Xiaomi has introduced the Redmi Projector 4 Pro in China as the successor to last year’s Redmi Projector 3 Pro. It is priced at 1,499 yuan (around $210) and is now available for purchase on JD.com.
Redmi Projector 4 Pro Specifications
The projector supports native 1080P resolution and delivers 600 CVIA lumens of brightness. It uses a newly designed sealed optical engine that improves brightness output, blocks dust intrusion, and operates with noise levels as low as 29dB.
The Redmi Projector 4 Pro runs on the MediaTek MT9660 processor with 2GB of RAM and 32GB of eMMC storage. It operates on Xiaomi’s HyperOS Connect platform, offering seamless integration with the Xiaomi smart ecosystem. This allows users to automate smart home actions like dimming the lights or closing the curtains when the projector is powered on.
Xiaomi has equipped the device with a projection ratio of 1.25:1, allowing it to project screen sizes from 45 to 120 inches. It also features MEMC motion compensation to reduce stutter and trailing during fast-moving content. The projector has received SGS low blue light certification and can filter blue light in the 415nm to 455nm range.
The projector uses a ToF laser module and an HD camera, along with AI algorithms, to enable automatic focusing and omnidirectional keystone correction. It can also detect obstacles on the wall and automatically align the image to fit within a projection screen frame. These adjustments typically complete within two seconds.
For audio, the Redmi Projector 4 Pro includes dual 8W full-range speakers with passive bass radiators and a 500cc sound cavity. The setup supports frequency response down to 25Hz and is designed to deliver immersive sound without the need for external speakers. When the projector is not in use, it can function as a Bluetooth speaker.
For connectivity, it includes HDMI (ARC), USB 2.0, and a 3.5mm headphone jack. It also supports dual-band Wi-Fi (2.4GHz and 5GHz) and Bluetooth 5.1. The projector weighs 3kg and consumes up to 150W of power.
The design features a soft grey finish with a fabric-covered front panel. The projector supports wireless casting from smartphones, tablets, and laptops.
