2nd Generation Laser Phosphor Technology

The LS710HD adopts the 2nd generation laser phosphor technology. In addition to inheriting excellent color performance, lamp-free design, and instant power on/off from the previous generation, technology on the new generation improves around 20% of brightness, better heat-resistance, and a smaller module design, making the images consistent in ambient settings as well as increased reliability with a more compact size for extended use in various scenarios.

High Brightness for Large Venues

Thanks to 4,200 ANSI Lumens brightness, you're guaranteed clear visuals of vibrancy with 1080p Full HD resolution which are perfectly suitable for large spaces with a lot of ambient light.

Ultra-Large Screen with Lower Cost-per-inch

The projector allows for an up-to-300” image size, which is much larger and easier to install than commercial displays.

V Lens Shift for Flexible Installation

The tool-free, lens shift control knobs make adjusting the projection lens up and down easy. Welcome flexible installation options with an adjustable range (V: 0%, -18%) and fewer placement restrictions.

Effortless Image Adjustment

Horizontal and Vertical Keystone correction along with 4 corner adjustment features eliminate crooked or distorted images for a perfectly proportioned picture every time.

Adaptable to Any Environment with Optical Zoom

Equipped with a 1.6x optical zoom lens, the projector allows users to choose the most ideal set-up location within a range, getting the desired image size without needing to change the existing interior design. ​

Lighter Weight and Compact Size​

The LS751HD is 24% lighter of weight and 34% smaller in size compared to its predecessor, which reduces the cost of transportation and enhances the ease of installation.

Effortless Image Adjustment

Horizontal and Vertical Keystone correction along with 4 corner adjustment features eliminate crooked or distorted images for a perfectly proportioned picture every time.
