NEC Display Solutions NP19ZL-4K 2.22-3.67:1 zoom lens for PX1005QL projectors

Lens specification and intended use

The NEC NP19ZL-4K is a medium-throw zoom lens designed exclusively for the NP-PX1005QL-B and NP-PX1005QL-W projectors. It provides a 2.22 to 3.67:1 throw ratio with lens shift and lens memory functions. Installers select this accessory when the projector must be positioned at a moderate distance from the screen. It is not for venues requiring ultra-short or long-throw optics.

Throw ratio limits

The zoom range spans 2.22:1 at its widest setting to 3.67:1 at its narrowest, defining the practical placement window for a given image width. Lens shift adds vertical and horizontal adjustment without moving the projector, while lens memory stores those positions for quick recall. The fixed ratio endpoints mean the lens cannot cover throw distances outside this interval.

Capacity and headroom

The lens comfortably handles typical auditorium and conference-room throws where the projector sits roughly two to four times the image width away. Lens memory reduces setup time when switching between screen formats or aspect ratios. It runs out when the installation demands a throw ratio below 2.22:1 or above 3.67:1, requiring a different lens model.
