JVC DLA-NZ9 throw distance & placement
Problem. A premium home cinema build around the JVC DLA-NZ9 needs to know how much room depth a 120-inch 16:9 screen actually demands before the projection bay or rear shelf is framed in. Because the NZ9 carries a 2.0x zoom lens rather than a fixed-ratio lens, the real question is not one throw distance but a placement range.
Answer. For a 120-inch 16:9 screen (2.66 m wide), the JVC DLA-NZ9 throws from 3.59 m to 7.26 m. That 3.67 m of placement latitude means the projector can sit on a rear shelf, a mid-room ceiling mount, or further back near a rear wall, and still fill the same 120-inch image.

How this preset reads — the engineering view.
The DLA-NZ9 uses a zoom lens with a throw ratio of 1.35-2.73:1, which is what produces the 3.59-7.26 m range at 120 inches. A fixed-ratio projector would give a single number; this lens gives a placement window, so the room layout can flex around furniture, doorways or a rear-wall equipment position instead of dictating them.
At 3000 lumens, the NZ9 is specified for a light-controlled or dedicated home cinema room rather than a daylight-bright living space; pushing it against strong ambient light will cost contrast before it costs brightness headroom. The native 4096x2160 imaging chip means the panel resolution itself is true 4K DCI, not a pixel-shifted approximation, and the laser light source removes lamp-replacement cycles from the long-term maintenance conversation.
From here, drag the screen-size slider to see the 3.59-7.26 m throw window move with it: a smaller screen shortens both ends of the range, a larger one lengthens them. The zoom and lens-shift latitude this model offers is exactly what lets you test a few candidate mount positions in the same room before settling on one.
The calculator stops at throw geometry. It does not model screen gain or ambient-light rejection (both change perceived contrast independent of throw), does not size a ceiling or rear-shelf mount, does not select a specific lens variant on interchangeable-lens bodies, and says nothing about the audio layer of the room. Those sit alongside this placement decision, not inside it.
What this preset deliberately does not solve
- Throw figures assume the standard zoom lens; interchangeable-lens variants of this model class can shift the range.
- 3000 lumens is a light-controlled-room specification, not a daylight-viewing one.
- Lens shift range and mounting offset are not modelled by this calculator and should be checked against the projector's optical specification.
How this preset differs from its siblings
Other premium home cinema projectors in this class often carry narrower or fixed-ratio lenses, which collapse the placement question to a single throw distance rather than a range. The DLA-NZ9's wider 2.0x zoom (1.35-2.73:1) gives markedly more placement latitude at the same 120-inch screen size, which is why its throw window is treated as a distinct preset rather than folded into a generic home-cinema default.
