The YG391 2025 is a Laser-LCD projector by Meer, whose specifications list 400 ANSI lumens, a contrast of 20000:1 and a HDTV 1920 x 1080 resolution. The manufacturer specifies a durability of 25000 hours for the LED light source. With four hours of daily operation, this corresponds to a period of 17.1 years. Looking at practical performance, up to 203 cm can be illuminated with 400 ANSI lumens in dark environments. Once daylight is in the room, the image should ideally be no wider than 135 cm. Regarding signal processing, the model is compatible with incoming 1080P content. An additional 360° projection capability allows the device to be oriented at almost any angle. For wireless audio output, the projector also supports Bluetooth, making it easy to quickly connect external soundbars. Thanks to support for Miracast and Airplay, screen content can also be cast wirelessly from a smartphone, tablet, or PC to the screen.
