Projectors for every room – from classroom to lecture hall

Lecture halls

Bright installation projectors are the best choice for use in a lecture hall. On the one hand, these projectors can be mounted below the ceiling using a ceiling bracket - this saves a lot of space. On the other hand, installation projectors are usually so powerful that they can project a bright image even in illuminated rooms.

Our recommendations

Classrooms

Depending on the size of the classroom, short-distance and ultra-short-distance as well as installation projectors can be used here.

Interactive projectors in connection with a whiteboard are best suited for a teaching approach that is both interactive and uses multimedia.

Our recommendations

Multiple classrooms

For mobile use in different classrooms, projectors should have the following features: they should be compact and bright. Additional functions make operating easier or allow for a quicker setup of the projector. Useful and also popular functions are, for example, Direct Power-off for a fast shutdown of the projector and integrated media player for playback capabilities independent of the connected device.

Our recommendations

Projectors for school are also available with Wi-Fi. This allows for wireless transmission of various contents from your notebook or mobile devices, such as smartphones and tablets, to the projector. You will find out about everything you need to know about this in our Wi-Fi projector buyer’s guide.

Relevant information before you buy an education projector

Before you decide on an education projector, you should consider these three factors:

Room size

For every room, there is a suitable projector, which makes optimal use of the available space and thus delivers the best results. The choice of the projector type is essential here.

Image resolution

Image resolution is one of the most important factors when choosing a suitable projector for educational institutions. After all, the audience should be able to recognize all relevant image details of a presentation.

For satisfactory results, we recommend a projector with an image resolution from WXGA (1280 x 800) and upwards. This image resolution has established itself as the standard for a modern minimum image resolution. Furthermore, it matches the common 16:10 aspect ratio.

However, you should prefer a Full HD projector over a WXGA projector, as Full HD is universally suited for large and small viewing distances. This also applies to WUXGA (16:10). This resolution is very common with presentation projectors.

Brightness

The brighter, the better – that is the rule of thumb for most presentation projectors. For rooms that can only be dimmed slightly, we recommend projectors with at least 3,000 ANSI lumens. For bright rooms powerful projectors with values starting from 5,000 ANSI lumens are absolutely necessary. For optimum picture quality, it is recommended to darken the room slightly.

The right projection screen for school

A projection screen should be selected according to the used projector and considering the room conditions. The screen type should also be taken into account. For example, stationary screens must be mounted on the ceiling or a wall beforehand. Mobile screens, however, are ready for use in just a few minutes. These screens can be flexibly taken to, set up and used in almost any classroom.

Screen type	Projector type	stationary	mobile
Tripod screen	mobile Beamer
Framed screen	ultra-short-distance projectors (not interactive)
Frame screen (mobile)	Installation projectors
Motor-driven screen	Installation, short-distance and standard projectors
Roll-up screen	Installation, short-distance and standard projectors

Learn everything about projection screens in our projection screen buyers’ guide.

Projector speakers: specifically for school & university

Often a presentation needs to be supported by convincing examples. In these cases a good audio playback capability is essential.

Essentially, you can choose from a projector with integrated speakers, a passive speaker system with an amplifier or an active speaker system. All these three alternatives have their advantages and disadvantages.

Speakers	Advantages	Disadvantages
integrated	no additional speakers necessary quick setup	only recommended for small rooms
passive	more flexible positioning large selection	need an amplifier
active	do not need an amplifier	positioning restricted by limited length of power and audio cable

Projector connections: the most important connections for a presentation projector

The most important connections depends on which devices you want to connect to the projector

Generally, you can also connect older playback devices such as video recorders to a projector. Most devices have analogue cinch connectors for audio and video signals. Some models are still equipped with analogue inputs for YUV component connectors. This allows for the easy use of older DVD and Blu-ray players.

However, most commonly used are HDMI and VGA connectors. Nearly every multimedia device, such as a notebook or a DVD player, has one of these ports. If you have the choice between HDMI and VGA, we recommend using the HDMI port. With HDMI, you get a much better image quality plus simultaneous audio signal transmission. VGA is only suitable for transmitting image data. It does not transmit audio signals.

Fore pure data transmission, most projectors are equipped with USB sockets or LAN connectors.

Interactive teaching with whiteboard, projector & document camera

Interactive whiteboards and document cameras immensely increase the quality of a class by adding interactive elements and a time-saving, efficient handling. In addition, they not only make it easier for the teacher to prepare and present the teaching content but also help learners to absorb the subject matter more efficiently. The involvement of students also increases the understanding of the material.

All advantages - interactive whiteboards & document cameras

• easy preparation of teaching content
• multimedia presentation of content
• modification and control of content in real-time
• manufacturer software with numerous templates
• easy reuse of stored materials
• inclusion of student devices (smartphone, etc.) for a better understanding of the teaching material

Document camera

A document camera, also known as a visualiser, is a cross between a scanner and an overhead projector. It transmits a real-time image of the objects placed underneath to a projector. The latter finally projects the image onto a projection surface, such as a screen or an interactive whiteboard. A document camera also enables working on simple paper just like it would be with an overhead projector. You would no longer need expensive foils. Three-dimensional objects such as books can also be presented with it.

All document cameras

Interactive whiteboard

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

You can choose from 3 solutions:
1. Document cameras with an interactive full whiteboard set
2. Interactive projector and an interactive whiteboard
3. Interactive full whiteboard set
