Acer X1128H DLP 3D SVGA Projector - 4800 Lumens, 20000:1
The Acer X1128H DLP 3D SVGA Projector is designed for presenters and educators who need reliable, bright images in well-lit, medium-sized rooms. With 4,800 lumens of brightness and a 20,000:1 contrast ratio, it produces clear, vivid visuals without needing to dim the lights. Acer LumiSense™, ColorBoost3D™, and ColorSafe II work together to keep colours accurate and consistent throughout the lamp's life.
Why this product
4,800 lumens for well-lit rooms
At 4,800 ANSI lumens in Standard mode, it delivers clearly visible images even in rooms with significant ambient light, making it practical for daytime meetings and classrooms.
Long lamp life in ECO mode
Switching to ECO mode extends lamp life to up to 10,000 hours while reducing brightness to 3,600 ANSI lumens and cutting power draw to 205 W.
Accurate colour with ColorSafe II
ColorSafe II actively manages dynamic RGB levels to prevent colour decay over the lamp's lifespan, so images stay true to the original source.
Flexible image sizing from 23" to 300"
The 1.1x manual zoom and a throw ratio of 1.94 to 2.16 give enough flexibility to fill screens of very different sizes from a typical throw distance.
Four projection orientations
It supports Front, Rear, Ceiling, and Rear Ceiling modes, and is ceiling-mountable, making it straightforward to install in fixed or temporary setups.
BlueLightShield™ reduces eye strain
Acer BlueLightShield™ filters unnecessary blue light output, which is useful in environments where the projector is in extended daily use.

- Connects to laptops and desktops via VGA (D-sub) input — one port included.
- Accepts composite video (RCA) input, so older video sources such as DVD players can be connected directly.
- Audio input and output via 3.5 mm mini jack allows pass-through to external speakers or direct audio from a source device.
- VGA output (D-sub) lets you loop the signal to a second display or monitor simultaneously.
- Ceiling-mountable with support for all four projection orientations, compatible with standard ceiling-mount installations.
- No HDMI port is present, so devices that output only HDMI will require an adapter not included in the box.
Best for
- Presenters in well-lit meeting rooms who need 4,800 lumens of brightness to compete with ambient light without closing blinds.
- Educators and trainers who use the projector daily and benefit from up to 10,000 hours of lamp life in ECO mode.
- Installations needing flexible screen sizes, as it can project images from 23" up to 300" with manual zoom adjustment.
- Fixed-room installations where ceiling mounting is preferred and all four projection orientations are needed.
- Buyers with legacy equipment who rely on VGA or composite video connections from older computers and AV sources.
Trade-offs
- Users who need HDMI connectivity — no HDMI port is built in, so modern source devices will require a separate adapter.
- Home cinema use requiring high native resolution — the native resolution is 800 x 600 (SVGA), which is lower than the HD or Full HD expected for film viewing.
- Ultra-portable use — at 2.8 kg and 313 × 240 × 113.7 mm, it is not designed as a compact carry-around projector.
- Large-venue or auditorium use where a single unit is expected to fill a very large screen — the throw ratio and zoom range are optimised for medium-sized rooms.
