Overview
The Acer X1129 is a compact DLP projector for a wide range of uses: presentations in offices and training rooms, teaching and home cinema. With 4,800 ANSI lumens, it offers ample brightness for bright environments. SVGA resolution (800 × 600 pixels) and the 4:3 aspect ratio make it ideal for classic presentation content and older signal sources. Thanks to flexible mounting options and practical features such as lens shift and automatic keystone correction, the projector adapts to a wide variety of installation situations.
Benefits and special features
- Top-loading lamp replacement – easy to swap even when ceiling-mounted, without removing the projector
- Acer LumiSense – automatically adjusts brightness and colour saturation to the ambient light
- Wall-Color Compensation – optimum picture quality on coloured surfaces (boards, wallpaper) with 5 preset wall colours
- 3D-Ready with HDMI 1.4a – 3D content from Blu-ray players and games consoles without an additional PC
- Flexible installation – rear/front projection, ceiling mounting, 360° rotation and up to 25° tilt
- BluelightShield – reduces blue light by up to 30 % to protect your eyes
- AC Power On – starts automatically when the power supply is switched on
Picture and sound quality
The Acer X1129 uses DLP technology with a 0.55" BrilliantColor chip (DarkChip 3 DMD) and achieves 4,800 ANSI lumens in standard mode and 3,840 ANSI lumens in ECO mode. The 20,000:1 contrast ratio provides good depth. Acer ColorBoost 3D technology combines optimised image processing with a 6-segment colour wheel and ensures true-to-life colours throughout the product's life cycle – backed by the 5-year warranty on the DLP chip.
Audio is provided by an integrated 3-watt mono speaker. For larger rooms or higher volume requirements, we recommend an external amplifier via the audio output (3.5 mm jack).
Connections: 2× HDMI 1.4a (with HDCP), 1× analogue VGA (15-pin D-Sub), 1× composite video (RCA), 1× audio input (3.5 mm jack), 1× USB Type A (5 V DC output for external devices), 1× audio output (3.5 mm jack), 1× D-Sub output (monitor loop-through), 1× RS232 for system control. The USB output can power smart sticks or other USB devices.
Mounting and installation
The Acer X1129 supports flexible installation options: table placement, ceiling mounting with rear or front projection, 360° rotation and up to 25° tilt. The top-loading lamp design allows the lamp to be replaced even when mounted overhead, without removing the unit.
In the box: Projector, VGA cable (1.80 m), power cable (Euro plug, IEC 320 C13), lens cap, carry bag, quick start guide (printed), PIN security card.
Installation note: the lens offset (image shift) is 120 % vertically, allowing flexible positioning of the projector relative to the screen. For ceiling mounting, we recommend allowing approx. 7–12 cm for power and signal cables in addition to the housing depth (105 mm).
| Image size (diagonal) | Image width (approx.) | Throw distance |
|---|---|---|
| 80 inches | 163 cm | 3.20 m – 3.51 m |
| 100 inches | 204 cm | 4.00 m – 4.39 m |
| 120 inches | 245 cm | 4.80 m – 5.27 m |
The throw distances shown are calculated guide values based on the throw ratio in the data sheet. The reference point for the measurement – lens centre or front edge of the housing – is not always clearly stated in the manufacturer's specifications. For planning accurate to the centimetre, we recommend checking the detailed dimensional drawings in the manufacturer's manual or contacting our specialist advisors – we will be happy to help you plan the precise installation.
