Optoma ML550
Portable LED Projector

Marc Davidson, December 16, 2013

Limitations

The only limitations worth mention that I ran into with the ML550 are typical for this category of projector.

Low audio volume. The 1-watt speaker is loud enough for a group of two or three people close to the projector, but low quality. If you need sound, you'll be better off with an external audio system or headset.

No zoom. As already mentioned, the ML550 lacks a zoom lens.

3D is highly limited. The 3D support is strictly for use with computers. As a practical matter, it's actually even more limited than that suggests, since 3D effectively cuts brightness by more than half.

Conclusion

Compared with other portable LED projectors, the Optoma ML550 offers the advantage of being smaller and lighter than most models with similar brightness, and brighter than most models with a similar size and weight. It can also free you from carrying or even needing to connect to bulky image sources like laptops. Instead, you can use a USB Key, microSD card, the projector's own internal memory, or a cell phone or tablet. Add in the good data image quality, watchable video, and sub-$500 price, and the ML550 is well worth a look.

You've got to watch the claims of long LED lamp life. It's more than a bit of a scam: over time the lamp gets dimmer and dimmer. On my Acer unit a note popped up on the screen at around 2000 hours advising that it would no longer produce the light necessary for bright mode and suggesting lamp replacement. It was impossible to get hold of Acer to make my complaint. The performance of that projector is now increasingly wishy-washy so I'd suggest you view LED projectors as primarily good for portability particularly as more conventional projectors have lamps that last over 4000 hours now.

If the ML550 is the projector you are saying I am getting for $100 more than projector X to get 500 Lumen (and any of the other features) over the 300 or 400 lumen projector you were originally looking at.

You can keep saying well, this one is only $X more....

Why would you buy the ML550 when for $100 more you could buy the ML750?
