Description
The ViewSonic LX720-4K RGB turns a living room into a full colour-gamut home theatre with a Triple Laser RGB light source. Unlike phosphor laser designs, it produces red, green and blue light directly, giving full coverage of the wide BT.2020 colour space for noticeably richer, more accurate colour.
Rated at 2,000 ANSI lumens (equivalent to 4,800 RGB Laser Lumens by ViewSonic's own measure), the LX720-4K RGB resolves native 3,840 x 2160 4K UHD across more than 8.3 million pixels, backed by a 3,000,000:1 contrast ratio and a light source good for 20,000 hours in normal mode, 30,000 in eco mode.
Gamers benefit from 1ms input lag, variable refresh rate support and up to 240Hz at 1080p, while a 1.3x optical zoom and built-in Google TV with wireless casting make everyday setup and streaming straightforward.

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.
