Projector rental in Seville
Projectors for conferences, presentations, weddings and open-air screenings. The choice comes down to two things: how much light there is in the room and how far away the equipment can be placed.

What it is and when you need it
A big, affordable image, as long as you control the light
A projector gives you a five-metre image for a fraction of the cost of an LED screen the same size. The trade-off is that it competes with the light in the room, and it loses that fight whenever the room is brighter.
When it's the right choice
Hotel function rooms, classrooms, theatres, conference rooms and any space that can be blacked out or at least dimmed. Outdoors too, as long as it's at night: a projection in a courtyard at eleven o'clock at night works perfectly. What doesn't work is projecting at midday or in a marquee with open sides; that calls for an LED screen.
What actually gets projected
Presentations and talks at conferences, corporate videos and results at company events, photos and videos of the couple at weddings, summer outdoor cinema in residential communities and courtyards, and image support at official ceremonies. In every case the projector comes with a projection screen: a white wall is not the same as a proper projection surface.
Lumens
How many lumens you really need
ANSI lumens measure the light coming out of the projector. There's no magic number: the right one depends on the image size and, above all, on how much light there is in the room. This is the table we use when quoting.
| Situation | Lumens | Typical use |
|---|---|---|
| Small darkened room, 2 – 2.5 m image | 3,000 – 4,000 lumens | Meetings, classrooms, training rooms |
| Hall with dimmed lighting, 3 m image | 5,000 – 6,000 lumens | Company presentations, weddings in a banqueting hall |
| Large hall with working lights on, 4 m image | 7,000 – 10,000 lumens | Conferences with delegates taking notes |
| Room with uncovered windows, 4 m image | 12,000 lumens or more | Even so, consider an LED screen |
| Outdoors at night, 5 – 6 m image | 10,000 lumens or more | Summer outdoor cinema, courtyards, façade projection |
| Outdoors in daylight | No projector will do | Here the answer is LED, without exception |
Lenses and distance
Where the projector can be placed
Throw ratio
Every lens has a throw ratio: the required distance divided by the image width. With a standard 1.5:1 lens, a 4 m-wide image needs the projector 6 m away. With a 0.8:1 short-throw lens, just over 3 m is enough. With a 4:1 telephoto lens it can be hung at the back of a room, 16 m away, and still project the same 4 m.
The three situations we come across
Long room. The projector is hung from the ceiling or placed at the back with a long-throw lens; it's the cleanest option because nobody walks in front of the beam. Short room or stage close by. A short-throw lens, which stops the speaker stepping into the beam and casting a shadow. No room for the projector in front. Rear projection: the projector goes behind a translucent screen and disappears from the audience's view.
Keystone, lens shift and why they matter
If the projector isn't centred and square to the screen, the image comes out as a trapezium. Digital correction (keystone) fixes this at the expense of sharpness; lens shift fixes it by moving the lens, with no loss of quality. Whenever the set-up allows, we always prefer to position the projector correctly rather than correct it in software.
Common mistakes
What ruins a projection
Skimping on lumens to save money. It's the most expensive mistake. An underpowered projector in a bright room gives a grey image that can't be read from row ten, and the saving isn't worth it.
Projecting onto a wall. A painted wall has texture, tint and shadows. A projection screen has uniform gain and sharp edges; the jump in quality is obvious.
Pointing the stage light at the screen. It happens all the time: the lighting on the speaker also lights up the screen and washes out the image. It's solved by re-aiming the fixtures and shaping the beam, but it has to be spotted during set-up, not during the event.
Not testing the speaker's laptop. Odd resolutions, USB-C outputs with no adapter, mirroring modes and full-screen presentations that won't start. Ten minutes of testing beforehand avoids that awkward silence.
Forgetting the video's sound. A projector's built-in speaker is no use in a room. The audio has to go to the mixing desk and out through the event's sound system.
What the rental includes
What arrives on the day
Projector and lens
The projector fitted with the right lens for your room's actual throw distance, not whatever lens happens to be on it.
Stand or table
Projection table, tower or rigged from a structure, depending on the space.
Signal cabling
HDMI with the usual adapters, and conversion to SDI when the cable run is long.
Screen
Quoted together with the projector: tripod, tensioned frame or rear projection.
Test with the client's equipment
We test the laptop or media player that will be used before the event starts.
Technician
Quoted separately. With several speakers bringing their own laptops, it's well worth it.

Frequently asked questions
Questions about renting a projector
How many lumens do I need for a wedding in a banqueting hall?
With dimmed lighting and an image about 3 m wide, 5,000 to 6,000 lumens is more than enough. If the hall keeps the lights on during the video, go up to 7,000 or change when the video is shown.
Can I project onto the wall?
You can, but it shows. The wall's texture, colour and shadows add to the image. If it's a formal event, put up a screen: it costs little and transforms the result.
What format should the slides be in?
16:9 unless we tell you otherwise. It's what projectors and screens use today. Material in 4:3 will display, but with black bars at the sides.
How far away does the projector need to be?
With a standard lens, around one and a half times the image width. If you don't have that distance, there are short-throw lenses; and if there's no room in front, rear projection. We need the room dimensions to choose.
Does it come with sound?
The projector has a built-in speaker, but it's only good enough for a very small room. For any event we route the video's audio through the sound system.
Can you project outdoors?
At night, yes, and it looks great. In daylight, no: however many lumens you throw at it, the sun wins. For daytime outdoor events the solution is an LED screen.
