Description and Benefits

The BenQ LH660 is a Full HD laser projector with a brightness of 4600 ANSI lumens, designed for conference and meeting rooms where clear images and good readability are required even in the presence of ambient light. The combination of native 1080p resolution and 93% Rec. 709 coverage provides detailed reproduction of presentations, documents, and graphical content.

The 1.3x Big Zoom provides greater installation flexibility, including when projecting a large image from a distance of 2–3 m. The built-in automatic 2D Keystone correction makes it easier to adjust image geometry during installation.

Through RJ45, the projector can be connected to a corporate network for centralized management and OTA firmware updates via the BenQ QOTA cloud and Device Management Solution. Support for AMX and PJ-Link enables integration with control systems and existing IT infrastructure.

When using the optional QP30 or EZC-5201BS, wireless screen sharing is possible. The laser light source provides up to 20,000 hours of operation in Normal mode and up to 30,000 hours in ECO mode, reducing the need for maintenance and consumable replacement.

The built-in 15W speaker enables audio playback without the need for a separate audio system in standard presentation scenarios.
