Video Wall Technology Explained

Compare LED and LCD video wall technology, pixel pitch, brightness, bezels, processing and installation requirements for commercial spaces.

Video walls are infrastructure projects as much as display purchases: pixel pitch, brightness, processing, service access, and mounting decide the result.

Journey

Choose LED or LCD around viewing distance

Direct-view LED removes bezels and scales beautifully for large feature walls, command spaces and venues, but fine pixel pitch increases cost, processing requirements and installation precision. LCD walls remain practical where budget, brightness, service access and close-up inspection need to be balanced. The deciding factor is closest viewing distance: if viewers stand near the wall, pixel pitch and panel seams become obvious. Audico should also consider content type, aspect ratio, refresh behaviour and whether the client needs a seamless brand moment or a functional information wall.

Journey

Treat pixel pitch as a design decision

Pixel pitch is the distance between LED pixels, and it should be selected from viewing distance and content detail rather than from a spec-sheet race. Smaller pitch improves close viewing and fine text, but it raises cabinet cost, processing load and sometimes maintenance complexity. A lobby feature wall can tolerate a different pitch from a control room full of small data, and an auditorium backdrop may prioritise brightness and scale over close inspection. The correct pitch protects both image quality and budget.

Journey

Understand bezels and visual continuity

LCD bezels interrupt large images even when they are very narrow, which can be acceptable for dashboards, tiled information and some security applications but distracting for brand films or immersive visuals. LED can look seamless from the correct distance, yet cabinet alignment, calibration, colour uniformity and module replacement become more important. Visual continuity is also affected by content design: a layout made for a normal 16:9 display may not suit a custom wall. Audico should involve content stakeholders early too.

Journey

Plan mounting, power, cooling, and content

A successful video wall needs structural support, clean cable routes, ventilation, service clearance, source processing and a content plan that suits the actual aspect ratio. Power draw and heat output can be significant, especially for large LED walls, and front-service access may determine cabinet choice. The processor must support the required resolution, inputs, redundancy and scaling behaviour. Audico should also ask who will create, schedule and maintain content, because the wall’s visual impact depends on operational discipline as much as hardware.
