When it comes to placement flexibility, the JVC is first-class. Most projectors for home have zoom lenses with 1.1:1 out to 1.6:1, depending on the brand and model. This JVC offers 2.0:1 an excellent amount, and about the maximum zoom range available today. Others that tend to have that much range are mostly made by Sony and Epson, which are JVC’s primary competition.
The DLA-NX7, like most 3LCD and LCoS projectors, offers a lot of lens shift range but most DLP projectors offer very little. Projectors like this DLA-NX7, offer tons of installation flexibility for ceiling, rear shelf mount, or tabletop mounting the projector.
Here’s the throw distances for the DLA-NX7 for filling a 100” 16:9 screen (measured from the front of the lens to the screen):
Closest: 124.4 inches (10 feet 4.4 inches)
Furthest: 253.9 inches (21 feet 1.9 inches)
The JVC has lots of horizontal shift if you can’t line up the projector lens with the center of the screen (left to right). Just remember, like most projectors, the more horizontal shift you use, the less vertical adjustment you will have available.
Len Shift: 80% Vertical and 34% Horizontal
For a 100″ diagonal 16:9 screen: 80% of a screen height of approximately 50″ is approximately 40 inches. The DLA-NX7 can be placed with the center of the lens as high as about 20 inches above the top of the screen to 20 inches below the bottom, and anywhere in between. The horizontal shift is a maximum of 0.34 x image width, which would be about .34 x 87 inches for a total range of about 30 inches of horizontal adjustment. The large amount of vertical and horizontal shift makes rear shelf placement a breeze.
