Why outdoor events need a designed system
Large-format LED screens and IMAG side screens with switching, so every guest sees speakers, performers and content in crisp detail. IMAG — image magnification — exists for one reason: so the person in row forty can read a face. The brief is visibility and legibility, not scenic design. Screen size comes from the furthest viewer: a usable rule is that text height on screen should be at least one fiftieth of the viewing distance for comfortable reading, which pushes side screens on a long ground to six metres wide and upward. Standard 16:9 formats are the right choice here, because content is a live camera cut and a presentation deck, both of which already live in that aspect and should never be letterboxed or stretched to fit a creative canvas.
Match the rig to the room
| Scale | Guests | Recommended setup |
|---|---|---|
| Seminar room | 100 – 300 | One 4 m x 2.25 m screen at P2.6, furthest viewer under 20 m |
| Conference hall | 500 – 1,200 | 6 m x 3.4 m centre plus two 3 m side IMAG screens, four-input switcher |
| Arena floor | 2,000 – 8,000 | Two 8 m x 4.5 m side screens at P3.9, flown, four-camera IMAG |
| Open ground | 10,000 – 25,000 | Two 10 m main screens at 5,000+ nits plus two delay positions at 80 m and 160 m |
| Stadium screening | 30,000 – 50,000+ | Four daylight screens or mobile LED trucks on the bowl perimeter, fibre fed |
Specification
| Specification | Detail |
|---|---|
| Typical pitch | P2.6 – P3.9 indoor IMAG, P4.8 – P10 outdoor and delay positions |
| Legibility rule | On-screen text height at least 1/50th of the furthest viewing distance |
| Standard formats | 16:9 at 1920 x 1080 or 3840 x 2160 native, avoiding non-standard canvases |
| Delay screen spacing | Additional positions beyond 70 – 80 m of audience depth |
| Outdoor brightness | 5,000 nits minimum for daylight, 7,500 nits in direct sun |
| Switching | Barco E2/E3, Roland or ATEM with scaling handled once at the switcher |
| Long-haul signal | Fibre or 12G-SDI to delay positions, never long copper HDMI |
| Lip-sync handling | Video delayed to match audio arrival at each screen position |
| Mobile LED | Trailer-mounted 15 – 40 sq m daylight screens, hydraulic deploy in under two hours |
Honest alternatives
- Projection screens instead of LED for IMAGOur verdict
In a darkened hall with controlled ambient light, projection delivers a larger image per rupee and is perfectly adequate. In any lit room, outdoors, or where a presenter stands near the surface, LED is the only reliable answer.
- One large centre screen instead of a side screen pairOur verdict
A centre screen is cheaper and simpler, and right when the content is a deck. For IMAG it fights the stage for attention and leaves the flanks with poor sightlines — side screens serve a wide audience better.
- Adding delay screens versus making the main screens biggerOur verdict
Bigger main screens help up to a point, then the limiting factor becomes angular size at distance. Past 70 to 80 metres a delay position is cheaper and far more effective than another two metres of main screen width.
