Optoma ML750ST


The £480 ML750ST is an ultra portable (as in, it weighs less than half a kilogram and can comfortably be held in one hand) DLP projector with a short-throw lens that Optoma believes is suited to both business and home entertainment uses.

Optoma ML750ST Review


Whether you're a home user looking for an upscale mini projector or a business owner who need a compact and effective display tool, the Optoma ML750ST sits at the top of the heap. Its business focus creates some functionality gaps for home users, but...

The ML750ST has phenomenal image quality for a mini projector.

No Bluetooth audio support means you need hardwired speakers when presenting to large groups.

The Optoma ML750ST’s best-in-class performance and stellar construction make it an excellent centerpiece in your home theater or boardroom.

Amazing picture quality and brightness for the size. Focuses at very short distances. Really happy with this purchase.

I have mine on the ceiling projecting a 78" screen on to my wall and the image is fantastic, you can see the bumps on the wall but that was expected

Optoma ML750ST Short throw LED Projector


Very short throw as advertised, good quality (720p) image.

Image quality does degrade after around 60inch image diameter but that's to be expected. Fan is audible if used close by but it's not excessively loud.
