The Optoma 4K400STX is a short-throw projector that uses DLP technology to display a native 4K UHD (3840x2160) resolution. It is rated for a brightness of 4000 ANSI lumens, which allows for use in rooms with some ambient light. The specified contrast ratio is 1,000,000:1, contributing to the definition between light and dark areas of an image. This model has a native 16:9 aspect ratio, compatible with standard widescreen content, and also supports a 4:3 ratio.

With a fixed 0.5:1 throw ratio, the projector is designed to produce large images from a short distance, making it suitable for smaller meeting rooms, classrooms, or home entertainment setups. It can project a screen size ranging from 36.4 to 300.5 inches. The unit supports High Dynamic Range technology, specifically the HDR10 and HLG formats, to enhance color and detail in compatible video content. For image alignment, it provides both horizontal and vertical keystone correction of up to ±40 degrees.

Connectivity options include two HDMI ports for connecting source devices and one USB Type-A port. For audio, the projector has a built-in 10-watt speaker and a 3.5 mm headphone output for connecting to an external sound system. The lamp-based light source is rated for a service life of up to 10,000 hours in its economic mode. The package includes an AC power cable and a remote control with batteries.
