How to get the right video wall - Buying Guide

Thinking About a Video Wall? Here’s What You Need to Know — Technically and Practically

If you're thinking about investing in a video wall for your school, business, venue, or public space, you're not alone. But navigating LED vs LCD, pixel pitch, brightness ratings, control systems, and mounting options can quickly become overwhelming. That’s where Just Displays steps in — to make sense of it all and help you find a solution that performs, lasts, and fits your budget.

Understanding the Purpose of Your Video Wall

Before we talk specs, the first step is clarity on the end use. In a primary school, it might be about transforming a hall into a vibrant presentation space. In secondary or college settings, it’s about real-time content display or immersive learning. In a business boardroom, it’s high-clarity data display or remote conferencing. In museums or entertainment venues, it’s about delivering rich, engaging, visual experiences under challenging lighting and spatial conditions.

LCD or LED? Choosing the Right Technology

LCD video walls are modular and typically made up of narrow bezel panels. They're best for controlled-light environments such as classrooms, meeting rooms, and indoor signage. Expect crisp visuals at Full HD or 4K, though you’ll see faint bezels between each tile.

LED video walls are bezel-free and highly scalable, ideal for larger venues, digital signage, and areas with high ambient light. Pixel pitch is critical — a 1.8mm pitch gives excellent results for close-up viewers, while 2.5mm+ is suited to larger halls or outdoor areas. LED offers higher brightness (1000–8000+ nits), longevity (up to 100,000 hours), and seamless visuals.

Just Displays supplies both LCD and fine-pitch LED options from trusted brands like Allsee, Hisense, Leyard, and others — with tailored advice on pixel pitch, viewing distances, and environmental suitability.

Brightness, Resolution & Colour Accuracy

Choosing the right brightness depends on your space. Classroom and corporate use? Around 500–700 nits is sufficient. Reception areas with natural daylight may need 1000+ nits. Outdoor or atrium spaces might require 3000–8000 nits or more to maintain clarity.

We ensure the resolution matches the viewing distance and content type. Close-range viewers need Full HD minimum, ideally 4K. Large hall applications benefit from high contrast ratios and wide colour gamuts — particularly for branded content or presentations with complex visuals.

Mounting, Infrastructure & Installation

Video walls are heavy, heat-generating systems that demand precision mounting and good airflow. Just Displays provides wall-mounted, mobile, or freestanding truss systems — all compliant with safety regulations, including in schools and heritage buildings.

We advise on space planning, cable routing, power requirements, and screen accessibility. Our modular mounting structures include pop-out frames for maintenance and tool-free service access. Where needed, we include integrated cooling or noise-dampening systems.

Content Distribution and Control

Your video wall is only as good as its control system. Just Displays provides dedicated video wall processors and IP-based controllers depending on the use case:

For education: We deploy CMS (content management systems) that allow teachers or staff to upload, schedule, and play videos, announcements, and teaching content across the wall.
For business: Our setups support HDMI, DisplayPort, and AV-over-IP standards to show dashboards, presentations, and live data feeds.
For public venues: We install systems capable of 24/7 operation with remote access and failover redundancy.
Want to divide the wall into zones? Layer over live text or stream from multiple inputs? We’ll help you choose the right control interface and provide training for your staff.

Sector-Specific Advice

Primary Schools: We recommend LCD video walls with anti-glare coatings, Full HD or 4K resolution, and tempered glass for safety. These are ideal for morning assembly displays, phonics sessions, and visual learning in open halls.

Secondary & Sixth Forms: You’ll benefit from higher resolution and seamless integration with your IT network. Whether it’s live science demos, displaying exam timetables, or showing sports highlights — a video wall enhances it all. Control via local PC or central admin hub is often key.

Colleges & Universities: Go large with fine-pitch LED and networked control. Broadcast live lectures, display research data, or create digital signage across campuses. Our systems integrate with AV platforms and support multicast distribution.

Business Environments: In boardrooms, we deploy high-resolution LED with conferencing integration (Zoom, Teams), allowing hybrid collaboration and polished presentations. In reception spaces, high-brightness displays show branding and real-time feeds — synced to your CMS or social platforms.

Large Venues: From museums to concert halls, we deliver high-refresh-rate, wide-angle, weather-resistant LED video walls with flexible control. Whether showing live performances, wayfinding, or immersive content, we ensure your system is ready for constant public use.

Lifespan & Maintenance

Expect 50,000–100,000+ hours depending on the display type. We specify LED modules with low failure rates and tool-free servicing. You’ll benefit from reduced power consumption, automatic brightness calibration, and modular maintenance — keeping TCO (total cost of ownership) low.

Cost and How to Save

Video walls vary from £1,000 per square metre (LCD) to £10,000+ for premium LED systems. But you don’t pay list. Just Displays secures first-bid manufacturer pricing — which means if you're early in your area or part of a MAT or trust rollout, you can access significant savings.

We also offer leasing, allowing you to spread payments over multiple years with inclusive support, warranty, and optional upgrades. It’s a smart way to deploy tech now and align with future budgets.

See It for Yourself

Before you commit, we can arrange a no-obligation demo (in person or online), bring a test setup to your site, or guide you through a similar install we’ve managed. You can assess brightness, sound, responsiveness, and UI in real-world conditions — not just in a spec sheet.
