So, what are the options when mounting a video wall?

When installing a video wall, the mounting system is just as important as selecting the screens themselves.

Unlike a single digital signage display, a video wall needs to be installed with precise alignment across every screen to create a seamless, professional-looking image. Even a small variation can result in uneven gaps, screens sitting at different depths or visible misalignment across the finished video wall.

The mounting system therefore needs to support the size and weight of the screens, while also allowing for accurate adjustment during installation and future maintenance.

When selecting a video wall mounting solution, you should consider:

• Screen size and weight

• VESA mounting pattern

• Number of screens

• Wall construction

• Required depth of the video wall

• Front or rear access requirements

• Cable access

• Ability to make micro-adjustments

• Ventilation and heat management

• Future maintenance and screen replacement

• Whether the video wall is being installed into a recess

  
  

4 Video Wall Mounting Options

1. Wall mounting - Specialist micro-adjustment pop-in/pop-out video wall mounts

2. Floor-mounted video wall structures

3. Freestanding -video wall structures

4. Suspended or ceiling-supported video wall structures

   
   

There is also another option worth considering at the design stage: creating a purpose-built recess for the video wall. This can create an extremely clean, integrated finish, but it needs careful planning around ventilation, access, screen depth, cabling and the manufacturer's installation requirements.

Which option is appropriate will depend on the size and configuration of the video wall, the building structure and, importantly, how easy the screens need to be accessed for maintenance.

1. Wall mounting Specialist Micro-Adjustment Pop-In/Pop-Out Video Wall Mounts

For most LCD video walls, a specialist micro-adjustment pop-in/pop-out mounting system is the preferred solution.

These mounts are specifically designed for multi-screen installations and provide much greater control over the positioning of each individual screen than a standard TV or digital signage bracket.

The key benefit is the ability to make fine adjustments in multiple directions, allowing installers to achieve consistent gaps and ensure every screen sits perfectly flush with the others.

The pop-in/pop-out mechanism is particularly useful for maintenance. Rather than having to remove surrounding screens to access one display, an individual screen can be pulled forward from the video wall to gain access to the rear of the display and its connections.

This is particularly important when installing a larger video wall, where replacing or servicing one screen could otherwise become a time-consuming job.

Why use a specialist video wall mount?

• Precise micro-adjustment

• Consistent gaps between screens

• Screens can be aligned flush

• Pop-in/pop-out access for servicing

• Easier individual screen replacement

• Improved cable access

• Designed specifically for multi-screen installations

  
  

For a 2x2, 3x3 or larger LCD video wall, this type of mounting system provides a much more professional and serviceable installation than using cheaper individual fixed brackets.

2. Floor-Mounted Video Wall Structures

For larger video walls, particularly where the wall itself isn't suitable for carrying the full weight, a floor-mounted /supported structure can provide a robust alternative.

These systems transfer the weight of the video wall down into the floor rather than relying entirely on the wall structure.

They can be particularly useful for:

• Large LCD video walls

• Direct View LED

• Very large-format installations

• Walls made from lightweight construction

• Locations where wall fixing is restricted

  
  

The structure can be designed around the specific size and configuration of the video wall and can incorporate adjustment points to ensure the finished screens are correctly aligned.

The floor itself must, of course, be capable of supporting the additional load.

3. Freestanding Video Wall Structures

A freestanding structure can be an excellent option where you don't have a suitable wall behind the video wall, or where you want the installation to become a feature in its own right.

A bespoke steel framework can be manufactured to accommodate the required number of screens.

This approach is often used in:

• Reception areas

• Exhibition spaces

• Retail environments

• Events venues

• Corporate offices

• Showrooms

  
  

The structure can incorporate cable management, media players and other AV equipment.

For larger installations, the structure should be professionally engineered to ensure adequate stability and load capacity.

4. Suspended or Ceiling-Supported Video Walls

In some environments, a video wall can be suspended from the ceiling or supporting steelwork.

This can create a particularly clean installation where wall mounting isn't practical or where the video wall needs to be positioned away from a conventional wall.

However, this approach requires careful consideration of the building structure.

A plasterboard or suspended ceiling will generally not be suitable for supporting the weight of a large video wall on its own. Fixings need to be made into suitable structural elements such as beams or supporting steelwork.

Depending on the installation, structural strengthening may be required before the video wall can be installed.

This is something that should be assessed during the site survey, rather than left until installation.

Creating a Recess for a Video Wall

For some projects, the cleanest option is to build the video wall into a purpose-designed recess.

A recessed video wall can give the impression that the screens are an integral part of the architecture, delivering a flush to wall modern finish, rather than simply being mounted onto a wall. This can be particularly effective in reception areas, boardrooms, showrooms, retail environments and corporate spaces.

