not only an AV one.
What to share before a quotation
- The wall location, the viewing distances and the mounting surface or structure behind it.
- Ambient light conditions across the day at that position.
- The content plan — sources, resolution, and who operates and updates it.
- Operating hours — continuous signage duty changes the specification.
- Power, cooling and service-access constraints at the position.
/ Frequently asked
Video Walls — what buyers ask first.
What pixel pitch do I need?
Minimum viewing distance in metres roughly equals pixel pitch in millimetres — a P1.5 LED wall is comfortable from 1.5 m, a P2.5 needs 2.5 m. We measure the actual sightlines before recommending.
Direct-view LED or fine-pitch LCD — which should we specify?
Direct-view LED is the right answer for any application where the wall is visible from far enough that the LED's pixel pitch (P0.9, P1.5, P2.5) suits the closest viewer. LCD video walls remain useful where ultra-thin bezels (1mm) and 4K-per-tile resolution at close distance matter — typically command-and-control rooms. Cost crossover is now around the 110-inch mark.
What's the right pixel pitch for a given room?
Rule of thumb: closest-viewer-distance in metres × 0.5 ≈ maximum pixel pitch in mm. A boardroom wall viewed from 3m comfortably needs P1.5 or finer. A lobby wall viewed from 8m can run P3. Outdoor signage is a different calculation again — we model each project.
How do you handle calibration across a multi-tile video wall?
Every panel is calibrated for colour, brightness and gamma at the factory and re-checked on site after installation using a spectroradiometer. The video processor (Userful, Datapath, AMX) handles edge-blending and uniformity correction. Quarterly recalibration during AMC keeps the wall looking like a single canvas as panels age.
What's the lifecycle of a direct-view LED wall?
Indoor LED walls run 80,000–100,000 hours to half-brightness — about 11–14 years at 16 hours/day. Power-supply modules are the typical first replacement at year 5–7. We hold spare LED modules and PSUs for active deployments so a panel failure is recoverable in hours.
Can a video wall display content from multiple sources at once?
Yes — a video processor (Userful, Datapath FX4, AMX N-series) routes any source to any region of the wall, in any layout, with low-latency switching. Most command-centre walls run 4–12 sources tiled simultaneously; lobby walls typically run a single curated channel.
Which LED and video-wall brands does TechnoGuru work with?
On the display side we work with families such as AERO, Samsung, Sony and LG, with BenQ and ViewSonic on the projector and panel side and Novastar processing and control on the LED side. Brand references here are for comparison and application guidance, not a statement of partnership. The final make and model are selected after the viewing distance, site dimensions, content type and mounting and service plan are reviewed.
What does the controller or processor do on a video wall, and how is it chosen?
The processor — for example Novastar on LED, or Userful, Datapath and AMX on tiled displays — handles the input routing, layout, edge-blending and uniformity across the canvas. It is sized to the source count, the resolution across the wall and the switching the room needs, chosen against the actual application rather than a fixed model. Final selection stays subject to the site dimensions, content type and service access.
