Epson PowerLite 435W Multimedia Projector


The Epson PowerLite 435W Multimedia Projector ($1,149 direct) is an appealing short-throw projector for classroom or business use, capable of throwing a large image when placed close to the screen. It has a good selection of connectivity ports, with optional WiFi. In our testing, it showed above-par video quality for a data projector. Although its data image quality isn't up to the best in its class, the 435W is well worth considering if you're in the market for a short-throw projector.

The 435W, rated at 3,000 lumens, has native WXGA (1,280-by-800) resolution, and a 16:10 widescreen aspect ratio compatible with many laptops. The projector employs a light engine that uses 3LCD technology, which Epson helped develop.

The two-tone (white and gray) projector measures 6.2 by 13.6 by 11.7 inches (HWD) and weighs 8.7 pounds, large enough so you wouldn't want to travel with it regularly. (Epson sells ceiling mount accessories should you want to permanently install it.) As is typical of a short-throw projector, the lens assembly resembles a large, bulbous eye. Behind it is a focus slider, with which I was able to bring the projector to a good focus.

The 435W has a generous selection of ports: two VGA-in with audio jacks; a monitor-out VGA port (with an audio-out jack); HDMI-in; 3 RCA plugs for composite video and audio; S-video; a type B USB port for connecting with a PC (USB Plug ?n Play provides easy connectivity with both Macs and Windows PCs); a USB type A port that fits a thumb drive; RS-232C; an Ethernet port; and a microphone jack. An optional WiFi adapter is also available ($99 direct).

Testing
The 435W's image filled our 60-inch-diagonal test screen from just under feet away. The image was bright enough to show up well even with modest ambient light. In our DisplayMate ?testing, the PowerLite 435W?s data image quality proved suitable for typical classroom or business presentations. Smaller-sized type wasn't quite as sharp as we expect from a data projector. Some data images showed traces of red or green tinting, while borders between bright and dark areas at times showed blue or yellow fringing.

Video quality was above average for a data projector, making the 435W suitable for showing short or medium-length clips as part of a presentation. Sound from the single 16W speaker was loud enough to fill a mid-sized room, though you'll want to turn it down a bit as there was some distortion (crackling) at higher volumes.

The 435W's lamp lifetime is rated at up to 6,000 hours in Eco mode, and up to 4,000 hours in normal mode, both good figures. You shouldn't have to replace the bulb very often, if ever.

If you're looking for a short-throw WXGA projector for school or business use, the Epson PowerLite 435W is worth putting on your short list alongside two Editors' Choice models, the Optoma TW610ST ($1,000 street, 4 stars) and the NEC Display Solutions NP-M300WS ($1,099 direct). Both have largely similar feature sets to the 435W, but offer better data image quality?though the Epson's image quality is fine for typical business presentations.

The Epson PowerLite 435W Multimedia Projector is a good choice if you use a lot of video in business or classroom presentations. Both the 435W and the NEC NP-M300WS displayed very good video quality in our testing, and both have thumping sound systems?though you might not want to play the Epson's at full volume, as it crackles a bit. As they're LCD based, these two projectors' video is free of the rainbow effect common in DLP projectors (in which little glints of the three primary colors appear, mostly in moving images) that impacted the TW610ST's video quality. However, as a DLP projector, the Optoma supports 3D viewing using DLP-link glasses (sold separately), while the Epson and NEC projectors have no 3D capabilities.
