Sharp's new 2,700-lumen PG-D2710X data/video projector is roughly 20% smaller than most competitors in its class. It is 3-D ready, handles a wide variety of inputs, and has its own proprietary networking software. Classroom and conference room presenters will appreciate the highlighting features on its remote control. And a Color Management System enables tweaking of saturation and hue of all six segments of the color wheel. The PG-D2710X is a high performance XGA projector street-priced at just $748.

Overview

The PG-D2710X is a portable XGA projector that measures only 11-13/16"W x 3-1/8"H x 9-5/16"D making it the lowest profile projector in its class. At 6.2 pounds, it is easy to carry, and it has a captive sliding lens cover that will not get lost. Fan noise is modest and thankfully lacks the high frequency whine of some DLP projectors.

A wide variety of computer and video inputs is accommodated: from VGA to UXGA with everything above XGA seamlessly scaled by Sharp's intelligent compression algorithm. Video signals can range from 480i to 1080p/60. The PG-D2710X is one of the few projectors in its class that can take a 1080p input input.

For those looking forward to the emergence of more 3-D content, the PG-D2710X is compatible with TI's DLP Link protocol which combines with separate LCD shutter glasses to deliver the 3-D experience.

Network and Web connections via RS-232 and RJ-45 connections are complemented by Sharp's downloadable Display Manager network software for projector management and theft monitoring. The ubiquitous Kensington lock has a companion security bar at the rear of the projector.

Brightness and Uniformity: With BrilliantColor on in its Presentation mode, the PG-D2710X put 2,350 ANSI lumens on the screen, just a little shy of its rated output. In its other preset modes, brightness was reduced to 1,445 lumens in Movie, 790 lumens in sRGB, and 1,605 lumens in both Standard and Game modes. Brightness uniformity came in at just over 77% with the brightness peaking in the lower right portion of the image.

Image Size and Position: Theoretical image size ranges from 40" to 300" at projection distances from 4.6' to 41.3", respectively. Practically speaking, it will throw a 100" diagonal 4:3 image from about 12.5 feet, give or take a foot. The 1.2x manual zoom lens gives you a little flexibility in lining up the image with a screen.

There is not much upward throw angle. The bottom of the projected image is just slightly above the centerline of the lens. For tabletop use, this suggests that you may have to tilt the projector upward and use the ± 30° keystone adjustment to square up the image. An elevator-style front foot tilts the projector vertically when necessary, and the right rear foot may be raised or lowered to compensate for any horizontal tilt of the projection surface

Remote Control: The full-size remote is well laid out, and even the lowermost buttons can be reached comfortably. Preset modes, the Eco lamp setting, and presenter features like a movable pointer and a highlight rectangle are available at the touch of a button. Keystone adjustment and even screen resizing can be accomplished without going into the on-screen menu system. There is no backlighting, but this projector is not typically one that will be used in the dark.

Connections: There are two VGA connectors, one of which can serve either as an input connector or as the monitor loop through output. The VGA connectors also serve as the component video inputs, and there are composite and s-video inputs as well. Two audio inputs (one RCA and one mini jack) are complemented by a mini jack audio output. For network and Web connections, there are separate RS-232 and RJ-45 connectors as well as a mini USB port.

Presets: You can choose from three preset color temperatures and five preset modes. While the brightness measurement for the Movie preset with Eco mode off was 1,445 lumens, switching to Movie mode automatically switches Eco mode on. The brightness drops to 910 lumens. Fan noise is also reduced which makes the speakers more effective as well.

Lamp Life: The PG-D2710X uses a 210-watt lamp that is rated for 2,000 hours at full brightness. However, Eco mode extends the lamp life to 4,000 hours although you give up about 29% of the screen brightness to get that lamp life extension.

Warranty: Sharp offers a 3-year warranty on parts and labor for the PG-D2710X. The lamp is covered for 90 days from the date of purchase.

Maintenance: Like most projectors of its type, the PG-D2710X's DLP chip is sealed so no air filters are needed. An occasional vacuuming of the intake grills is recommended to keep dust from accumulating and restricting airflow. One maintenance complication is that the lamp is accessed through the bottom of the case, so for ceiling-mounted units, the lamp replacement task is a bit cumbersome.

Advantages

Image Quality: As with many DLP projectors, the high contrast ratio of the PG-D2710X makes for crisp text and graphic images. Data images are well saturated, and small typefaces are still very readable even with maximum keystone correction applied. Computer-based photos and video are vivid and, as described earlier, can be color adjusted . . . an unusual capability in an inexpensive projector.

Video images have good dynamic range with well-defined black levels and highlights evident in all but the most demanding scenes. Best video quality is achieved with BrilliantColor off and the lamp set to Eco mode. The Movie preset mode comes pretty close to nailing skin tones, but you may want to reduce color saturation to get the best result.

Image Sharpness: Images with complexity and detail are sharp and crisp from side to side and top to bottom. There was virtually no screen-door effect at normal viewing distances.

Color Adjustment: The PG-D2710X has an extensive Color Management System that lets you vary the hue and intensity of the six color wheel segments (red, yellow, green, cyan, blue, and magenta). Many projectors, including this one, disable the saturation and tint settings for data images. For the others it means that you must live with whatever preset mode settings give you, but even in data mode, the PG-D2710X allows you to adjust saturation and hue in the Picture menu.

Audio Quality: Audio output rated at seven watts. This level is sufficient for small-to-medium rooms, and an audio mini-jack is available is external amplification is needed. The speaker is buzz- and hiss-free to the top of its output range.

On-Screen Menus: The PG-D2710X follows a trend toward shorter, multiple menus that group settings more logically and make it easier to find a particular function. Six menus allow image, signal sync, screen configuration, and projection adjustments along with a separate menu for network setup. The on-screen Picture menu settings collapse to a single-function bar at the bottom of the image when making most adjustments. This allows you to view nearly the entire image as you adjust brightness, contrast, and other picture controls.

Limitations

No User Memory: You can adjust image settings in all preset modes, and the PG-D2710X will remember those settings. But if the projector changes hands, it may come back to you with a few of those settings changed. Many projectors offer a User Memory mode where your unique adjustments are stored, but this projector does not have this feature, so you may have to spend a moment readjusting to your favorite settings if you have shared the projector with a colleague.

No Digital Input: There is no way to connect DVI or HDMI to the PG-D2710X. However, in an XGA resolution projector, the difference in image quality between digital and RGB or component is so subtle as to be insignificant.

Uniformity: At 77%, the brightness uniformity of our PG-D2710X test unit is a little lower than some of its competitors, and its nearly 500-lumen brightness difference from upper left to lower right of the image is noticeable when projecting a white screen. This difference may be seen in data mode when viewing spreadsheets or text documents, but it is unlikely that it will be noticeable with photo or video images.

Conclusion

Sharp has packed a lot of performance into a small package with their PG-D2710X. It is unobtrusive, simple to set up, and easy on the budget. It serves the dual role of data and video projector as well as any projector in its class, and its remote has some easy-to-use highlighting features. If you can live without a digital input, Sharp's new PG-D2710X is a presenter's dream.
