COMMERCIAL VIDEO WALLS

A tiled LCD video wall typically costs £6,000 to £35,000 installed in the UK: around £6,000 to £15,000 for a 2×2 of 55 inch panels and £15,000 to £35,000 for a 3×3. A seamless dvLED (direct-view LED) wall starts at around £20,000 and passes £100,000 for large or fine-pitch walls. The price includes the panels or LED modules, mounting, the video wall processor, cabling and commissioning; content and support contracts are extra.

Direct-view LED video walls in the UK typically cost £4,000 to £12,000 per square metre supplied and installed, depending on pixel pitch, brand and brightness. Fine-pitch indoor LED at 1.2mm or 1.5mm sits at £8,000 to £12,000 per square metre; 1.9mm and 2.5mm pitches for receptions and atriums are usually £4,000 to £7,000 per square metre. Because the processor and structure are a fixed cost, small dvLED walls rarely come in under £20,000.

An LCD video wall tiles commercial-grade displays (typically 46 or 55 inch, such as LG, Philips, Sharp or Samsung video wall panels) into a grid. It is the cheaper option, but you always see thin seams between the panels. A dvLED (direct-view LED) wall is built from LED modules in cabinets, so the image is completely seamless, brighter and can be made to almost any size or shape. LCD panels stay sharp even up close, so pick LCD for control rooms, smaller walls and tighter budgets where thin seams are acceptable; pick dvLED for a seamless, large, bright or curved wall, with the pixel pitch matched to the viewing distance.

Pixel pitch is the distance in millimetres between LEDs, and it sets the closest comfortable viewing distance. The rule of thumb is 1mm of pitch per metre of viewing distance. Boardrooms and briefing centres where people sit within 2m usually need 1.2mm or 1.5mm. Control rooms with operators about 3m away work well at 1.9mm to 2.5mm. Receptions viewed from 4 to 6m are fine at 1.9mm or 2.5mm, and atrium walls viewed from 8m or more can use 2.5mm or wider without visible pixels.

A 2×2 or 3×3 LCD video wall is typically installed and commissioned in 2 to 3 working days. A 3 to 4m direct-view LED wall takes 3 to 5 working days including structural mounting, power and signal cabling, processor configuration and calibration. Larger atrium walls, or installs that need scaffolding or out-of-hours access, take 1 to 2 weeks. The install window is fixed after the site survey so you can plan around your operating hours.

We specify the processor as part of the design: Datapath FX4 and Aetria, Userful, Christie Phoenix and Extron Quantum for multi-source walls, and Samsung MagicInfo or CleverLive Pro where the wall mainly shows digital signage. The choice depends on how many sources the wall shows at once (two HDMI feeds is a very different job from 32 IP camera streams) and whether the content is signage, dashboards, operator workstations or live video.

Yes. Direct-view LED walls should have an annual support contract with preventative maintenance, calibration and a stock of spare modules from the same production batch, held on site or with a defined response time. Individual LED modules can fail over the life of the wall, and batch-matched spares can be swapped in minutes without a colour mismatch. LCD walls need less, but still benefit from annual checks for panel ageing and alignment. Support typically costs 8 to 12% of the installed value a year, and a well-supported wall lasts 7 to 10 years.

Usually, yes. Any wall-mounted display over about 100kg needs the wall or supporting structure checked, and a dvLED wall can easily weigh 150 to 200kg once cabinets and frame are included. Plasterboard partitions normally need a steel subframe or a floor-standing support. The site survey also checks power (dvLED walls need dedicated circuits), ventilation, network and access for the install, so none of it turns into an extra later.
