The XGIMI Horizon 20 Pro 4K projector is currently on sale on Amazon for 1699 €, a reduction from its original price of 2070,11 €. This discount is part of the Prime Day Flash Sales, which occur on October 6 and 7, and are exclusive to Amazon Prime members. The projector is designed for use in rooms with ambient light, thanks to its brightness of 4100 lumens ISO. It uses an RGB laser light source, offers a 4K resolution of 3840 x 2160 pixels, and runs on the Google TV system. It is part of the Horizon 20 series, with the Pro model serving as a middle option between the standard Horizon 20 and the Max model, which has a higher brightness of 5700 lumens. The XGIMI Horizon 20 Pro 4K is ideal for users looking to project large images in their living rooms, with the ability to display images ranging from 40 to 300 inches. It includes lens shift and optical zoom, which allow for flexible placement, such as on a low table or at an angle. The projector supports advanced video formats like Dolby Vision, HDR10+, and IMAX Enhanced, and is suitable for gamers due to its 1 ms latency and support for display rates up to 240 Hz. According to some reviews, the projector's brightness is its main selling point, achieved through an RGB laser source with 30 laser diodes that reach up to 4100 lumens ISO. However, the High Power mode is criticized for being too noisy due to the fan and for producing a greenish tint. In a well-calibrated Film mode, the brightness is around 3000 lumens, with other measurements showing between 2850 to 2950 lumens. In Bright mode, it can reach up to 4561 lumens. The Google TV interface is sometimes considered unstable, with some users recommending an external device like an Apple TV for better performance. Despite this, the projector has received enthusiastic reviews, scoring 9/10 at Presse-Citron and 4.5/5 at Son-Vidéo, with praise for its sharpness, color accuracy, and sound quality. However, the device is described as bulky, and the fan can be noticeable when the brightness increases. Even with the discount, the price remains high, and potential buyers are advised to carefully consider their needs before purchasing.
