Description

The ViewSonic LX750-4KB is a 4K HDR smart laser projector built for a full home cinema experience without external boxes. Its 3rd-generation phosphor laser light source delivers 4,000 ANSI lumens and is rated for up to 30,000 hours in eco mode, replacing traditional lamps with a more stable, long-life light source.

Native 3,840 x 2160 resolution resolves the full 8.3 million pixels of 4K content, enhanced by HDR/HLG and 3D support and backed by a 3,000,000:1 contrast ratio. Built-in Google TV brings Netflix, YouTube and Disney+ straight out of the box, while HDMI ARC sends audio and video over a single cable to an external sound system.

A 1.3x optical zoom, dual H/V keystone correction (±25°) and four-corner adjustment make it simple to place the LX750-4KB flexibly and still fill a screen up to 300 inches, and its reflective, blue-light-reduced image is designed to be easier on the eyes over long viewing sessions.

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.