However, a recess needs to be designed around the specific video wall screens and mounting system.

It isn't simply a case of measuring the overall screen dimensions and creating a hole in the wall.

You need to consider:

• Overall screen dimensions

• Bezel width

• Required screen-to-screen gaps

• Mounting bracket depth

• Cable connections

• Ventilation gap to meet warranty details

• Heat dissipation

• Access for installation

• Future screen replacement

• Front or rear servicing requirements

• Manufacturer installation clearances

  
  

Be careful with recessed installations

One important consideration is manufacturer warranty requirements.

Different commercial displays have specific requirements for ventilation, operating temperatures and installation clearances. If a screen is installed too tightly into a recess, there is a risk of restricting airflow and causing excessive heat build-up.

This could potentially affect the screen's performance and, depending on the manufacturer's requirements, its warranty.

Always speak to a video wall specialist and check the manufacturer's installation parameters before constructing the recess.

At Windsor Displays, we would recommend agreeing the screen model, mounting system and installation method first, before finalising the dimensions of any architectural recess.

Don't Forget Power, Data & Cable Management

It sounds obvious, but power and data requirements are often overlooked when planning a video wall.

Each screen will normally require power, while the video wall may also require:

• Network connection

• Media player

• Video wall controller

• HDMI/DisplayPort connections

• Signal distribution

• Control cables

• Power distribution

  
  

Ideally, these should all be considered before the mounting system is installed.

Cable routes should be planned so that they don't interfere with the pop-out mechanism or prevent individual screens from being accessed.

For larger LED video walls, you may also need to consider the location of the LED controller, receiving cards and associated equipment.

Wall Construction Matters

Before choosing the mounting system, you need to understand what you're actually fixing into.

A video wall can represent a significant load, particularly as the number of screens increases.

Depending on the building, the mounting surface could be:

• Solid brick or blockwork

• Concrete

• Stud wall

• Metal framework

• Plasterboard

• Existing steelwork

  
  

A suitable fixing method needs to be established based on the construction of the wall and the total weight of the installation.

For larger or more complex video walls, a site survey is strongly recommended before finalising the mounting solution.

What About Future Maintenance?

This is one of the most important questions to ask before installing a video wall:

Q: "How will we replace one screen if it fails?"

A video wall might look fantastic when it is first installed, but accessibility can become a major issue if maintenance hasn't been considered.

This is why specialist pop-in/pop-out mounts are so valuable for LCD video walls. They allow an individual screen to be pulled forward without dismantling the entire installation.

For larger video walls, you should also consider:

• Access to power connections

• Access to signal cables

• Ventilation

• Replacement screen access

• Controller access

• Whether the screens can be serviced from the front or rear

A few minutes spent planning this at the design stage can save hours of disruption later.

Frequently Asked Questions About Video Wall Mounting

Q: Can I use standard TV wall brackets for a video wall?

Technically, individual screens can be attached to standard brackets, but this isn't generally the best approach for a professional video wall.

Standard brackets typically don't provide the level of fine adjustment and alignment required to create consistent gaps between multiple screens.

Specialist video wall mounts are designed specifically for this application and make installation and future maintenance considerably easier.

Q: Do video walls need to be mounted directly onto the wall?

No. Depending on the environment, a video wall can be wall mounted, floor supported, freestanding or suspended from structural elements.

The best option depends on the building, screen configuration and desired appearance.

Q: Can a video wall be recessed into a wall?

Yes, but the recess needs to be designed around the specific screens, mounting system and manufacturer's installation requirements.

It is important to consider ventilation, heat dissipation, cabling and maintenance access. Speak to a specialist before constructing the recess to ensure the finished installation meets the screen manufacturer's requirements and does not compromise the warranty.

Q: How much space is needed behind a video wall?

This depends on the screen and mounting system.

Some installations require very little rear clearance, while others need additional space for ventilation, cabling and maintenance access.

A pop-in/pop-out mounting system can provide front access, which can be particularly useful where rear access is restricted.

The Mounting System Is Part of the Video Wall

Buying the screens is only one part of creating a successful video wall.

The mounting system needs to be considered alongside the screen specification, wall construction, cable infrastructure, content hardware and future maintenance requirements.

For a professional LCD video wall, a specialist micro-adjustment pop-in/pop-out mount will often provide the best combination of precise alignment, a clean finish and easy servicing.

For larger installations, a floor-supported, freestanding or suspended structure may be more appropriate. And where an architectural finish is required, a carefully designed recessed video wall can create a particularly impressive result.

At Windsor Displays, we can help specify the appropriate mounting solution as part of the overall video wall design, from 2x2 LCD video walls through to much larger multi-screen installations and Direct View LED. We can also advise on the practical requirements around mounting, access, cabling, structure and installation before you commit to the final design.
