Optoma EP1690
Widescreen Data/Multimedia Projector

Bill Livolsi, August 9, 2006

It is becoming increasingly common to see computers that output widescreen signals, whether they be laptops or desktops. As such, a new class of projectors is required which can natively display 16:9 and 15:9 signals while maintaining appropriate brightness and contrast levels for dynamic data projection. In this vein is the Optoma EP1690, a 1280x768 projector rated at 2500 ANSI lumens and 2500:1 contrast. It is light enough to serve as a portable projector, and is an ideal unit to couple with a widescreen laptop. It is bright enough for use in small to medium sized conference rooms and classrooms. It has good color and contrast, which makes it a good choice for video game enthusiasts, and it can be ceiling or coffee table mounted for convenience. While it can serve a secondary role as a video projector, the EP1690 really shines with high-contrast data material. This versatile package is available for under $1700, which is an excellent bargain.
