Product Overview
The ML750ST boosts an impressive 700 ANSI lumens, 20,000:1 contrast ratio with razor sharp focus, auto keystone and Rec709 color accuracy. The Optoma ML750ST will ensure that your presentations have a larger impact than ever.
Designed for traveling professionals and power-users the palm-sized Optoma ML750ST weighs less than one pound and features an integrated HDCast Pro device mirroring and multimedia playback. This features allows mirroring of Android, iOS, and Windows devices, presentation viewing and multimedia playback of music, pictures, and videos. LED light source is rated to last over 20,000 hours greatly reducing the need to buy or replace the LED lamp.
Short throw
With a short throw lens, you can project an impressive 100” image from just over a metre away. This allows you to place the projector closer to the wall, reducing shadows so you can present with ease.
LED technology
Optoma LED projectors use individual red, green and blue LED modules to create the projected image without the need for a color wheel.
LED illumination provides consistent brightness and color performance with increased efficiency to maintain its out-of-the-box image quality. And the extraordinary life of LEDs (up to 20,000 hours) will ensure it stays clear and bright.
In many situations the perceived brightness of LED projectors can be up to twice the brightness of an equivalent lamp-based projector. LED brightness* specifications allow for a better comparison against lamp-based projectors, which do not take advantage of the enhanced brightness perception the Helmholtz-Kohlrausch (HK) effect creates.
Bright, vibrant images - Rec709
Perfect for business presentations, watching movies or displaying graphics, the LED powered ML750ST delivers a wide color gamut, superior color saturation and outstanding brightness to produce intense yet accurate colors, achieving the Rec709 standard.

LED auto calibration
This tiny projector has a built in sensor that auto calibrates the LEDs everytime the projector is switched on. This provides you with consistent color performance and maintains the projectors out-of-the-box image quality throughout its lifetime and saving you from costly calibrations.
MHL
Turn your projector into a smart display by connecting your smartphone or tablet with a single cable using MHL*; now you can view presentations and documents, stream videos and share photos on the big screen. You can even use MHL to connect and power the HDCast Pro (sold separately).
*Connection to some devices may require additional cables and adapters, available separately.

360 projection
Images can be projected over a full 360° range along the vertical axis, including reproduction on a ceiling or floor.
HDCast Pro - wireless presenting (optional extra)

You can even set the projector to turn off after a set period of time using the ‘sleep timer’ function.
