Product Description

Optoma ML750ST Short Throw LED Projector

Short throw

With a short throw lens, you can project a striking 100" image from a little over a metre away. This lets you to put 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 colour wheel. LED illumination provides consistent brightness and colour 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 circumstances 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

Ideal for business presentations, watching movies or displaying graphics, the LED powered ML750ST delivers a wide colour gamut, superior colour saturation and outstanding brightness to produce intense yet accurate colours, achieving the Rec709 standard.


LED auto calibration

This small projector has a built in sensor that auto calibrates the LEDs every time the projector is switched on. This provides you with reliable colour performance and maintains the projectors out-of-the-box image quality throughout its lifetime and saving you from costly calibrations.


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. *Connection to some devices may require additional cables and adapters, available separately.


360° projection

Images can be projected vertically over a full 360° range, plus reproduction onto a ceiling or floor.

HDCast Pro - wireless presenting (optional extra)

Present wirelessly from your mobile device or laptop using the optional wireless USB adapter and free HDCast Pro app. Available on Android, iOS, Windows and Mac the HDCast Pro app gives you the choice to wirelessly stream videos, photos, audio and documents. The App will allow you annotate over files, view webpages and use the camera on your device as a document camera for a more collaborative experience.


Digital signage

Digital signage applications are ideal as the projector can be mounted in virtually any orientation and it can automatically play video files or a photo slideshow directly from a microSD card as soon as the projector is switched on. You can even set the projector to turn off after a set period of time using the 'sleep timer' function.
