Verdict

The Optoma ML750 is an ultra-portable LED projector featuring WXGA (1280 x 800) native resolution and 700 ANSI lumens of brightness. Weighing just 380g and measuring 105 x 106 x 39mm, it is designed for high mobility and palm-sized convenience. Key technical highlights include a 10,000:1 contrast ratio, a lamp-free LED light source with a 20,000-hour lifespan, and versatile connectivity via HDMI/MHL, USB, and microSD for PC-free presentations. Its main advantages are its exceptional portability, instant power on/off capabilities, and integrated media player with a native office viewer. However, notable drawbacks include its modest 1W mono speaker, which can be underpowered for larger rooms, and reports of occasional image fuzziness near the edges of the screen.
