Xiaomi Redmi Projector 3 Pro

Manufacturer: Xiaomi

The Xiaomi Redmi Projector 3 Pro is a full-featured home projector that combines a sharp 1080p output resolution with a broad set of smart connectivity options, making it a well-rounded option for everyday viewing. It runs a built-in smart TV platform and supports a dedicated smartphone app, giving users flexible ways to access and control their content without relying solely on external devices.

On the connectivity side, the projector offers two HDMI ports alongside a single USB port, and it covers all major wireless streaming protocols including AirPlay, Chromecast, and Miracast. Bluetooth and Wi-Fi are both built in, while the audio system consists of stereo speakers rated at 2 x 6W, complemented by a 3.5 mm headphone jack and a sleep timer for added convenience. Maximum projection size reaches 120″, and audible noise in eco mode is rated at 26 dB.

Pros
  • Supports AirPlay, Chromecast, and Miracast simultaneously, covering a wide range of wireless streaming options without extra hardware
  • Built-in smart TV platform removes the need for an external streaming device
  • Two HDMI ports allow multiple source devices to stay connected at the same time
  • Stereo speakers with 2 x 6W output provide a self-contained audio setup without requiring external speakers
  • A 3.5 mm headphone jack enables private listening directly from the projector
  • Eco mode operates at 26 dB, keeping fan noise at a low level during quieter viewing sessions
Cons
  • No RJ45 port means a wired Ethernet connection is not possible
  • Lacks a VGA or DVI connector, limiting compatibility with older display sources
  • Only one USB port restricts the number of USB devices that can be connected simultaneously
  • Does not include an S/PDIF output, which limits options for connecting to certain external audio systems
  • No laser light source, which typically affects long-term lamp maintenance compared to laser-based projectors
Who is this for?

This projector is a good fit for users who want a self-contained home cinema setup without relying on external streaming devices, thanks to its built-in smart TV platform and support for AirPlay, Chromecast, and Miracast. The 1080p resolution and up to 120″ projection size make it well-suited to dedicated living room or bedroom viewing environments where a large screen experience is the priority. Users who prefer quiet operation will also appreciate the 26 dB eco mode noise level, and those with multiple HDMI sources — such as a games console and a media player — will benefit from having two HDMI ports available simultaneously.

Who is this NOT for?

Users who require a wired network connection will find this projector limiting, as it has no RJ45 port, making it dependent entirely on Wi-Fi for network access. It is also not well-suited to environments that rely on legacy display interfaces, since there is no VGA or DVI output to accommodate older computers or presentation equipment. Additionally, users who want to route audio through a dedicated home theatre receiver via a digital optical connection will be restricted, as the projector does not include an S/PDIF output.
