Optoma ML550 review

The brightest, nicest and best connected palm projector yet

TODO alt text

Setting-up the ML550 is a cinch, with an adjustable drop-down foot on the projector's undercarriage allowing easy aim, with the zoom lens - despite it being digital - proving just savvy enough to create a pristine, straight image.

Whatever flash-based source we supplied the ML550 with, it lapped-up everything we threw at it, including all Microsoft Office formats, JPEG photos, and video files a-plenty (everything from AVI and MKV to WMV, MP4, H.264 and MOV).

Some files take longer to load than others, but the media player software supplied on the ML550 makes navigation of files and folders quick, easy and simple. There really is no need for a laptop.

Optoma ML550 review

The best thing about the ML550 is its brightness, which means that a total blackout isn't necessary. The detail on show on our 90-inch test screen was reasonably impressive, and though it's at a 60-inch-or-so size that the ML550 performs at its peak - from about two metres - even at the larger size we enjoyed its bright, smooth images.

In Photo, PC and Bright mode the text on an Excel spreadsheet appeared contrast-y and precise, while the graphics on a PowerPoint slide impressed with its colour saturation.

In most cases it's the PC mode that should do the job, though the slightly dimmer 'Cinema' preset is handy for watching movies, despite being rather basic.
