Optoma 4K400STx Short Throw DLP 4K UHD 4000 ANSI lm Projector, White

The Optoma 4K400STx is a projector that uses DLP technology to produce a native 4K UHD (3840 x 2160) resolution. It has a brightness rating of 4000 ANSI lumens, which allows for clear image projection in rooms with some ambient light. The projector's 1,000,000:1 contrast ratio contributes to image depth by defining the difference between light and dark areas. It supports both 16:9 and 4:3 aspect ratios for compatibility with different source materials. The lamp-based light source is rated for up to 4,000 hours of use in standard mode and extends to 15,000 hours in economic mode.

A primary feature of this model is its short-throw design, indicated by a 0.5:1 throw ratio. This allows it to project a large image, from 36.4 to 300.5 inches, from a projection distance of 0.4 to 3.3 meters, making it suitable for smaller spaces. The projector supports both 3D and High Dynamic Range (HDR) content, providing additional visual options for compatible media. For setup flexibility, it includes both horizontal and vertical keystone correction of up to 40 degrees to help align the image geometry on the projection surface.

For connectivity, the device is equipped with two HDMI ports for high-definition sources and a USB 2.0 Type-A port for service or power. An integrated 10-watt speaker provides basic audio output, and a dedicated headphone jack is available for connecting to external audio systems. The projector's physical dimensions are 315 mm in width, 270 mm in depth, and 118 mm in height, with a total weight of 3.98 kg. The white chassis is designed for front, tabletop, or ceiling placement to accommodate various installation scenarios.
