Optoma HD31UST Ultra Short Throw DLP Full HD 3400 ANSI lm Projector, White

The Optoma HD31UST is an ultra-short-throw projector that utilizes DLP technology for image projection. It delivers a native Full HD resolution of 1920 x 1080 pixels with a brightness level of 3400 ANSI lumens. Its native 16:9 aspect ratio is standard for widescreen content found in home cinema and gaming applications. This model is designed for tabletop or desktop placement in environments where a large image is required but projection distance is limited.

A primary feature of this projector is its 0.25:1 throw ratio, which enables it to produce an image between 80 and 100 inches from a distance of 0.45 to 0.56 meters. The projected image is supported by a 28,000:1 typical contrast ratio. For setup and alignment, the unit includes manual focus control along with both vertical and horizontal keystone correction of up to 40 degrees, which helps correct trapezoidal distortion when the projector is not perfectly centered.

For connectivity, the device is equipped with two HDMI 1.4a ports, two USB Type-A ports, and two VGA inputs. An integrated 16W speaker provides onboard audio, and the projector supports 3D content playback from compatible sources. The unit also includes an Ethernet LAN port for wired network connection. The housing is white, and it operates using a standard AC power source, with a typical power consumption of 200 watts during use.
