Classroom and Conference Room Projector Review
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.
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.
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.
