- The brightness of a projector is a decisive factor for good image quality - especially in a school environment, where lighting conditions can vary greatly. As a general rule, the brighter the room, the more light output is required to ensure that content can be displayed with high contrast and clarity - even without complete blackout. It is therefore advisable to adjust the brightness of the projectors specifically to the respective location:Standard classrooms: In rooms with normal lighting and partial blackout options, the projector should have at least 4,000 to 5,000 ANSI lumens. This ensures that the image remains sufficiently bright and clearly recognisable even in daylight.Bright classrooms with plenty of daylight : In very bright rooms or with large window areas, 5,000 to 7,000 ANSI lumens are recommended in order to be able to show presentations, videos or digital blackboard images without any loss of quality.Assembly or multi-purpose rooms: These large rooms are often insufficiently darkened and have higher ceilings. For good visibility over longer distances, projectors with at least 7,000 ANSI lumens should be used here.Sports halls and large event rooms: Due to the long projection distance, the usually poor dimming options and the size of the area, particularly powerful devices are required here. A projector with 8,000 ANSI lumens or more ensures that convincing image quality is achieved even in difficult lighting conditions.Conclusion: When selecting a school projector, the light output should always be adapted to the spatial conditions. This is the only way to ensure that lesson content, presentations or media contributions remain clearly visible and legible regardless of the time of day and room size.
- The resolution of a projector largely determines the sharpness and detail of the projection. The higher the resolution, the clearer and finer the displayed content appears - particularly relevant when displaying texts, presentations, tables or educational videos. In educational practice, a sufficiently high resolution is crucial in order to be able to easily recognise information even from a greater distance. The most common resolution formats for school projectors areFull HD (1920 × 1080 pixels): This established standard provides a clear and detailed image quality that is perfectly adequate for the majority of school applications - whether for presentations, video content or interactive lessons. Full HD is an economical and proven solution, especially in classrooms.WUXGA (1920 × 1200 pixels): This resolution offers additional more vertical image area in 16:10 format. This is ideal for displaying text documents, spreadsheets or presentations with a lot of content. The additional space can offer real added value, especially in lessons with lots of written content or when using digital whiteboards.4K UHD (3840 × 2160 pixels): This particularly high resolution is particularly suitable for large projection surfaces or when displaying very detailed content, for example in science or technical subjects. 4K is also an interesting option for future-oriented investments in modern forms of teaching or multimedia presentations - albeit at a higher cost.Conclusion: Full HD is generally sufficient for everyday school use. If you need more space for content or even higher image quality - for example in specialist rooms, in the upper school or for school events - you can utilise more possibilities in the long term with WUXGA or even 4K. The choice of suitable resolution should therefore take into account both the didactic requirements and the planned area of application.
- The installation of a projector is generally straightforward and depends on whether you want to use it as a mobile device or install it permanently. Both options are suitable for everyday school life - depending on how flexible the use is planned.Connection options:Modern projectors have a variety of common interfaces that are compatible with most end devices in schools:HDMI - the standard connection for current laptops, computers or media playersVGA - still in use, especially with older devicesUSB - e.g. for direct media playback or for wireless adaptersLAN/WLAN - for integration into the school network or wireless presentations (depending on model)In many cases, an HDMI cable is all you need to connect the projector to your device - image and sound are transmitted in high quality.Installation types:You can choose between a mobile solution and a fixed installation:Mobile on a trolley: this variant is particularly suitable if the projector is to be used flexibly in several classrooms. The projector is simply set up, connected and moved as required.Ceiling-mounted: Ideal for fixed classrooms or larger areas such as auditoriums. The projector is securely attached to a ceiling bracket - the cables can be neatly routed via cable ducts.Tip: If you prefer a permanent solution, we recommend permanent installation by a specialist company. This way, you benefit from a tidy setup and trouble-free operation - a real advantage, especially in the hectic school day.
- Whether it's a classroom, seminar room, conference area or training centre - the right projector should suit the size of the room, the lighting conditions and the application scenario. Issues such as mobility, interactivity and connectivity also play an important role.
