The Epson EB-1775W was announced in January 2011 and sits at the top of the company’s EB-1700 series of corporate portable multimedia projectors. There are three more models in the same series: EB-1750, EB-1760W, and EB-1770W. Visually, all four models look the same; though expectedly, the higher-end models have a few more tricks up their sleeves to justify their higher price tags.
All four projectors use the 3LCD technology. Compared to those that use the DLP (Digital Light Processing) technology, 3LCD projectors are typically brighter, and offer more accurate color reproduction. However, they’re also bigger in size, thus making them less attractive for executives looking for a projector to bring out and about.
However, the above does not apply to these new projectors from Epson. All four projectors in the EB-1700 series have a footprint no larger than an HWM magazine, and a thickness of just 44mm. At weight of 1.66 to 1.71kg, they’re also lighter than many 13-inch notebooks. Beyond these vital statistics, the projectors share plenty of similarities: 1.2x zoom lens, 1-Watt monaural audio output, USB Display, and Slideshow functions. With the exception of the EB-1750 that has a native resolution of 1024 x 768 (XGA), the others sport a widescreen, 1280 x 800 (WXGA) resolution. (This is the reason for the “W” at the end of their model numbers.) In addition, the widescreen models support the use of the ELPAP07 wireless LAN module and the ELPAP08 Quick Wireless Connection USB Key. These optional accessories can be had for S$130 and S$180 respectively. The bonus for getting the EB-1775W is that both come as standard.
