Portable multimedia projector based on DLP technology with built-in 2-channel audio system, 16:10 native aspect ratio and 1280x800 resolution. It has modest dimensions and low weight (0.75 kg). The main difference of this model is the built-in intelligent light sensor. This sensor allows the projector to automatically change the brightness and colour saturation of the image depending on the ambient light. This drastically reduces the number of adjustments that need to be made before the start of the presentation, while the image quality remains consistently high. The maximum brightness of the LED lamp is 800 lm, and the resource is 20,000 hours, which allows you not to think about the duration of the Acer K138ST projector at all. However, the life can be extended up to 30,000 hours by usin...g the economy low brightness mode. The short-focus optical unit allows you to work with throw distances from 0.4 to 1.7 m and projection diagonal sizes from 0.6 to 2.5 m. It is possible to correct vertical keystone distortion (up to 30 °). The projector has a high frame rate (120 Hz) and is capable of working with 3D video. To obtain a high-quality image, it is equipped with a digital HDMI interface and an analogue VGA D-sub input. Built-in two-channel audio can handle the task of voicing a small audience.
