A ground-supported LED screen is usually the practical choice when the floor can carry the complete system, there is enough footprint for the base and bracing, and overhead rigging is unavailable or unnecessary. A flown screen can free floor space and improve sightlines, but only where approved suspension points, qualified riggers, suitable equipment and a verified load plan are available. The final decision is an engineering and venue-approval question, not simply a preference for one appearance.
The decision in one table
| Project condition | Ground-supported screen | Flown screen |
|---|---|---|
| No certified overhead points | Usually the viable route, subject to floor and structure checks | Not viable without a separately engineered support system |
| Limited floor footprint | Bases, feet, outriggers and exclusion zones may be difficult to accommodate | Can preserve usable floor area if the roof and points are approved |
| Low ceiling or restricted trim height | Often easier to fit and level | Hoists, lifting hardware and safe clearances may consume too much height |
| Outdoor exposure | Requires a site-specific structure, ballast strategy and weather plan | Requires an engineered roof or tower system plus weather controls |
| Fast access at ground level | Assembly and service can be straightforward | Lifting operations and work at height require additional planning |
| Uninterrupted audience sightline | Structure may be visible at the sides or below the display | Often gives a cleaner lower edge and fewer floor obstructions |
This table helps with early planning only. It does not determine whether a particular floor, roof, truss or screen configuration is safe.
What ground-supported really means
A small indoor video wall may stand on manufacturer-approved base frames or feet fixed to a level stage or venue floor. Larger walls normally need a purpose-designed support arrangement that stabilises the display in every relevant direction. Depending on the brief, that may involve a truss goalpost, ground-support towers, or a modular scaffold system assembled from a proprietary product family. Layher is a manufacturer and system brand, not a generic name for all modular scaffolding.
Ground support is not synonymous with simply stacking cabinets. The design must account for the combined screen and structure, the surface beneath it, changes in level, public proximity, cable routes and access for installation. Outriggers and ballast may be part of the stability concept, especially outdoors, but their size, location and specification cannot be selected from a universal rule. They can introduce trip hazards, reduce backstage routes and create concentrated reactions on floors or paving.
Ground support is often effective in hotel ballrooms, exhibition halls and temporary stages where roof loading information is unavailable. For example, a conference screen against a solid rear wall may have generous backstage depth but no permissible ceiling suspension. A supported wall can work well if the loading dock, doorway, floor protection and base footprint have all been checked before delivery.
What a flown screen requires
A flown LED wall is suspended from an approved supporting structure using compatible hanging hardware and lifting equipment. It should not be assumed that any visible beam or house truss is a rigging point. The venue must identify permissible points and provide current information about their capacity and operating conditions. A qualified rigging provider then develops the suspension arrangement, lifting sequence and controls for working below or near the load.
Flying is valuable when stage depth is scarce, the lower edge must remain clear, or cameras and audience need an unobstructed view. An arena presentation may use documented roof points and established rigging access, making a flown wall efficient. The same proposal can be unsuitable in a listed venue with unknown roof data, restricted hoist access or no safe way to reach the points.
Outdoor flying does not remove wind risk. The screen, supporting roof or towers, motors, secondary safety provisions and operational weather plan must be considered as one system. Decisions about lowering, de-rigging or stopping use belong in the project-specific plan, not in an online rule of thumb.
Venue access can decide before aesthetics do
The intended structure must physically reach and fit the installation area. A city-centre venue may have a narrow goods lift that accepts LED cabinets but not long truss sections. A theatre may allow roof loading yet offer only a short overnight rigging window. A marquee may have no approved suspension points and a floor that cannot accept arbitrary concentrated loads. An outdoor courtyard may provide vehicle access but contain underground services that restrict anchoring and ballast placement.
A useful survey records loading routes, door and lift dimensions, stage and floor build-up, available footprint, ceiling height, approved points, power and data positions, fire exits, public circulation and working-at-height access. It should also identify who controls the venue and who can approve drawings and methods. Screen format matters too: review screen size and viewing distance and pixel pitch before designing a large structure around the wrong display specification.
Common mistakes to avoid
- Choosing flown rigging before the venue confirms usable points.
- Treating ground support as load-free because nothing hangs from the roof.
- Allowing feet, outriggers or ballast to obstruct exits, ramps or backstage traffic.
- Assuming an indoor structure can move outdoors without redesign and weather management.
- Pricing only the LED panels and overlooking rigging labour, access equipment, transport, floor protection and approvals.
- Leaving cable management and rear maintenance clearance until installation day.

FAQ
Is ground support always cheaper than flying?
No. It can avoid venue roof rigging, but larger bases, towers, scaffold, ballast, floor protection or lost seating space may outweigh that saving. Compare complete approved solutions, not isolated hardware prices.
Can an LED wall stand directly on a stage?
Only after the stage system, load distribution, screen hardware and stability arrangement have been checked for that exact use. A visually solid deck is not evidence of adequate capacity.
Is a flown screen safer because the floor stays clear?
Neither method is inherently safer in every venue. Each has different hazards and depends on competent design, installation, inspection and operation.
