Xiaomi Mijia 1S 4K Cinema UST Projector is a premium ultra-short-throw (UST) laser projector designed to bring a true cinema experience into the living room. Combining 4K resolution, ALPD laser technology, HDR support, and a projection size of up to 150 inches, the Mijia 1S offers impressive performance while requiring only a few inches of space from the wall.
Ultra-Short Throw Design
One of the standout features of the Xiaomi Mijia 1S is its ultra-short-throw projection system. Unlike traditional projectors that need to be mounted several meters away from the screen, the Mijia 1S can project a massive 100-inch image from approximately 24 cm (9.4 inches) away from the wall. With a throw ratio of just 0.23:1, users can enjoy screen sizes ranging from 80 to 150 inches while keeping the projector neatly positioned on a TV cabinet.

True 4K Resolution with Laser Projection
The projector features a native 4K resolution of 3840 × 2160 pixels, delivering exceptional detail and clarity for movies, sports, gaming, and streaming content. Powered by ALPD 3.0 laser display technology, the Mijia 1S produces bright and vivid images while maintaining excellent color accuracy and long-term reliability. Xiaomi rates the laser light source for up to 25,000 hours of operation, providing years of maintenance-free entertainment.
Brightness and Contrast Performance
With a brightness rating of 2,000 ANSI lumens, the Mijia 1S performs well in dimly lit and moderately bright rooms. The projector also features a 3,000:1 contrast ratio, helping deliver deeper blacks and improved shadow detail. While dedicated home theater environments will unlock its full potential, everyday viewing remains enjoyable even without complete light control.

HDR10 and MEMC Technology
To enhance image quality further, Xiaomi includes HDR10 support, which improves dynamic range and helps reveal more detail in both bright and dark scenes. The projector also incorporates MEMC (Motion Estimation and Motion Compensation) technology, reducing motion blur and improving smoothness during fast-moving sports broadcasts and action-packed films.
Immersive Audio Experience
The Mijia 1S is equipped with a built-in speaker system featuring multiple drivers for full-range and high-frequency sound reproduction. Bluetooth audio support allows the projector to connect with external speakers or soundbars, while USB and digital audio outputs provide additional flexibility for home theater setups.
Smart Features and Connectivity
Running on Xiaomi’s MIUI TV platform, the projector offers a smart TV-like experience with wireless connectivity and multimedia playback capabilities. The device supports dual-band Wi-Fi and Bluetooth 4.0 and includes a variety of physical ports such as HDMI, USB, LAN, SPDIF, AV input, and audio output. Users can also connect external streaming devices to access services such as Netflix and YouTube.
