Description

The Vivitek DH3665ZN is a standard throw DLP projector with a native 1920 x 1080 resolution and a rated brightness of 4,500 ANSI lumens. A laser phosphor light source replaces the traditional lamp, so there are no lamps to change and brightness stays more consistent over the life of the unit.

Its main difference from a standard projector is the embedded NovoConnect platform. Laptops, tablets and phones running Windows, macOS, Ubuntu, Chromebook, Android or iOS can present wirelessly, up to four sources can be shown on screen at once, and moderation lets the host control who is presenting. Annotation tools are also built in.

For installation it offers a 1.5x zoom (1.39 to 2.09:1 throw ratio), keystone correction of up to 30 degrees in both directions and a full set of wired inputs, including two HDMI, VGA, composite, LAN and RS-232. Vivitek positions it for medium-sized meeting rooms, and NovoConnect is offered in corporate and education editions.

Planning from a real wall? Use the projector screen size calculator to upload a photo, preview the image to scale and find projectors that fit within your maximum available space. Replacing an existing projector? The projector replacement calculator checks whether this lens covers the ratio your current mount needs.

Distances are lens-to-screen, calculated from the manufacturer's stated throw ratio; allow for lens shift and mounting hardware. Always confirm against the manufacturer's installation guide before fixing mounts.
