NEC NP41


by Rich Malloy
Price as Reviewed $999

In contrast to the sleek Casio XJ-S57, the new NEC NP41 is a white, utilitarian box. There’s no fancy lens cap here; an ordinary translucent plastic disk pops onto the lens aperture the way such items have always done. And, at 3.6 pounds, this model is the lightest projector in this roundup, but certainly not the lightest we have seen recently.

The connectors on the projector’s rear panel cover just the bare minimum: VGA (which doubles as the component video input with an optional cable), S-Video, composite video, and a mini audio socket. There is also a PS2-style round “control” port.

Although relatively large, the remote control has only a few useful controls. These include the somewhat standard but infrequently used digital-zoom buttons.

The best part of this projector is something that is missing: a focus ring around the lens. The reason? The focusing is done automatically and rather skillfully by the projector itself. The projector also automatically compensates for any trapezoidal or keystone image effects, but because such compensation usually degrades image quality, we turned this feature off via NP41’s on-screen menu.

On our tests, this projector scored quite well. Its brightness of 2210 lumens was just a tad shy of the advertised mark of 2300. In our checkerboard contrast test—a more realistic analysis than the industry-standard full-on/full-off test—the NEC scored a ratio of 534:1, which is one of the higher marks we have seen, and the highest in this roundup.

We really appreciated the speedy warm-up and cooldown times, the latter being an impressively short 14 seconds. Subjectively, we like the color capabilities, especially some nice bright yellows, which is rare for DLP projectors. The cooling fan was a bit noisy, however, even in low-power Eco mode.

With a price tag of $999, including a two-year warranty, the NEC NP41 is one of the lower-priced XGA projectors capable of more than 2000 lumens of brightness. Add in the automatic focusing feature, and it becomes a real bargain.

Panasonic PT LB60U


Price as Reviewed $1,195.00 - $1,383.99

This small LCD projector's Daylight View 2 feature caught my eye - literally. The projector has a built-in sensor that measures the ambient light, and then adjusts the halftone colors and brightness level accordingly, giving sharp "true colour" images no matter what the light conditions. Combined with XGA (1024 x 768) resolution, 3200 lumens, a 400 to 1 contrast ratio and a weight of 5.5 pounds, this LCD projector makes giving worry free presentations in a variety of venues easy.

Understanding Front-projection TVs - LCD

LCD and DLP are very close in terms of performance, and even LCD's ability to produce good blacks has improved quite a bit. DLP still enjoys a slight edge in contrast ratio, however, mainly because its projectors can get a bit brighter than those of LCDs. The screen-door effect, which appears as a fine grid of pixels overlaying the screen, is also more noticeable on most LCD projectors. As we mentioned above, however, 720p LCD projectors still enjoy more features than their budget 720p DLP competition, including highly desirable items such as horizontal and vertical lens shift. No consumer-priced 1080p LCD projectors are currently available.

Upside
Can get extremely bright; decent uniformity; generally better black-level performance than LCD.

Downside
More expensive than similar-resolution LCD models; rainbow effect.

Forecast
Already the most popular technology for home-theater projection, new less-expensive 720p versions will make DLP even more desirable.

Optoma EP727




by Rich Malloy
Current Price: $689.00 - $866.86

Shhh. If you listen carefully, you can hear an entire category of low-resolution SVGA projectors going extinct. Their low-budget niche has been invaded by the amazing Optoma EP727, which boasts XGA resolution, a highly portable design, and a price tag of just $699.

Good Performance and Features for the Price

If that’s not enough, check out the full-featured remote (which includes both a laser pointer and a set of mouse pointer controls) and the relatively wide range of inputs. Not only is there a VGA-out connector for users of obsolete desktops, but there is also a choice of two VGA inputs, using the traditional VGA and the newer DVI connectors (which can be used simultaneously for quick handoffs from one presenter to another). We also like the Velcro straps on the VGA and USB cables for neat and easy stowage.

On our tests, the EP727 presented sharp images and was adequately bright for most applications (1,466 ANSI lumens versus the 2,200 advertised). The contrast ratio was a very impressive 591:1, thanks to its DLP imaging engine. However, like many DLP models, its yellows looked a bit too much like deli mustard. The projector shut down in a sprightly 18 seconds (although it was still warm to the touch) but needed a leisurely 40 seconds to warm up. Even though we had a difficult time doing it, we liked that you can shift EP727 into low-power mode, which for this unit means less noise from the cooling fan and a longer life for the lamp (3,000 hours vs. 2,000 in Bright mode), and a 12 percent decrease in brightness.

A Few Weaknesses

Sure, a couple of aspects of the EP727 could be improved. Although the remote control has an impressive set of features (including numeric keys for inputting a theft-deterring password), most of the buttons are arranged poorly and could easily confuse a nervous presenter. Likewise, the Power button on the top panel of the projector is difficult to identify. Also, the menu structure is a bit more complicated than it needs to be. Finally, the back panel has a surprising omission: an RCA-style video connector, which is usurped by the S-Video connector.

Verdict

The above are minor quibbles, however, especially for a $700 XGA projector that is sure to kill off an entire species of low-resolution budget models. Yes, there are certainly brighter projectors available, but none has the impressive combination of price and features available in the Optoma EP727.
