The Xiaomi Redmi Projector 4 has been revealed in China. Arriving as an upgrade on the 2024 model, its light source is said to offer 38% more brightness compared to its predecessor. Other features include a ToF sensor for automatic focus, dual integrated speakers and a range of ports including HDMI (ARC).

Xiaomi has launched the Redmi Projector 4 in China. It arrives as a cheaper alternative to the Redmi Projector 4 Pro. Plus, it offers various upgrades over the last generation model, the Redmi Projector 3.

The Xiaomi Redmi Projector 4 is a 1080p model with a 1,500:1 contrast ratio, like its predecessor. It can throw images up to 120 inches wide with a 1.2:1 throw ratio. However, the new version is said to be 38% brighter, with the LED light source offering up to 360 CVIA lumens brightness. It is worth noting that CVIA is not an internationally recognised standard for brightness measurements.

Another upgrade found on the Redmi Projector 4 is an MEMC motion smoothing feature. An integrated time of flight (ToF) sensor brings automatic focus, and you can also perfect the image with a keystone correction tool. On top of this, there are two integrated 5W speakers, ports like HDMI (ARC), USB 2 and an audio jack, and support for Wi-Fi and Bluetooth 5.1. This projector is compatible with Xiaomi HyperOS Connect, with users able to remotely control the device via the brand’s app or using voice commands. Available in a metallic beige color, the product measures 151.4 x 125.0 x 204.8 mm (~6.0 x 4.9 x 8.1 inches).

In China, Xiaomi sells the Redmi Projector 4 for CNY 1,399 (~$196). It is unclear whether or not this model will make its way to other markets like Europe, where the company has yet to release its Redmi projectors. However, it sells other models like the Xiaomi Smart Projector L1 Pro (curr. €288.50 at Amazon DE).
