Dec 25, 2025, 06:16:02 UTC

During the highlight session of the Redmi K90 series flagship launch event, the REDMI Projector 4 Pro was officially unveiled. Positioned as "flagship experience at a sub-1000 yuan price point", it made a strong entry into the home projector market. This new product accurately addresses the core needs of young families and budget-conscious users, achieving comprehensive upgrades in four key dimensions: brightness, image quality, sound quality, and intelligent interaction. Furthermore, leveraging the advantages of in-depth linkage with the Xiaomi ecosystem, it redefines the value ceiling of smart projectors in the sub-1000 yuan segment. Currently, the REDMI Projector 4 Pro is fully available for sale with an initial subsidy price of only 1,439 yuan (original price 1,599 yuan), and can be purchased through all Xiaomi channels.

Textured Design, Seamlessly Integrating into Diverse Home Scenarios

The REDMI Projector 4 Pro adopts a minimalist design language, featuring a calm gray as the main color. The main body of the device is equipped with a delicate injection-molded fine leather texture finish, and the front face is adorned with skin-friendly fabric wrapping technology, providing a warm and soft touch. The metal passive plate on the back not only enhances the texture of the body but also resonates with the sound effect, making the audio experience more immersive. Its compact size supports multiple placement methods—whether front projection on the living room coffee table, side projection on the bedroom bedside table, or ceiling mounting—it can seamlessly integrate into different home styles, becoming a practical aesthetic item in the home environment.

Full-Scale Core Performance: Dual Breakthroughs in Brightness and Image Quality, Free from Dark Room Restraints

As a performance benchmark for projectors in the sub-1000 yuan range, the REDMI Projector 4 Pro has achieved comprehensive upgrades in core image quality parameters. The new product is equipped with a brand-new sealed optical engine, with an actual measured brightness of 600 CVIA lumens. This value has been officially tested and certified by CESI, a domestic authoritative institution, ensuring no false marking. It effectively solves the pain point of entry-level projectors—"failing to display clearly in light environments". Even in a lit living room or dimly lit bedroom, the image remains clear and transparent, with sharp text edges and complete detail presentation.
In terms of image quality, the product is equipped with a native 1080P physical resolution, rather than "pseudo-HD" achieved through dithering. It can accurately restore rich details in video images, whether watching high-definition movies, displaying office documents, or playing educational courseware, bringing a clear and delicate visual experience. At the same time, it adds MEMC motion compensation technology for the first time. Through intelligent frame interpolation algorithms, it effectively reduces jitter, blurring, and stuttering in fast-moving images such as sports events and action movies, making dynamic scenes smoother and more natural. With a user-friendly throw ratio of 1.25:1, it can project a 120-inch giant screen at a distance of 3 meters, allowing small spaces to easily create a private cinema. Moreover, it has obtained SGS low blue light certification, which can filter harmful blue light in the range of 415nm-455nm, reducing visual fatigue during long-term viewing and protecting the eye health of the whole family.

Powerful Sound Quality, Unlocking Diverse Fun with Dual Usage Modes

In terms of audio experience, the REDMI Projector 4 Pro has achieved leapfrog improvement. The new product is equipped with dual 8W high-power speakers, innovatively adding independent bass passive plates. Combined with a 500cc extra-large sound cavity and a digital power amplifier chip, it builds a three-dimensional surround sound field with a bass extension depth of up to 25Hz and clear and transparent treble. Whether playing movie sound effects or music tracks, it can bring a rich and powerful audio impact. This configuration, commonly used in mid-to-high-end projectors, allows users in the sub-1000 yuan range to enjoy a cinema-level audio experience.
More practically, the product supports a Bluetooth speaker mode. In the shutdown state, it can be connected to mobile phones, tablets, and other devices via Bluetooth to become a portable Bluetooth speaker. It can easily handle external music playback and audio book sharing, realizing the diverse value of "one device, two uses".

Upgraded Intelligent Interaction: 2-Second Non-Sensing Calibration, Ready to Use Out of the Box for Beginners

Addressing the pain point of "cumbersome debugging" of traditional projectors, the REDMI Projector 4 Pro is equipped with the latest generation of ToF laser sensing module, combined with powerful AI algorithms and a high-performance MT9660 chip, to achieve non-sensing auto-focus and non-sensing omnidirectional auto-calibration functions. There is no waiting time when turning on the device, and a square and clear image is presented instantly. If the device is moved during use, it can also automatically complete focusing and calibration without any interruption, ensuring an uninterrupted viewing experience.
Official data shows that its non-sensing auto-focus time is 28% shorter than that of the previous generation product, and the non-sensing auto-calibration speed is as fast as 2 seconds. At the same time, it supports image obstacle avoidance and intelligent screen alignment functions. It can automatically identify and accurately avoid obstacles such as wall switches and decorative paintings on the wall. If used with a projection screen, it can also automatically align with the edge of the screen. The response speed of obstacle avoidance and screen alignment is 23% faster than that of the previous generation, truly realizing a convenient experience of "ready to use out of the box". In terms of core configuration, the 2GB+32GB storage combination ensures smooth system operation, which can easily accommodate various audio-visual apps and local resources. The dual-band Wi-Fi ensures no delay or stuttering during screen casting and online viewing.

Xiaomi Ecosystem Linkage: Creating Personalized Smart Viewing Scenarios

As a Xiaomi ecosystem product, the REDMI Projector 4 Pro deeply supports the Xiaomi Surge Intelligent Connection function. Through the Mi Home App, users can customize the linkage logic with other smart devices. For example, after setting the "viewing mode", when the projector is turned on, the lights are automatically turned off and the curtains are automatically closed, instantly creating an immersive viewing atmosphere. The built-in Xiaoai Classmate voice assistant supports voice commands such as ordering video resources, adjusting volume, fast-forwarding and rewinding, without manual intervention throughout the process, making it easy for the elderly and children to use.
The system has a large number of built-in video resources, covering all categories such as movies, TV series, variety shows, sports events, and educational courseware, meeting the needs of users of all age groups. At the same time, it supports one-click screen casting function, allowing content from mobile phones, tablets, and computers to be quickly projected onto the giant screen, easily coping with both home audio-visual entertainment and temporary office presentations. In terms of interfaces, it is equipped with HDMI (ARC), USB 2.0, and 3.5mm headphone interfaces, which can connect to game consoles, U disks, soundbars, and other devices, providing strong expandability.

Value-for-Money Pricing + Reliable Guarantee, The Go-To Choice in the Sub-1000 Yuan Range

Positioned as "flagship experience at a sub-1000 yuan price point", the REDMI Projector 4 Pro integrates high-brightness image quality, powerful sound quality, intelligent interaction, and ecosystem linkage, completely resolving entry-level users' concerns about projectors such as "insufficient brightness, cumbersome debugging, and poor experience". Currently, the new product is fully available for sale with an initial subsidy price of only 1,439 yuan (original price 1,599 yuan), and can be purchased through all channels including Xiaomi Mall, JD.com, and Tmall. It also provides a 2-year warranty service, allowing users to buy with confidence and use at ease.

Whether it is young families pursuing cost-effectiveness, renters, or users in need of convenient office presentations and parent-child education, the REDMI Projector 4 Pro can bring an exceeding-expectation smart giant screen experience with its comprehensive performance, convenient operation, and affordable price, worthy of being called an "all-rounder" and the go-to choice in the sub-1000 yuan projector segment.
