Truss-Hung Video Wall Guide
A truss-hung LED video wall allows a large modular display to be suspended above a stage, exhibition space, audience area, or event environment instead of relying on a floor-supported structure. This can create cleaner sightlines, preserve stage space, and position the display at the appropriate elevation for larger audiences.
However, a suspended LED wall introduces important requirements involving screen weight, truss capacity, rigging points, hoists, load distribution, structural approval, power, data, venue procedures, installation sequence, and qualified rigging personnel.
This Truss-Hung Video Wall Guide answers the most common questions about planning, rigging, installing, operating, and removing suspended LED video walls for professional events.
Frequently Asked Questions About Truss-Hung Video Walls
What is a truss-hung video wall?
A truss-hung video wall is a modular LED display suspended from an approved truss and rigging system rather than supported primarily from the floor.
The LED cabinets are assembled into a larger display and attached to appropriate hanging hardware. The complete system is then supported by an engineered or otherwise approved rigging arrangement appropriate to the venue and installation.
What is truss?
Truss is a structural framework commonly used in event production to support equipment such as:
LED video walls
Lighting fixtures
Speakers
Scenic elements
Projection equipment
Banners
Production hardware
The exact truss type and configuration must be suitable for the intended loads.
Why hang a video wall from truss?
A truss-hung configuration can provide several practical benefits:
Keeps support structures off the stage floor
Preserves backstage space
Improves audience sightlines
Allows greater screen elevation
Creates a cleaner stage appearance
Integrates with larger production rigging systems
Whether it is appropriate depends on the venue and event design.
Is a truss-hung LED wall better than a ground-supported wall?

An LED or video technician normally configures the processor and screen mapping.
Who operates the content during the event?
Depending on the production, this may be handled by:
Video operator
Presentation operator
Playback operator
Technical director
Does an LED technician need to remain onsite?
For professional events, onsite technical support is often recommended, particularly for large or complex suspended systems.
What happens if a cabinet fails during the event?
The technical team can diagnose the issue and determine whether it can be corrected without lowering the wall.
What happens if a motor has a problem?
Rigging personnel should evaluate any issue affecting the suspended structure.
Should the wall be lowered if there is a rigging concern?
The response should follow the established rigging and event-safety procedures.
Can the client move the truss themselves?
No.
Only authorized qualified personnel should operate or modify the rigging system.
Can venue staff move the wall?
Only personnel authorized and qualified under the venue and production plan should operate the rigging.
What happens after the event?
The suspended LED system is removed through a controlled strike.
How is a truss-hung LED wall taken down?
A typical strike may involve:
Ending video operation.
Preparing the work area.
Lowering the truss or screen.
Disconnecting power and data.
Removing LED cabinets.
Packing cabinets into road cases.
Removing hanging hardware.
Removing truss and rigging equipment.
Removing cables and distribution.
Loading equipment out.
Does strike require riggers?
Yes, where rigging equipment and overhead systems must be removed.
Can LED technicians remove the wall before riggers arrive?
The strike sequence should be coordinated with the rigging team and venue.
Does the wall have to be lowered before panels are removed?
Usually, yes.
Panels should be brought to an appropriate working position before dismantling.
Can a truss-hung wall be struck immediately after the event?
Usually, if the venue schedule and crew arrangements allow it.
Can strike happen overnight?
Yes.
Many venues schedule event-production strikes overnight.
Can strike happen the next morning?
Potentially, if the venue allows equipment to remain installed.
Do venues charge overtime for late-night rigging?
Potentially.
Labor rates vary by venue, provider, union rules, day, and time.
Can late strike increase the video wall cost?
Yes.
Additional labor and venue charges can affect total cost.
What should I ask the venue before planning a truss-hung video wall?
Ask:
Are approved rigging points available?
What are the point capacities?
Is house rigging required?
Are union riggers required?
What drawings are required?
Is engineering required?
What are the rigging deadlines?
Are motors provided by the venue?
Are lifts required?
What electrical service is available?
What are the load-in hours?
What are the strike rules?
What information should I send to the video wall company?
Provide:
Event date
Venue
Room
Stage dimensions
Ceiling height
Desired screen dimensions
Screen position
Desired screen elevation
Audience layout
Venue rigging information
Available rigging points
Venue rigging contact
Power information
Load-in schedule
Rehearsal schedule
Show schedule
Strike schedule
Cameras
IMAG
Presentations
Playback requirements
What information is needed to calculate a truss-hung LED system?
The production team may need to determine:
LED cabinet model
Cabinet quantity
Screen dimensions
Native resolution
Total LED weight
Hanging-bar weight
Truss weight
Motor quantity
Rigging hardware
Cable weight
Point locations
Point loads
Power requirements
Signal routing
How early should a truss-hung video wall be planned?
As early as practical.
Suspended systems usually require more coordination than simple ground-supported walls because rigging information and venue approval may be needed before load-in.
Should I reserve the LED wall before rigging is approved?
The display design can be developed early, but the final suspended configuration should align with approved venue rigging requirements.
What happens if the venue does not approve the rigging?
The system may need to be redesigned as:
Ground-supported LED
A smaller suspended display
Multiple smaller screens
Another approved configuration
Can a truss-hung design be converted to ground support?
Often, yes, if compatible support equipment, floor space, and venue approval are available.
Can a ground-supported design later be changed to rigging?
Potentially.
The change requires confirmation of rigging points, loads, hardware, labor, and venue approval.
What is the biggest mistake when planning a truss-hung LED wall?
One of the biggest mistakes is assuming that because a venue allows event rigging, the desired screen can automatically be suspended anywhere.
The actual installation depends on approved point locations, point capacities, screen weight, truss span, load distribution, venue procedures, and the complete production rigging plan.
What other truss-hung LED planning mistakes should I avoid?
Common problems include:
Ignoring screen weight
Selecting screen position before checking rigging points
Forgetting truss and motor weight
Ignoring cable weight
Underestimating rigging labor
Missing venue submission deadlines
Ignoring screen elevation
Failing to plan service access
Leaving insufficient installation time
Assuming rigging is included in the venue rental
