Product Information

Full details

The Optoma ML1050ST+ is an ultra-compact, lightweight short-throw projector designed for mobile professionals, educators, and home entertainment enthusiasts who need a versatile display solution without the bulk. Its key benefit lies in the ability to project a massive 100-inch image from just over a meter away, combined with a built-in office viewer and auto-focus for lightning-fast setup. While highly portable and feature-rich, the primary caveat is the modest 1W integrated speaker, which may require external audio for larger rooms or immersive cinematic experiences.
