The Optoma W371 projector uses DLP technology and has a native WXGA resolution of 1280 × 800 pixels. Its light output of 3800 ANSI lumens and 16:10 aspect ratio ensure clear presentations in meeting rooms and classrooms, even without complete darkness. The lamp light source has a lifespan of up to 10000 hours in eco mode, which, along with its energy-saving features, reduces the overall running costs. A high contrast ratio of 25000:1 renders sharp details in both dark and light areas of images and text. Thanks to its short throw distance, this DLP projector can create a large screen size even in smaller spaces.
The projector uses DLP display technology to project in a native WXGA resolution of 1280 × 800 pixels with a 16:10 aspect ratio. A light output of 3800 ANSI lumens supports projection in lit rooms without loss of legibility. The high dynamic contrast ratio of 25000:1 adds depth to the image, rendering bright whites and rich blacks, which improves the readability of texts and graphs. The projector's colour performance covers the sRGB standard for a true-to-life picture. The projected image screen size can be adjusted from 32.28” to 299.61”.
The light source is a lamp with a lifespan of 6000 hours in standard mode. The projector offers several power-saving modes that extend lamp life and reduce energy consumption. In Eco mode, the lifespan increases to 10000 hours, and in Eco+ mode, it reaches up to 15000 hours. The Eco AV mute function temporarily mutes the image and reduces consumption by up to 70%. The operating noise of the fan is in the quiet range of 27 to 29dB. The projector's maximum power consumption is 225W.
This WXGA projector uses short-throw optics to project a large image from a distance of 1 to 12 metres. This simplifies its placement in smaller spaces. Vertical keystone correction of ±40° digitally adjusts the image geometry if the projector is not positioned perpendicular to the projection surface. The manual 1.1× zoom adds flexibility for the final image size adjustment. The projector can be installed on the ceiling or placed on a table.
An HDMI 1.4a input, a VGA port and a composite video input are available for connecting source devices. Connectivity is complemented by an audio input and output via a 3.5mm jack. The USB-A port with a 1A output powers external devices such as streaming dongles. An RS232 port is included for integration into control systems.
