What to think of when buying a video wall
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.
