ViewSonic LX720-4K RGB 2,000 ANSI Lumens 4K RGB Laser Home Cinema Projector

ViewSonic LX720-4K RGB – 4K RGB Laser Home Cinema Projector

The ViewSonic LX720-4K RGB is a compact 4K UHD home projector that uses a red, green and blue laser light source to reproduce the full BT.2020 colour space. Rated at 2,000 ANSI lumens, it pairs true 3840 x 2160 resolution with HDR10 and HLG support for rich, cinematic pictures.

Aimed at film fans and gamers who want a big screen without a large chassis, it projects images up to 300 inches, offers a 1.3x optical zoom and flexible geometry correction, and cuts input lag to as little as 1ms for responsive play.

Key Features

• RGB laser light source – separate red, green and blue lasers cover 100% of BT.2020 for vivid, accurate colour

• HDMI ARC – send audio back to a soundbar or AV receiver over one cable
• 10W cube speaker – built-in sound for quick setups

Picture Quality

The RGB laser engine delivers a wider colour gamut than conventional phosphor laser or lamp projectors, exceeding DCI-P3 cinema coverage. A 3,000,000:1 dynamic contrast ratio and HDR/HLG processing help give films depth, while a low blue light mode supports comfortable long viewing sessions.

Installation and Throw

With a throw ratio of 1.136–1.477 and 1.3x optical zoom, the LX720-4K RGB fills a 100-inch screen from around 2.5 metres, with image sizes from 60 to 300 inches. Horizontal and vertical keystone (±25°), four-corner adjustment and warping make it easy to fit into real rooms.

Connectivity

Two HDMI 2.0 inputs with HDCP 2.2 accept 4K sources such as consoles, Blu-ray players and streaming sticks, and the second HDMI port supports ARC. A 5V/1.5A USB-A port can power a streaming dongle, and RS-232 is provided for control systems.
