Optoma ML550 Projector - Overview

The Optoma ML550 Pocket projector is a powerful projector in a very compact package. It is rated at 500 lumens and from the look of things while reviewing the projector it certainly performed well. I will cover exact lumen readings in the Performance section of this review. The projector has a native resolution of 1280x800, but performs very well at it maximum resolution of 1680x1050.

The most important aspect of this projector is of course it size, its lamp life and its image quality. This projector is tiny, weighing in at 14.1 ounces. With LED light technology powering the image, expect the projector to perform for up to 20,000+ hours before needing to replace the unit. More than likely before 20,000 hours you will have upgraded to a newer model.

Being small doesn't mean it lacks features. The Optoma ML550 has an input for HDMI and also a USB input so you can display images and office files without having to hook up a computer. The projector features 1.5Gb of on-board memory. Oh, and it is 3D ready.


Optoma ML550 Special Features

No Computer Necessary

The ML550 is capable of reading office files and many other types. The onboard memory totaling 1.5 Gb means you will have plenty of space for your presentation. No need for a computer for a quick impromptu presentation. The formats it can play include: PowerPoint, Word, Excel and you can view PDF files. For video, the ML550 is capable of playing lots of formats like, .avi, .mkx, ,divx, .ts.dat, .vob, .mpg, .mpeg, .mov, .mp4, .rm, .rmvb, and .wmv.

MicroSD Slot

Above I talked about the projectors onboard memory, but the Optoma ML550 also has a MicroSD card slot. The largest card it will accept is 32 Gb. Plenty of space for even the most high resolution videos.
