Home Video Projector Review

Brightness and Uniformity - The PJD7820HD exceeded its brightness specification in Brightest Mode with Brilliant Color on by delivering 3,330 ANSI lumens. The other Presets provided the following readings: PC and Dynamic PC - 2,520 lumens, ViewMatch - 2,265 lumens, Movie and Dynamic Movie - 1,700 lumens, and Gaming - 2,365 lumens. Brightness uniformity was 67% with the brightest part of the image in the lower center.
Color Brightness - Like many non-home theater DLP-based projectors, the PJD7820HD loses about 50% of its brightness when switched to its most color-balanced mode (Brilliant Color off). But if color balance is not critical or the room's ambient light demands higher image brightness, then turning Brilliant Color on may be a good choice.
Input lag - Gamers will be happy to hear that the PJD7820HD's various image modes all measured 17ms, or one frame, of delay with a native-resolution signal source. For those requiring fast reaction times, the PJD7820HD provides a responsive platform.
Image Size and Offset - Projecting a 100" diagonal image requires a projection distance of between 8'5" and 10'11" from the screen. The centerline of the lens is 6" below the bottom of the image at those distances, so tabletop mounting works well.
Menu Selection and Navigation - There are six menus for the PJD7820HD, but they are easy to navigate. Most of the settings you are likely to need are found in the Display and Picture menus, and the dual User modes allow you to store two sets of preferred settings. This makes for a quick set-up for two different viewing situations (for example, daytime and nighttime) without the hassle of changing settings manually.
Remote Control - The PJD7820HD's full size remote control is sectioned into four distinct functional areas: source selection, menu navigation, specific function keys, and page/mouse controls when the USB-B cable is connected to a computer. With source selection enabled, one key will sequence through the connected sources, but there are also dedicated keys for direct selection of VGA and video inputs.
