Third-party reviews

What customers like about Optoma ML750

  • Ultra-compact and lightweight, making it highly portable
  • Impressive brightness (700 ANSI lumens) and color quality for its small size
  • Long-lasting LED light source (up to 20,000 hours) eliminates the need for expensive lamp replacements
  • Quick and easy setup, powering on and off almost instantly
  • Versatile connectivity options, including HDMI/MHL, USB, and a microSD card slot for PC-free presentations
  • Excellent value for its class, often cited as a more affordable alternative to full-sized projectors

What customers don't like about Optoma ML750

  • Internal speaker is very weak and quiet, often requiring external sound systems for a better experience
  • Lacks a zoom lens, which limits placement flexibility compared to standard projectors
  • Image can become fuzzy or lose sharpness around the edges, especially at larger screen sizes
  • Fan noise is noticeable in quiet environments, though typically less distracting at normal volumes
  • Lower native resolution (WXGA/720p) compared to modern 1080p or 4K standards
  • External power brick is relatively large and cumbersome compared to the tiny projector itself

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.
