When planning a video wall installation, the focus often falls on the big, visual details: pixel pitch, screen size, resolution, and content strategy. But one of the most practical — and often overlooked decisions happens behind the scenes: how will your video wall be serviced and maintained?
Whether you’re investing in DVLED or LCD technology, understanding front vs rear serviceability can save you time, money, and future headaches.
What Does Serviceability Mean?
In simple terms, serviceability refers to how easily your video wall can be accessed for routine maintenance, repairs, and component replacements after it’s installed.
Since video walls are modular (built from multiple panels or cabinets) these systems are designed to allow individual units to be swapped or repaired without dismantling the entire wall. But how you access those components can vary significantly.
Front Serviceability
Front-serviceable video walls are designed so that all maintenance and component access can be performed from the front of the display. Technicians can remove modules, power supplies, and other parts without needing to reach behind the wall.
Advantages:
- Space-saving: Ideal for installations where rear access isn’t possible, such as walls mounted flush against solid surfaces.
- Faster maintenance: Less dismantling means reduced downtime during service.
- Architectural flexibility: Enables sleek, low-profile installations in tight spaces.
Considerations:
- Some designs require specialised tools to “unlock” or extract front modules.
- Depending on the manufacturer, the front service process might slightly limit design choices or increase initial hardware costs.
Rear Serviceability
Rear-serviceable video walls require access to the back of the display for servicing components. These systems are often used in larger spaces where walls are mounted on structural frames or when access to the rear is easy and part of the design.
Advantages:
- Simplified module design: Rear-access modules are often slightly more cost effective due to fewer front-facing service features.
- More ventilation options: Back access allows better airflow and cooling designs.
- Easier for high-volume environments: In large dedicated AV spaces like control rooms or broadcast studios, rear access allows for more traditional service workflows.
Considerations:
- Space requirements: Rear serviceability typically requires a catwalk, service corridor, or open back space behind the display.
- Longer access times: Reaching the rear can involve more physical infrastructure and time, especially in fixed installations.
So, Which Is Right for Your Project?
Choosing between front and rear serviceability depends on several factors:
| Consideration | Front Serviceability | Rear Serviceability |
|---|---|---|
| Space Behind Wall | Minimal or none | Ample space required |
| Maintenance Access | From the front | From the rear |
| Ideal Applications | Retail, lobbies, meeting rooms | Control rooms, broadcast, large venues |
| Cost Factors | Slightly higher (due to design complexity) | Often lower (simpler hardware) |
Our Expert Tip:
When designing your video wall setup, think not only about today, but about 3, 5, or even 7 years from now. Serviceability planning ensures your system stays operational and cost effective over its full lifespan.
At Direct View Solutions, we help clients assess their space, performance needs and service expectations right from the start. So the only surprises are how stunning your finished video wall looks.
