- A mobile LED truck instead of a built screen
The honest comparison
- 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.
- A mobile LED truck instead of a built screenOur verdict
For a short build window, a site with no rigging, or a one-day outdoor screening, the truck is faster and often cheaper all-in. Built screens win on size flexibility, positioning and on looking like part of a set.
What you are comparing against
| 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 |
The technical reality
The switching layer is what distinguishes a working IMAG setup from a wall with a camera plugged in. A video switcher takes camera inputs, presentation machines, playback and remote feeds, and produces a programme cut plus separate outputs for the screens, the stage confidence monitors and any stream. Scaling is handled once, cleanly, at the switcher rather than panel-side. For outdoor daylight, screens need 5,000 nits or more, and mobile LED trucks are often the fastest way to deliver a large daylight-bright surface on a site with no rigging and a short build window.
Where the market is going
Indian clients increasingly specify for the camera as much as the room, fire sound, video and lighting from one timecoded cue list, and add a spectacle finale only where it earns its place.
