Introducing the Salange Mini Projector YG300: Perfect for those relaxed movie nights at home. Crafted for personal entertainment, this LED projector supports up to 1080P video, ensuring you enjoy your favorite movies and shows in decent clarity. While the physical resolution stands at 320x240, it's best suited for videos rather than detailed presentations or business PPTs. Note: It does not support Dolby audio or MKV formats; adjustments might be required for optimum audio experience.
