Verdict

The Xiaomi Redmi Projector 4 Pro is a native 1080p Full HD projector featuring an upgraded brightness of 600 CVIA lumens and a sealed optical engine that prevents dust buildup for a longer lifespan. Driven by a MediaTek MT9660 chipset with 2GB of RAM and 32GB of storage, it offers smooth performance and integrates deeply with the Xiaomi HyperOS Connect ecosystem for smart home control. Key advantages include its advanced ToF laser module for near-instant 2-second autofocus and omnidirectional keystone correction, MEMC motion smoothing for fluid action scenes, and an impressive audio setup with dual 8W speakers and passive bass radiators. However, its primary drawbacks are the lack of a standardized ANSI lumen rating, making real-world brightness comparisons difficult, and its limited availability outside of the Chinese market.

What customers dislike about Xiaomi Redmi Projector 4 Pro?

  • Significant software limitations for international users due to the integrated Chinese smart system, which can make casting global apps like YouTube or Netflix difficult.
  • Lack of standardized brightness ratings, as Xiaomi uses 'CVIA lumens' instead of internationally recognised ANSI or ISO standards.
  • Durability concerns typical of single-panel LCD 'flashlight' projectors, which may be prone to panel degradation over time.
  • Limited physical connectivity options, including only a single HDMI (ARC) port and one USB 2.0 port.
