Our Optoma ML750ST Review

Size matters when churches, individuals, or businesses are looking for a durable and portable pico projector.

These smaller pieces of equipment are just as reliable and powerful as traditional projectors, but make it much easier to watch a movie or a presentation in a smaller room without a large setup.

Thanks to the design of short throw projectors and the fact that they don’t require very much space for operation, they are a great choice for small rooms.

The Optoma ML750ST is one of the best short throw projectors on the market and has the added bonus of being wireless.

What Is the Optoma ML750ST?

The Optoma ML750ST is a very small short throw LED projector. Its ultra-compact size means that it weighs less than one pound, which is very impressive for this type of equipment.

With a high contrast ratio of 10,000:1 and impressive image brightness and resolution, it is a very versatile piece of equipment.

First released three years ago, the Optoma ML750ST hasn’t undergone any major design changes, but still remains a compact and lightweight option.

It can be used in wired situations, but really shines when used wirelessly, as it is easy to connect and to set up, making wireless presentations a dream.

Who Is this Pico Projector Designed for?

This is a very small, but highly powerful projector that was clearly designed for office presentations or to show videos or movies.

The small size of the Optoma ML750ST makes it perfect for traveling salesmen or businessmen to take with them to show their presentations to clients and then to be able to relax in the hotel with a great movie.

The portable design of the Optoma ML750ST speaks to how it is to be used on the road and how easily it can be taken on the go.

While it was designed for use by businesses, anyone, including churches, can benefit from the power and control that the Optoma ML750ST offers.

It’s small enough that it can be easily stored out of the way when not in use, and it is powerful enough to broadcast a presentation for a larger group.

Thanks to the lower price tag, it’s affordable for many churches who have a small or modest equipment budget.

Alternatives to the Optoma ML750ST

This projector only weighs two pounds but boasts an impressive 40,000 hours of LED lamp life. Thanks to the low cost of this projector, it really is perfect for churches who need to buy multiple projectors for use throughout the building.

Another great option is the ViewSonic M1 portable projector. This small projector is an obvious choice for anyone who loves great sound during movies or presentations.

The dual Harman Kardon speakers are some of the best ones included in projectors today and are designed to deliver room-filling audio. This means that the overall movie or presentation will be even more impressive and immersive.
