Projectors for every room - from the classroom to the lecture theatre


Lecture theatres

High-brightness installation projectors are the best choice for use in a lecture theatre. On the one hand, these projectors can be mounted below the ceiling using a ceiling bracket - this saves a lot of space. Secondly, installation projectors are usually so bright that they can project a bright image even in well-lit rooms.


Depending on the size of the classroom, both short-throw and ultra-short-throw projectors as well as installation projectors can be used. Interactive projectors in combination with a whiteboard are best suited for multimedia and interactive lessons.

Several classrooms

For mobile use in changing classrooms, projectors should have the following features: They should be compact and bright. Additional functions simplify operation or make the projector ready for use more quickly. Practical and therefore popular functions are, for example, direct power-off for quickly switching off the projector and an integrated media player for playback independent of the playback device.

Projectors for schools are also available with WLAN. This allows you to wirelessly transmit various content from your notebook or mobile devices such as smartphones and tablets to the projector. You can find out everything you need for this in our WiFi projector buying guide.

This is important before buying a school projector

Before you decide on a school projector, you should consider these three factors:

Room size

There is a suitable projector for every room that makes optimum use of the available space and thus delivers the best results. The choice of projector type is crucial here.

Projector type
Room size
Short-throw and ultra-short-throw projectors
Short-throw and ultra-short-throw projectors are very suitable for small and medium-sized rooms. Especially if you want to use an interactive short-throw projector.
Projectors with conventional optics
Projectors with conventional optics, on the other hand, are very suitable for medium-sized to large rooms such as large classrooms and lecture theatres. However, this type of projector cannot be used for interactive applications.

Image resolution

Image resolution is one of the most important factors when selecting a suitable projector for educational institutions. After all, the auditorium should be able to clearly recognise all the relevant image details of a presentation. For satisfactory results, we recommend a projector with an image resolution of WXGA (1,280 x 800) and upwards. This image resolution has established itself as the standard for a contemporary minimum image resolution. It also corresponds to the common 16:10 picture format.

However, you should prefer a Full HD projector to a WXGA projector. This is because Full HD can be used universally for large and small viewing distances. This also applies to WUXGA (16:10). This resolution is widely used for presentation projectors.

Image resolution
Picture format
WXGA (1,280 x 800)16:10
WUXGA (1,920 x 1,200)16:10
Full HD (1,920 x 1,080)16:9


The brighter, the better - that's the rule of thumb for most presentation projectors. For rooms that can only be slightly darkened, we recommend projectors with at least 3,000 ANSI lumens. For bright rooms, bright projectors with values from 5,000 AN SI lumens are absolutely essential. For optimum image quality, we recommend slightly darkening the room.

The right projector screen for school

A projector screen should be selected to match the projector used and take into account the room situation. The type of screen should also be taken into account. For example, stationary screens need to be mounted on the ceiling or a wall beforehand. Mobile screens, on the other hand, are ready for use in just a few minutes. These screens can be flexibly taken to almost any classroom, set up and used there.

Projector speakers: Especially for school & university

Often a presentation needs to be supported by convincing examples. In these cases, good audio reproduction is essential. Basically, you can either opt for a projector with integrated speakers, a passive speaker system with an amplifier or an active speaker system. These three alternatives have their advantages and disadvantages.

Projector connections: The most important connections of a presentation projector


Which connections are the most important depends on which devices you want to connect to a projector. As a rule, you can also connect older playback devices such as video recorders to a projector. The majority of devices have analogue cinch inputs for audio and video signals. Some models are still equipped with analogue inputs for YUV component plugs. This means you can also use older DVD and Blu-ray players without any problems.

However, HDMI and VGA connections are the most commonly used. Almost every multimedia device, such as a notebook or DVD player, has one of these two connections. If you have the choice between HDMI and VGA, we recommend the HDMI connection. HDMI gives you significantly better picture quality with simultaneous audio signal transmission. VGA is only suitable for transferring image data. It does not transmit audio signals.

For the pure transfer of data, most projectors are equipped with USB sockets or LAN connections. Find out everything you need to know about how to connect a projector correctly. Here you can also find out how to connect a Mac via a Mini Displayport or USB-C cable.

Accessories for presentation projectors


Projector tests

Projector tests are the easiest way to align a projector and set the correct projection distance.

Anti-theft devices

Secure a presentation projector against theft with a simple Kensington lock or with a theft-proof metal housing.


Control a presentation wirelessly via a presenter and use the integrated laser pointer as a pointer stick.

Interactive lessons with whiteboard, projector & document camera

Interactive whiteboards and document cameras significantly increase the quality of a course by adding interactive elements and time-saving, efficient operation. In addition, they not only simplify the preparation and presentation of teaching content for teachers, but also help learners to absorb the subject matter better. Involving the students also increases their understanding of the material.


All the advantages - Interactive whiteboards & document cameras

  • simple preparation of lesson content
  • multimedia presentation of content
  • Modification and control of content in real time
  • Manufacturer software with numerous templates
  • simple reuse of saved materials
  • Integration of student devices (smartphone etc.) for a better understanding of the lesson material

Document camera

A document camera - also known as a visualiser - is a mixture of a scanner and an overhead projector. It transmits a real-time image of the objects placed underneath it to a projector. This then projects the image onto a projection surface such as a projector screen or an interactive whiteboard. A document camera also allows you to work on plain paper, just like on an overhead projector. You do not need expensive transparencies. It can also be used to present three-dimensional objects such as books.

Interactive whiteboard

An interactive whiteboard is a combination of a projector and a whiteboard. The projector projects an image onto the whiteboard, which can be interactively controlled and modified using finger gestures or a wireless pen. The content is usually supplied by a PC or notebook connected to the projector. In this case, you can use an interactive whiteboard with a conventional ultra-short projector or a simple whiteboard and an interactive projector.

You have the choice between 3 solutions:

  1. Document camera with a complete interactive whiteboard set
  2. Interactive projector and an interactive whiteboard
  3. Interactive whiteboard complete set
