The BenQ MX661 is designed primarily for corporate settings good brightness and resolution, solid data image quality, portability, a good selection of connectivity ports, a substantial zoom ratio, and 3D capability among them.
The DLP-based MX661 has XGA (1,024 by 768) native resolution at a 4:3 aspect ratio, and a rated brightness of 3,000 lumens. The projector is black on the base and top, with white sides and rounded corners. Its zoom ratio is a useful 1.3:1. The projector measures 4.9 by 12.8 by 9.1 inches (HWD) and weighs 5.7 pounds. It includes a carrying case.
A strong point for the MX661 is its abundance of connection ports, including 2 VGA ports (which can double as component video); monitor-out; HDMI; S-video; an RCA jack for composite video; audio-in; audio-out; microphone-in; serial; Ethernet; a USB type B port (for downloads and to control Page Up/Page Down); mini-USB type B port (for downloads and for USB Display, which emulates what’s on your computer screen), and a USB type A port for running a presentation from a USB thumb drive. (File types supported are JPEG, JPG, BMP, PNG, GIF and TIFF).
Data Image Testing
The MX661 projected an image about 60 inches diagonal to fill our test screen from about 8 feet away. The image stood up to a good amount of ambient light without notable degradation.
In data image testing, using the using the DisplayMate suite, the BenQ MX661′s image quality was average for a DLP projector of its resolution, suitable for typical business and classroom presentations. In our text testing, type was somewhat blurred at the two smallest white-on-black sizes, with the smallest size difficult to read. There was mild yellow tinting in white areas in some images. Though colors generally looked good, yellows tended to be on the dull side.
I saw rainbow artifacts, little red-green-blue flashes in light areas against dark backgrounds, in images that tend to bring them out. They tend not to be an issue in data presentations, though, even for people sensitive to this so-called rainbow effect, which is often seen with DLP projectors. Some images with hatched patterns showed greenish tints and pixel jitter. When I switched from a VGA connection to HDMI, the green tinting and pixel jitter disappeared, and there were fewer rainbow artifacts.
Video and Audio
Video quality was reasonably good for a data projector, suitable for showing short to mid-length clips as part of a presentation. The rainbow effect was visible in scenes that tend to bring it out. Though it wasn’t particularly severe, it would likely be distracting to people sensitive to it. Color balance was good, and skin tones looked reasonably true. There was some loss of detail in bright areas.
Audio from the single 2-watt speaker was on the soft side, loud enough to fill a small room, and of reasonably good quality.
The MX661 has several eco-friendly features. Its expected lamp life is up to 6,500 hours. Its EcoBlank mode lets presenters blank out the screen while taking a break lowering energy consumption up to 70% while it’s paused. Also, the projector will automatically enter EcoBlank mode after 3 minutes without a signal. SmartEco mode automatically adjusts lamp brightness, depending on lighting conditions.
This projector is 3D-capable, with support for 3D Blu-Ray via HDMI as well as Nvidia 3DTV Play, enabling it to display 3D content from NVIDIA 3D Vision. Active-shutter 3D glasses are not included.
The MX661′s 3D capabilities are one thing that’s missing from two Editors’ Choice XGA projectors, the Epson PowerLite 1835 XGA 3LCD Projector, a brighter (3,500 lumens), heavier business or classroom projector, and the Epson PowerLite 93+, a portable 2,600-lumen budget model. Both Epsons offer very good data and video image quality, and as LCD projectors they’re free of rainbow artifacts. They both have louder sound systems than the BenQ. The MX661 has a slightly wider selection of ports than the 1835, and a much wider set than the 93+.
The BenQ MX661 provides a much better range of connectivity options than the BenQ MX518, also an XGA-resolution data projector. The MX518 provides solid data image quality, with its video image quality slightly inferior to the MX661′s.
It’s easy to recommend the BenQ MX661 as a business projector for its wide range of connection choices and solid data and video quality. Its portability and 3D capabilities are nice pluses. Though its image quality may not be top of the line, it’s more than good enough for typical uses a business might put it to.
