- Reviewed in the United States on January 12, 2014Style: 700 lumens/Standard ThrowVerified PurchaseThe Optoma ML750 700 lumen 3D portable LED projector is an amazing piece of technology. The first impression out of the box is how small it is and how light it is. The projector comes with a very nice travel zip-up bag with the Optoma logo on it, a small power supply that comes apart at the power box so it is a total of 2 cords. A universal in to VGA out with an audio in. Even if you don't use this to connect to a computer you can plug in universal and bring audio in. The last thing is a very nice controller which has all the functions that you can use on the machine. I also bought a Sunpak SPK620786 5-Inch Flex Leg Mini-Spider Tripod which fits it perfect and works very well to hold it up and change angles.
I connected via Macbook Pro retina through the HDMI port on the back. I changed input to HDMI and it matched my screen within 5 seconds. I first used it in my office which is very bright and I projected from about 10 ft back and I had an amazing, bright beautiful picture of my computer screen which is a stock Apple image with vibrant colors. I was amazed at how bright it is and how good the picture is. I then played a video from netflix to test the sound and the speakers are ok for a small group of people but not good enough for a good action movie in your house. I would just use the audio from your input device or from the universal cord with audio in. The keystone correction works very well but usually you don't need it, keystone is always a salesman pitch but when its on your wall you don't really care that it is a little bigger on the top than the bottom, trust me.
I looked for about 2 weeks for which projector I wanted. I am using this for office presentations in a large well lit conference room, home movies and demonstrations at different stores that we have in our company. The other projectors I looked at are the Optoma ML550, Qumi Q5, Aaxa P300, Aaxa LED showtime, Dell M110 and a couple of the brookstone models. The Qumi Q5, ML550 and the Dell M110 were the only ones that were kind of close to this in the way of picture quality and brightness. The ML550 is the same thing just 200 less lumens, the Dell M110 is very close in size where the Q5 is a little larger and more rectangle shaped. After looking at these and testing them the ML750 was the best in brightness and quality of picture.
This is one of the only projectors in this market that you can project a large picture in a room with bright lights and still have really good quality and brightness. I projected a powerpoint in our conference room with the 20 plus lights we have and I could read even the smallest print well. I tested this next to a standard light projector that was 2,500 lumen in our conference room and this has a better picture and looked brighter! That's the power of LED.
Overall this is in my opinion the best "pico" projector on the marker for its size, connections, and quality of display. You can't fit it in your pocket but it comes pretty close to. I would not waste my time with the smaller below 300 lumens on the market, you just don't get a bright enough picture. I have not tested the 3D but will test and amend this when I do.
I would recommend this to anyone who is in the market for a small, LED projector that looks amazing.
- Reviewed in the United States on December 19, 2014Style: 700 lumens/Standard ThrowVerified PurchaseI got this projector to provide entertainment for a recent deployment. It's awesome. I originally had a bit of buyer's remorse while I was waiting for it to come in the mail due to the fact that I didn't realize that the only audio out available was part of a composite cable. Honestly, I've never even used the built in speaker, but I knew it wasn't up to the task of providing the audio for movies, which is the only reason I bought this projector. I found a workaround for this by getting a bluetooth enabled soundbar and a bluetooth adapter for my laptop, and using an HDMI cable to provide the video source to the projector. This was the smallest, brightest, HDMI capable projector I could find on Amazon, and it works great. It's not cheap, but for a couple hundred dollars more than its closest competitors, it is much MUCH brighter. The image quality is at the level that every single person here that has seen is has commented on how amazing it is. I don't regret buying this projector at all, but if I had to do it again, I would have paid the extra money to get the model above this (ML1000P). It's a little bigger, but it has the power source inside rather than a big brick attached to the cable, plus it's brighter. When you combine the size of this projector with the power source, it's about the same size as the ML1000P. A previous reviewer made a great video comparing the two.
Besides that, I haven't noticed the fan making any noise at all, really. The focusing is a little finicky, too; when the center is sharply in focus, the top and bottom edges are a little blurry. Also, it does seem to need to be refocused about 10-15 minutes after start up. After that, it is good to go.
If I had to do it again, I would have gotten the ML1000P. If cost is an issue, then this is a great, small, portable, BRIGHT projector. If you can spare the extra money, get the upgraded model.

5.0 out of 5 stars Amazing little LED projector
Style: 700 lumens/Standard ThrowVerified PurchaseI'm very pleased with this little LED projector. I've put on 50hrs of use so far. It surpassed my expectations. The picture is clear, even on a simple white wall. The 700 lumen is great for playing videos in the basement or in a dark or dim lit room, even at a 90 inch display. Kids love it for watching movies. Works with the Xbox 360 using an HDMI cable and external speakers. Works well with the laptop using the provided special VGA / audio cable and display port to HDMI cable I purchased separately. Videos, pictures, PDF and Word documents work well with my USB stick. The remote is a little slow at navigating the menu or selecting a file when using the USB stick but not sure if it's because of my USB stick or the projector. The one watt speaker is a joke but I wasn't expecting it to be anything but. You want to avoid using the on board speaker and get yourself some computer speakers. Love the quick startup and shut down. You may want to also get a small tripod. I find that more times than not, I need to set the projector on top of a shoe box to get a little more height. Looking forward to many years of use.
UPDATE:
Almost 4 years later and it's still going strong. We get a lot of use, including taking it camping with us. Love this little projector. Perfect for the basement area. Would recommend to anyone looking for a small portable LED projector with many features.

4.0 out of 5 stars Small, but it has everything you need.
Style: 700 lumens/56" Distance for 80" ImageVerified PurchaseThe media could not be loaded.
I took this sample video in the afternoon.
I hope it has excellent durability.
Pro: Buy it if you live in a condo, suitable for a small space. It's modest with a High-quality image. It has an autofocus function.
Con: Bad built-in speaker. No integrated blue tooth connection, which means you have to buy a blue tooth transmitter. The autofocus function needs to be improved.

5.0 out of 5 stars Small and mighty.
Style: 700 lumens/56" Distance for 80" ImageVerified PurchaseLove this little guy. High resolution and short-throw. Quality of the image doesn't degrade as you expand. Could stand to be a bit brighter, but given the size you can't expect more. Light, compact and comes with a great little remote. Makes little or no noise and boots up quickly. Perfect for people who travel a lot and give presentations.

1.0 out of 5 stars HDMI doesn't connect with my Mac Book Pro
Style: 700 lumens/56" Distance for 80" ImageVerified PurchaseI purchased the projector a while ago, I was never able to connect with HDMI on either a MacBook Pro or my wife's MacBook Air. We tried 3 different HDMI cords with no success. We use it with the VGA connector. The projector works fine in small dark rooms which is why we bought it.

5.0 out of 5 stars Impressive projector
Style: 700 lumens/56" Distance for 80" ImageVerified PurchaseIt might not be full HD but, after 2 months of MLB.TV, blu rays, dvds,... ., it doesn't feel like a compromise:
- uniform image
- accurate, strong colours
- quiet
