The projector has a smart and compact design and was easy to set up.

I was able to play video straight from our camera using the micro SD slot. You can also plug your phone in and view a slideshow or any stored media, or you can buy a WiFi dongle (£30) to project wirelessly.

I was impressed with the resolution and surprised at how close  I could position the device to the wall and still achieve a large, crystal clear image. It projected well over bumps in the wall, and not having to position the device right at the back of the room is a great feature as it means you don’t need a huge room for an impressive display. The device is fairly lightweight (450g) so is easy to add to luggage.

The ST part of the projector’s name stands for ‘short throw’. If you’re not sure if this is a good thing or not, I reckon it is. You see, this means that it is able to deliver big images from a reduced distance away from the screen or surface you’re projecting on to.

Dark scenes contain much more realistic blacks than I was expecting for such a diminutive projector

This little ultra-portable projector certainly ticks a lot of boxes. It is easy to carry around, it’s bright and the colours are good.

As a business projector it does pretty much all you’ll need it to. Being able to run Office presentations without a PC is a bonus. Running it from a computer is decent too and the PC setting works as it should.

I’m pretty impressed by the ML750ST. I’m used to projectors about the size of the phone book and the ML750ST was able to do everything they can do and more. The ML750ST isn’t exactly an impulse buy as it’s priced at GB£529 and the USB WiFi dongle is an extra GB£30, but as business purchase, it makes a great deal of sense, especially with HDCast application for tablets and smartphones. I wouldn’t recommend it for a permanent installation in, say, a training room because a brighter projector would be more suitable, but for ad hoc presentations and portability, the ML750ST is a good choice.

MobileTechTalk awarded the ML750ST 9/10 for build quality and design, 8.5/10 for sound and value and 9.9/10 for projection quality - to give a score of 8.9/10 overall.

“the ML750ST is super bright, and runs a lot cooler than any other projector I’ve ever tried”

“The fact the ML750ST looks so good in a dark room, in a bright room, on the wall or even on a glossy whiteboard, probably the worst surface to project onto, shows you just how damn good this is.”

“Optoma’s name is synonymous with projectors for a reason. They’re bloody good at making them.”

Score: 9.43/10

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

“Its excellent benchmark performance was confirmed in our hands-on testing. We used the Optoma to view a variety of high-definition content in dark environments and those with ambient light, and image quality was phenomenal in both settings. Fine onscreen details were rendered in clear focus, and even on high brightness settings, color levels remained consistent and didn’t appear washed out.”

“This fabulous compact projector excels where space and time are at a premium. Using LED technology, it boots up in seconds and is so small it virtually fits in the palm of your hand.  Available with an optional wireless dongle, it can also display office documents without the need for a computer as a source.”

DDWorld gave the ML750ST a 90% rating and a DD's Recommended Award.  It concluded:

Nice sharp picture, good contrast and colour reproduction

LED life up to 20,000 hours and a decent operating characteristics

Very small and lightweight

Probably the best picture in the segment of small LED projectors

“The Optoma ML750ST belongs to the smallest LED projectors on the market offering high brightness and PC free use. The LED light source offers high life span. The high brightness of the projector and short throw ratio of 0.8  allows you to project onto a 147cm diagonal screen. We played many video formats directly from SD cards and the projector had no problem with any codecs. Displaying photos and presentation was also perfect. The high brightness and good connectivity make the ML750ST very handy."

“We reviewed four micro projectors but the ML750ST was the only one that made the cut. We were wowed by its performance, portability, and low cost.”

"The high-quality video and excellent color quality in Cinema mode also makes the ML750ST a top choice for home use. If you want a unit you can move easily to any room to set up as needed and still have an impressively high quality, 80" image even with some lights on, it's a perfect fit. And with it's 16.5 ms lag time, gamers will have only themselves to blame for slow reaction time."

"For traveling presenters doing sales presentations or educational tutoring to individuals or small groups, the ML750ST's ability to connect to a cell phone or read files from memory card or USB key means you don't have to bring anything heavier along with it."

"The enhanced setup and performance from the Optoma ML750ST’s high-quality, short-throw lens make this AC-powered mini projector an easy recommendation."

"What I didn’t expect was to find even one projector among four that I could comfortably recommend for even quasi-serious movie watching. No, the Optoma won’t go as bright or as black as my $4,000 reference projector. But it practically fits into the palm of my hand, and it threw a highly satisfying image for my critical eye at about one-seventh of the price."

"The ML750ST just wowed me with its combination of performance, portability, and low cost. It’s a great value."

“The ML750ST runs extremely quietly for such a portable projector, despite its impressive brightness.”

“The ML750ST’s input lag – the time it takes to render images after receiving their data – is outstanding; my measurements in the projector’s PC preset mode recorded barely 10ms. This is the lowest figure I've ever seen in a projector, and it means that you won’t be able to blame the ML750ST for any gaming fails.”

“The ML750ST is the best pocket-sized projector I’ve tested for all-round picture quality and its ability to switch effortlessly between business and domestic duties.”

Awarded 9/10

"Two big assets […] one short throw that allows you to show a big image from a minimum distance. The second, it‘s compactness."

"It handles colours and movement very well"

"The Optoma ML750ST shows what kind of impressive compact projectors can be developed based on LED-Technology.”

“Despite of its tiny size, it offers all the necessary and important connections. Among them a MHL supported HDMI, USB port and a Micro SD reader”

“Because of its tiny format, the ML750ST might get more attention in meetings than some PowerPoint presentations which are presented on it.”

Overall Grade: 2 = good
