Epson PowerLite 1751 XGA 3LCD Projector

The Epson PowerLite 1751 XGA 3LCD Projector is a sleek, featherweight data projector. It's a lower-priced alternative to the Editors' Choice Epson PowerLite 1761W Multimedia Projector, with lower resolution and more modest connectivity choices.

The Epson 1751 has a rated brightness of 2,600 lumens, and has XGA (1,024 by 768) native resolution It has a 4:3 aspect ratio that's traditionally been used for data presentations. Its light engine employs the 3LCD technology that Epson helped develop.

This black projector measures 2.1 by 11.5 by 8.3 inches (HWD) and weighs 3.7 pounds. The 1751 has both zoom (1.2:1) and focus wheels positioned behind the lens. I was able to bring the projector to a reasonably good focus. The projector comes with a soft carrying case, with two pouches for cables and the like.

The Powerlite 1751 has a typical selection of ports for a portable projector: VGA (which doubles as component video), HDMI, RCA video-in, audio in; a type B USB port for USB display as well as keyboard and mouse control; and a type A USB port for running a presentation off a USB thumb drive. Unlike the Epson 1761W or the Casio Slim XJ-A146 , it lacks WiFi capability.

Data Testing
I tested the Powerlite 1751 about five feet away from the screen, where our test image filled the screen (about 60 inches on a diagonal). The image was bright enough to stand up to a fair amount of ambient light.

The Powerlite 1751's data image quality, as tested using the DisplayMate suite, should be fine for typical business presentations. A strong point was text: type was readable at all sizes, though white-on-black type was slightly blurred at the smallest size. Some pixel jitter was visible in certain images over a VGA connection; it disappeared when I switched to HDMI. I noticed some tinting in images with gray or white backgrounds; although it wasn't severe, it was a little more pronounced than with the Epson 1761W, about on the level that I saw with the Casio XJ-A146.

Video and Sound
Video quality was above average for a data projector, good enough for video clips of any length as part of a presentation. You could even use it to show movies, though color wasn't particularly accurate. Skin tones looked overly red in some scenes, and in a hospital scene, white patient gowns often looked a touch bluish. As an LCD-based projector, its video is free of the distracting rainbow artifacts often seen with DLP projectors.

Audio from the 1-watt speaker is of reasonable quality and of modest volume, adequate for use in a smallish conference room.

Bulb Life
The Powerlite 1751's lamp life is rated at up to 4,000 hours. Although that's good for data projector, it doesn't begin to approach that of the Casio Slim XJ-A146, whose hybrid LED-laser light engine's bulb can last up to 20,000 hours, essentially the lifetime of the projector. Although the Epson 1751 costs considerably less than Casio XJ-A146, you may have to replace the Epson's lamp, at $200 a pop, every few years, which could make up the price difference over time.

As an LCD projector, the Powerlite 1751's video is free of the rainbow effect often seen in DLP projectors such as the Casio XJ-A146, a slim and light projector with nearly the same specs and dimensions as the Powerlite 1751, though it does include a Wi-Fi adapter and is more than a pound heavier than the Epson.

The Powerlite 1751 comes in at a lower price than the Editors' Choice Epson PowerLite 1761W, though it has lower resolution (and not quite as good data image quality), and lacks that projector's Wi-Fi capabilities.

The Epson PowerLite 1751 XGA 3LCD Projector is an appealing, lightweight portable data projector with very good video image quality for a business projector, and data image quality suitable for typical presentations. It provides a lower-priced alternative to several similar but WiFi-enabled thin-and-light data projectors. If you don't need wireless connectivity, it could well be your projector of choice.
