Ease of use and quality of images were key factors in rating portable projectors

The GCN Lab invited vendors to participate in a roundup review of ultraportable multimedia projectors.

The lab required that the units project at 800 lumens or more, weigh less than 15 pounds, and support 1,024- by 768-pixel resolution or higher. Each company could submit only one unit.

Lab personnel set up each projector as directed in the instructions, verified that the unit worked, and sent video and audio signals from a variety of sources.

Performance was judged by the following characteristics, each counting equally in the overall grade:

• Ease of use: Setup process, on-unit controls, clarity of input and output connections, drivers and other software, and other contributing features

• Brightness and color accuracy: Brightness of static images in a fluorescent-lit room at a distance of 20 feet from the screen, and color accuracy compared against a notebook LCD showing the same image in a semidark room

• Remote control: General performance, control from all areas of a conference room, and extras such as a laser pointer and mouse control of a notebook computer

• Static image quality: Overall quality including smoothly defined edges, accurate representation and visibility of subtle details

• Moving video image quality: Overall performance on motion pictures sent from a computer and a television video source

• Portability: Weight, location of the unit's handle and whether the unit came with a carrying case.


Lab personnel John Breeden II, Jason Byrne, Donovan Campbell and Michael Cheek contributed to this review.
