Image and display technology
The DLP display technology renders an image in native 1280 × 800 WXGA resolution with a 16:10 aspect ratio. Its light output of 535 ANSI lumens is designed for use in environments with controlled lighting, such as darkened meeting rooms. The high contrast ratio of 20000:1 contributes to deep blacks and clear details in both dark and light parts of the image. The projected image size can be adjusted from 127cm to 254cm screen sizely, which corresponds to 50" to 100".
Short-throw projection and installation
The short-throw lens projects a large image even from up close. From a distance of just 0.86 metres, it creates an image with a screen size of 1.27 metres (50"). Automatic vertical keystone correction within a range of ±40° simplifies image setup when the projector is placed off-axis to the screen. The projector also supports 360° projection and portrait mode, expanding its use for creative installations. The lens zoom is fixed.
PC-free presentations and gaming performance
The built-in media player and native Office Viewer process files directly from a microSD card or USB storage, which eliminates the need to connect a laptop for presentations. It supports common document, image, and video formats. The projector supports 3D-ready content and, for gamers, has a low input latency of 16ms, which reduces the delay between the input signal and its display. An integrated 2W speaker provides basic sound.
Connectivity
An HDMI 1.4b port is used for connecting external signal sources. The interface is complemented by a microSD card reader and a USB-A port for media playback. A 3.5mm audio output is available for connecting to an external sound system. Wireless content sharing is an optional feature when the EZC-USB module is connected, which works with the EZCast Pro and Creative Cast apps.
