The Digital Fix
March 2019

The Optoma offers a 720p image and is pretty short throw, meaning you can get a 6 foot wide (diagonal) screen from the middle of your average lounge. It's also astoundingly bright and sharp - the resolution difference between this and a full-fat 1080p unit is obvious, but soon forgotten when you're watching a film on something twice as big as the TV next to it. The same with games - you might be able to see the pixels, but that doesn't matter when you're ripping up foe-after-foe in a round of Fortnite.

The Optoma ML750ST is awesome value for money.

“The compact Optoma Beamer ML750ST displays a very big picture on the wall, even in smaller rooms. It's lightweight and due to it's compact size, it can fit almost anywhere, no matter how small the room!"

If you want a mini projector but don’t want to skimp on quality, then this Optoma projector is the best way to watch movies in HD right from a microSD card, USB stick or via the HDMI cable which allows you to connect this mini projector to your laptop or Blu-Ray player. It is a short throw projector, which means you’ll get a clear image on your chosen wall, and it can display up to a 100 inch image from just over a metre away. For business use, you can project your presentation wirelessly from your mobile phone, too.  

Evening Standard
April 2018

We were really impressed by this neat little projector from Optoma.

From the moment we plugged it in, we knew this projector was a winner. It took well under a minute to plug it into our laptop via an HDMI and project a high-quality image onto the wall.

There are higher-end models out there, but in our view, it’s the Optoma ML750ST that offers the best balance of price and performance. It’s smart, easy-to-use, and most importantly provides an exceptional quality of projection.

May 2017

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.

April 2017

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.

Geek News Central
March 2017

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.

Mobile Tech Talk
February 2017

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.”

December 2016

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.”

September 2016

“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.”

August 2016

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

Computer zive
August 2016

“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."

July 2016

“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.”

July 2016

"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."

July 2016

"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."

Trusted Reviews
May 2016

“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.”

T3 France
April 2016

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"

COM! Professional
February 2016

"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

ML750ST , I,ve run this nearly none stop since I got it over a year ago being disabled it helps me to see better and being able to take it with me helps, done lots hours with the xbox on this none stop for more the 48 hours at a time and its handled everything. light nd small what more could you want also my rooms arnt that big so the short fall on it helps a lot.
What a bright idea for road warriors.
James D. Feldman, CSP, Chicago, IL, September 2016.Purchased from Stampede
As a professional speaker I needed a small but powerful projector to put in my MacGiver carry on bag. This packs a lot of technology in a small footprint. It blows away anything else on the market. I am know as The Bright Idea Guy™ and this projector is one of the brightest ideas I have seen in a long time.
For anyone that presents to anyone about anything that uses slides, videos, movies, or other 'projectionable' materials this is a projector you have to consider if you are a road warrior.
super portable y liviano
Adriana Zangarini, Miami, May 2016.Purchased from B&H
Excelente video beam, super portable y liviano. Tenia el 750 y decidí cambiarlo al 750ST para poderlo proyectar mas cerca de la pared. Se los recomiendo sobre todo a los que tienen que estar moviéndose constantemente.
My review
Edison Pham, Toronto, April 2016.Purchased from AVS Unlimited
Bought ML750ST for my company and its a huge upgrade from the travel projectors we used to carry. Its so small, compact and most importantly - very light.

Its everything we needed in a portable projector.
Amazing for the size
Joe Russ, USA, March 2016.Purchased from Amazon.com
This is a brilliant projector for the road warrior. It's small, but very bright for the size and able to create a fairly large image in small spaces.

The color is much improved over the 500 lumens model and feels natural in all modes except the brightest.

The built in media player and file access features are awesome and allow you to share videos or photos without even needing a tablet, phone, or laptop.

My one downside is that at 700 lumens the project is not bright enough to view in ambient daylight conditions. But works awesome in any darker environment.

A very special purchase
T Alastair McLachlan, MILTON OF CAMPSIE, United Kingdom, February 2016.Purchased from Costco, Springburn, Glasgow
I have used Optima projectors in the past and got an unmissable offer for this one. I cannot believe how small it is, how easy to use, and what a clear picture it gives. I hope to use this on many happy occasions in then future. It is so easy to set up and use. Thanks for this.
