The Appotronics Laser Home Cinema Projector D30 projects images in 4K with cinema-quality sound. To ensure high levels of brightness when the size is small, it uses ALPD 3.0 laser display technology combined with an ultrashort focal lens. The device is sleek and elegant, with rounded edges ensuring that its look is not overly technical. The air vents are concealed behind a grille with a black oxide finish that contrasts with the polished exterior casing. This ensures the technical requirements for high volume ventilation are met while maintaining aesthetic appeal.
