Guide to screens and projection for business presentations

Direct answer

A screen wins with daylight, smaller rooms and slides with a lot of detail, because it produces its own light and stays sharp. Projection wins in large rooms and with a big audience in a space you can darken, because there you can put up a substantial image at relatively low cost. The three factors that decide the choice are the viewing distance of your back row, the incoming light in the room and the amount of detail in your image.

This guide walks through those factors step by step, gives rules of thumb for size and distance, and shows when multiple screens are smarter than one large image.

Screen or projection: the core differences

Before you look at sizes, it helps to understand what each type delivers. A screen is a light-emitting panel that works in almost any situation, regardless of the lighting in the room. Projection throws an image onto a surface and therefore depends on how dark you can get the space.

Criterion	Screen	Projection
Daylight in the room	Stays clearly readable	Fades, needs darkening
Maximum image size	Limited per panel	Very large possible
Sharpness and contrast	High, good for detail	Good in the dark, less so in light
Setup and risk	Predictable and fast	Needs alignment and a clear light path
Atmosphere and impact	Businesslike and crisp	Grand and cinematic

If you want to weigh this up for one specific room, the in-depth article on choosing between a TV screen or a projector will help you make the call.

Screen size and viewing distance

The biggest mistake with imagery is a screen that is too small for the room. You do not decide the size on gut feeling, but based on the distance to your furthest viewer and the content of your slides.

The rule of thumb for image height

Use the distance to the back row as your starting point:

• For slides with normal text: image height about a sixth of the distance to the furthest viewer
• For detail-rich slides with small figures or tables: image height about a quarter to a fifth of that distance
• For imagery and video without small text: an eighth can be enough

If your back row sits sixteen metres away and you show financial tables, you want an image height approaching three metres. That is easier to achieve with projection than with a single screen, unless you opt for a setup with multiple panels.

Sight lines and placement

Alongside the size, placement matters. Raise the image high enough so that people at the back can also look over the heads in front of them. Account for columns, chandeliers and a low ceiling. What you arrange for imagery and projection is closely tied to the rest of your setup, and you can read more about that in the solution for imagery, screens and projection.

Daylight and darkening

Incoming light is often the deciding factor. A room that looks fine in the morning can become too bright for projection because of the afternoon sun.

• A lot of daylight or lighting you cannot dim: choose a screen
• A room you can get completely dark: projection gives a large and cinematic image
• A mixed situation with partial light: consider a screen at the spot where the light comes in

Check this at the right time of day. If your programme peaks at four in the afternoon, assess the light at four as well, not on arrival in the morning. The checklist for technically inspecting a venue sets out exactly what to look for with darkening and window lines.

Multiple screens: when and why

One large image is not always the best solution. In wide or irregular rooms, people at the sides see a central screen at a sharp angle, or not at all.

Choose multiple screens if:

• The room is wide and the audience is spread out
• Columns or other obstacles stand in the sight lines
• You want to show both the speaker and the slides separately
• The room is too bright for one large projection surface

A commonly used setup is a central image for the slides with two smaller screens at the sides, or two equal screens to the left and right of the stage. For conferences and larger gatherings this is often the standard, as you see in the service for presentations and conferences.

Checklist for your imagery setup

Run through these points before you commit to anything:

1. Measure the distance to your back row
2. Determine the toughest requirement on your slides, usually the readability of small text
3. Assess the daylight at the time of your programme
4. Check the sight lines for columns, ceiling height and stage height
5. Decide between one image or multiple screens
6. Check the connections and aspect ratio of all laptops
7. Plan a moment to test the image in the room

Common mistakes

• Choosing a screen that is too small for the distance, so nothing is readable at the back
• Using projection in a bright room and being surprised by the washed-out image
• Forgetting that the afternoon light is different from the morning light
• Showing slides with tiny text, regardless of the image size
• Placing one central image in a wide room where the sides see nothing
• Not matching the aspect ratio, resulting in black bars or a stretched image

What HuurAV arranges

HuurAV looks at the room, the light and the sight lines and advises on the image size and setup that will actually work for your audience. We provide advice, delivery, setup, installation, on-site support during your programme and collection afterwards. You do not need any technical knowledge yourself: we translate the room and your content into a concrete setup and test it in advance. For the physical screens and large image walls you can turn to the service for TVs and large screens, and if you want to combine live imagery with cameras, that connects to the solution for livestream and recording.

Next step

Do you know the room and the distances, but are you unsure about the size or type of image? Have your setup checked, and you can be sure that everyone in the room sees your slides clearly. HuurAV works in Amsterdam and the surrounding area and thinks along with you from the first floor plan to strike-down.
