Start with the viewing task
A TV is a sensible starting point for a small audience looking at a product demonstration up close. Compare projection and a modular LED wall when you need a larger shared image. Projection needs a suitable surface and a clear light path; an LED wall needs a support structure, processing and power.
Write one sentence before requesting quotes: «Guests must read these slides from these seats», or «People passing the stand must notice this animation». These are different jobs, and they can lead to different displays.
LED wall vs projector: brightness, size and setup compared
The video wall vs projector question usually comes down to light in the room and the image size you need. A TV is the third option when the audience is close.
| Factor | LED wall | Projector and screen | TV (43–85") |
|---|---|---|---|
| Brightness in daylight | Emits its own light and stays readable in bright halls; outdoor IP65 screens for open air. | Reflected light: daylight and stage lighting wash the image out, so the light on the screen must be controllable. | Readable indoors; check reflections from windows and spotlights. |
| Size flexibility | Modular 500 × 500 mm cabinets build almost any width and height, flat or curved. | One unit gives a large image; size is limited by the screen, throw distance and brightness. | Fixed sizes; a bigger image means several TVs with visible bezels between them. |
| Setup | Ground stack or flown on truss, with a processor and power; the longest build. | Screen frame, lens choice and a clear light path, or space behind a rear-projection screen. | Stand or truss mount; the quickest to install. |
| Cost logic | Priced per m² per event day, from €84 per m² indoors; grows with the surface. | Quoted per projector, lens and screen; the image can grow without adding hardware. | Quoted per unit and stand; cost grows with every extra screen. |
«LED TV» in a product name does not mean a modular event LED wall: ask which technology the quotation describes. When several LCD panels form one image, keep important text away from the joins; Samsung explains the effect of bezel seams on content.
Check light and detail separately
For LED, a smaller pixel pitch supports closer viewing, but readable detail also depends on the content; our guide to pixel pitch and viewing distance shows how to choose it. Planar describes these viewing-distance factors. Test your densest slide, not only a showreel. For projection, a brightness figure needs context: room light and image size decide what is enough. Epson separates white and colour brightness in its projector brightness guide, and projection distance depends on the lens, as its installation tables show. An empty rectangle on a floor plan does not prove that projection will fit.
Two quick examples
A 3 × 3 m exhibition stand. Three visitors at a time watch a presenter demonstrate software. A suitably sized TV on a stand usually shows the smallest interface labels well and leaves room for the conversation. If the goal changes to attracting visitors from across the hall, compare a small LED wall.
A 120-person conference with windows. First check whether the window light can be controlled, where the last row sits and whether a projection route exists. Ask for two layouts, projection and LED, and review the same slide from the same seats. Audience size alone does not set the screen size.
How REX Lab handles LED walls, projection and TVs
- LED walls: indoor P1.9, P2.6, P2.9 and P3.9, outdoor IP65 from P3.9. Our own Warsaw stock is 200 Gloshine Dawn P2.6 cabinets (about 50 m², 800–1000 nits) with NovaStar processing, ground stacked or flown, and curved up to 10° per joint. See LED wall rental with crew.
- Projection: 4K laser projectors with front and rear-projection screens; see projectors and monitors.
- TVs: 4K TVs in 43", 55", 65" and 85", other sizes on request; see TV screen rental.
LED walls cost from €84 per m² indoors ground-stacked, from €95 flown and from €112 outdoors (IP65), net per event day, including delivery, installation, setup and dismantling. Above 20 m² the per-m² rate rises, so check your exact size in the LED screen calculator or read what LED screen rental costs. Projectors and TVs are quoted per event. Operator shifts are billed separately. When you compare offers, check that each covers the same display, delivery, installation, operator hours and content preparation. Main-hall LED screens at a corporate event in Bytom and at 100 years MAZOVIA SPORT CLUB show the result.

Frequently asked questions
Why are LED walls more expensive than projectors?
An LED wall is built from many cabinets, each a display in its own right, plus processing, a support structure and crew time to build it. A projector is one unit and a screen. In return, LED stays bright in daylight and can be built to almost any size.
Can a projector work in daylight or outdoors?
Only where the light on the screen can be controlled. In daylight or a bright hall the projected image washes out, so an LED wall, or an outdoor IP65 LED screen, is the reliable choice; after dark, outdoor projection can work.
When is a TV enough?
When the audience is small and close, such as a product demo on a stand or a screen at reception. We supply 4K TVs from 43" to 85"; a large shared image needs projection or an LED wall.
Can I project onto a wall instead of a screen?
Yes, if the wall is smooth, light-coloured and matte, but colour and evenness depend on the surface. A projection screen gives a cleaner image, and rear projection hides the projector behind it.
Is an LED wall better than a projector for a conference?
In a bright room or for a large stage backdrop, usually yes. In a room you can darken, with a clear light path, a projector can do the job; compare both with the same slide from the last row.
