Acer S1287 XGA short-throw projector for classrooms and conferences with TR 0.62

Acer S1287 – XGA short-throw projector with 4,000 ANSI lumens for classrooms, training rooms and conferences

The Acer S1287 is a DLP short-throw projector with 4,000 ANSI lumens and native XGA resolution (1,024 × 768 pixels). The fixed throw ratio of 0.62:1 produces a large image from a very short distance to the projection surface. Teachers and presenters thus stand outside the beam – the projection remains free of shadows and glare. Weighing 3.1 kg and backed by a 36-month manufacturer's warranty, the S1287 is designed for continuous use in schools, universities and companies.

Benefits and special features

• 4,000 ANSI lumens – clear images even with normal room lighting in the classroom
• Short-throw lens (TR 0.62:1) – large image from a short wall distance, shadow-free projection for the presenter
• Portrait mode and 360° operation – flexible mounting horizontally, vertically or inverted for digital signage and unusual installation positions
• LAN with Wake-on-LAN – the projector can be switched on remotely via the network without entering the room
• Direct Power On – starts automatically when mains power is applied, ready for immediate use
• Keypad lock – the control panel can be locked so that only remote control operation is possible (anti-tampering function)
• Password protection – protects settings against unauthorised access
• Quiet in operation – 29 dB(A) in Normal mode, 27 dB(A) in Eco mode
• 36-month manufacturer's warranty – one year longer than the market standard

Applications: what the Acer S1287 is ideal for

Classrooms and training rooms

With 4,000 ANSI lumens and a throw ratio of 0.62:1, the S1287 is particularly suitable for rooms where the wall distance is limited. The short-throw lens places the projector directly above or close to the projection surface – the teacher moves freely in front of the board and always stays outside the beam. The 29 dB(A) noise level in Normal mode stays discreetly in the background during everyday lessons. Direct power-on mode switches the projector on automatically as soon as power is applied – lessons can start straight away.

Conference rooms with a compact wall distance

In conference rooms with limited depth or a mounting position close to the wall, the short-throw lens with TR 0.62:1 delivers a large image at a short throw distance. LAN with Wake-on-LAN allows remote switch-on before a meeting starts – the IT department or room control system can activate the projector centrally. RS-232 integrates the device into existing media control systems.

Digital signage and flexible installation

Portrait mode and 360° operation allow projection in any orientation: vertical for narrow displays, sideways or inverted on the ceiling. This means the S1287 can also be used for info displays, trade fair installations and unusual room geometries – the room geometry determines the mounting position, and the projector adapts.

Picture and sound quality, connections

The S1287 uses single-chip DLP technology with a 0.55" chip in XGA resolution (1,024 × 768 pixels, 4:3 format). The dynamic contrast of 20,000:1 ensures clearly differentiated text on bright slides and good black reproduction with visual content. HDR signals from compatible HDMI sources are supported and increase the brightness range. In Eco mode, brightness is reduced to 3,200 ANSI lumens with lower noise (27 dB(A)).

Connections and connectivity:

• 2× HDMI 1.4b – for notebook and presentation computer at the same time
• LAN (RJ-45) with Wake-on-LAN – remote switch-on via the network
• RS-232 – controllable via serial interface: on/off, input selection, brightness, volume, freeze, status monitoring
• Audio out (3.5 mm jack) – for connecting active speakers or a classroom sound system
• USB-A – power supply for connected receivers (5 V)
• VGA cable included

The integrated 16-watt mono speaker is sufficient for spontaneous presentations in small rooms. For demanding teaching or conference use, we also recommend an active speaker for even room coverage.

Installation and image sizes

The fixed throw ratio of 0.62:1 results in very short wall distances. The projector is typically mounted on the ceiling (inverted) or placed on a table close to the projection surface. Rear projection is also supported. The 115% offset means that the projected image lies completely above the optical axis when placed on a table. The following table shows calculated guide values for 4:3 images:

The calculated throw distances are based on the manufacturer's throw ratio and are intended as guide values. As measuring points (e.g. from the centre of the lens vs. the front of the housing) often vary between data sheets, calculations accurate to the centimetre cannot always be guaranteed.

For ceiling mounting, suitable ceiling mounts are available. For long cable runs from the signal source to the projector, correspondingly long HDMI cablesare recommended; passive HDMI cables up to approx. 5–7 m are reliable with Full HD signals. The M4 mounting point allows installation in standard ceiling mounts (max. 25 mm screw-in depth).

Security functions: password protection against unauthorised operation, keypad lock (only remote control active), automatic start when an HDMI signal is detected, direct power-on when mains power is applied.

Light source and running costs

The replacement lamp for the S1287 is available under part number UC.JY711.001. In typical school use (approx. 6 hours a day, ~180 school days/year), Eco mode gives a runtime of around 9 years before the first lamp change. If you would rather avoid lamp changes in the long term, we also offer laser models with a light source life of up to 30,000 hours – we are happy to advise you on the right model on request.

Which model is right for you?

The Acer S1287 is the short-throw model within the Acer business family and is aimed at installations with limited wall distance. If you prefer Full HD resolution or standard throw, you will find suitable alternatives in the P series.

Acer S1287 – ideal for schools, education and business short-throw use

• Classrooms with a projector position close to the wall and frequent teacher movement in front of the board
• Training rooms with compact room depth where standard-throw models would take up too much space
• Conference rooms with automated room control (direct power-on, Wake-on-LAN, RS-232)
• Digital signage installations with portrait mode or inverted ceiling mounting

Have you thought of everything?

• Ceiling mount – for permanent installation in the classroom or conference room
• HDMI cables – suitable lengths for ceiling mounting (passive reliable up to approx. 5–7 m)
• Screen – for short-throw projectors, we recommend a fixed-frame screen or a manual pull-down screen directly on the wall
• Active speakers – for even speech intelligibility in the classroom or training room

Conclusion: short-throw projector for education and conferences with solid operating features

The Acer S1287 addresses the most common installation challenge in classrooms and small conference rooms: short wall distance, shadow-free projection, full freedom of movement for the presenter. The fixed throw ratio of 0.62:1 makes complex room planning unnecessary. Direct power-on, Wake-on-LAN and RS-232 cover the usual automation requirements of IT departments and caretaker services. Portrait mode and 360° operation open up additional applications beyond the classic lecture. If you need 16:10 resolution for modern notebooks or higher light output, the Acer P series is a logical next step.
