Acer X1228H
The Acer X1228H projector uses DLP imaging technology to project in a native resolution of 1024 × 768 XGA. The DLP projector is designed for use in environments with ambient light, which is reflected in the high brightness of the lamp source, rated at 4800 ANSI lumens in standard mode. This means the image is clearly visible even in non-blacked-out meeting rooms or classrooms. As a short-throw projector, it offers flexible installation options even in smaller spaces. The Acer Essential projector is equipped with technologies to optimise colour and protect your eyesight, making it a suitable tool for long-term professional use. The 20000:1 contrast ratio helps to render detail in both dark and light parts of the scene. The integrated 3W speaker provides basic sound, which is sufficient for smaller rooms.

- Supports 4:3 and 16:9 aspect ratios
- Offers a 20000:1 contrast ratio for sharp details
- Uses DLP technology for display
- Fan noise reaches 32dB
- Offers a wide range of inputs including HDMI, VGA, composite video, USB, and audio in/out
- Includes a built-in 3W speaker
- Supports DLP 3D Ready technology for three-dimensional content
Image properties and technology
The DLP imaging chip operates with a native aspect ratio of 4:3 and also supports the 16:9 widescreen format. A 20000:1 contrast ratio delivers clear separation between light and dark shades. Consistent and vibrant colour reproduction is supported by Acer colourBoost3D and colourSafe II technologies, which prevent colour degradation over time. Acer LumiSense automatically adjusts brightness and saturation according to the content being projected. For eye protection during extended viewing, BlueLightShield mode reduces blue light emissions. You can adjust the image size from 58.4cm (23") up to 762cm (300"). The projector also supports displaying three-dimensional content thanks to DLP 3D Ready technology.
Projection and installation
The projector is designed for a short throw distance with a throw ratio of 1.94 to 2.16. This ratio means that from a distance of two metres, it creates an image with a 51" screen size. The projection distance ranges from 1m to 11.8m. You can zoom in on the image using the 1.1× manual optical zoom, which provides basic flexibility for final screen size adjustments without needing to move the projector. Installation options include front, rear, ceiling, and rear ceiling projection, covering most common scenarios in offices and homes.
Light source and operation
The light source is a 220W lamp with a lifespan of 6000 hours in normal mode. Activating the power-saving ECO mode extends the lifespan to up to 10000 hours. In this mode, power consumption also drops from 275W to 205W and luminance is reduced to 3600 ANSI lumens, which is still sufficient for less-lit spaces. The fan noise in standard mode is 32dB, which is equivalent to a quiet conversation and is not disruptive during a presentation. In standby mode, power consumption is only 0.5W.
Connectivity
For connecting source devices, the projector is equipped with a set of digital and analogue ports. The core is an HDMI interface for modern laptops and players. For older equipment, the projector offers a VGA input, VGA output (D-SUB), and a composite video input (RCA). Audio connectivity includes a 3.5mm audio input and output for external speakers. The projector is also equipped with an RS232 port for control and a USB port for service purposes.

Native resolution vs. maximum resolution
Native resolution determines the actual number of physical pixels on the projector's imaging chip and defines the real sharpness of the image, whereas maximum resolution only indicates the highest signal the projector can accept and convert (downscale) to its native resolution. For a high-quality image, it is always crucial to look at the native resolution.Specifications
