Viewsonic PJD7820HD
Home Video Projector Review

Allan Abbott, August 5, 2013

Performance

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.

This only applies to 24hz 3D Viewing... Like Movies or LOW Frame rate PC Gaming... 24Hz

The Benq W1080ST/W1070 Have the X3 "Triple Flash" THIS gives them the total Refresh rate of 144Hz. - This only Applies to Games/Movies that are in 24Hz Resolution/Format -

24Hz X 3 Times (Triple Flash) = 72Hz/Per Eye = 144Hz Total Refresh Rate. - The Acer H6510BD is as follows - 24Hz X 2 Times (Normal double Flash) = 48Hz/Per Eye = 96Hz Total Refresh Rate.

This is how I figured it out. Seems that 144Hz only matters for 24hz 3D-Blueray Movies.

I have an HD23 and I'm looking foward to buying a 3D projector. I have noticed some Rainbown effect with the HD23 and althrough I have already get used to it I would like to get a projector that would give me less rainbown effect than the HD23. I use the HD23 on my living room and today I can use it to play videogames during the day, with closed windows. I have two projectors in mind: The PJD7820HD and HD131Xe (or Even the HD25). Which of these projectors creates less rainbow effect? Thanks

Is the 3D refresh rate 144Hz or 96Hz? Trying to decide between this and the Acer H6510BD

What about the lumens in 3d mode? You nice folks at ProjectorCentral measure it for other projectors. I would love your technical comparison against the Optoma HD25/LV.
