OVERVIEW

The LS741HD is part of ViewSonic’s Luminous Superior Series, a lamp-free projector lineup designed for commercial and educational spaces. It can project up to a 300” ultra-large screen in 1080p Full HD resolution with high native contrast. This DLP projector uses 3rd generation laser phosphor technology, delivering a brightness of 5, 000 ANSI Lumens for up to 30, 000 hours. Its lamp-free design offers an eco-friendly and cost-effective solution with less power consumption, while its lightweight and compact build reduces transportation costs. Equipped with features like a 1.6x optical zoom, H/V keystone, and 360° projection capabilities, the LS741HD offers flexible setup possibilities. Additionally, its comprehensive LAN control allows centralized management, making it perfect for boardrooms, lecture halls, and public spaces.

Bright, Compact, Durable

The LS741HD incorporates advanced 3rd-gen laser phosphor technology, enhancing brightness by 20% and achieving better luminous efficiency, all while being 32% more compact and more accessible than the previous generation. Its lamp-free light source offers instant power on/off and a lifespan of up to 30, 000 hours without maintenance, ensuring consistent image quality even during extended periods of use.

Bright Images for Large Venues

Delivering 5, 000 ANSI Lumens, the LS741HD provides vibrant and sharp projection in 1080p FHD in all lighting conditions for gallery, restaurant, gym, and other expansive spaces.

Save on Costs and Energy

With its advanced lamp-free light source, the LS741HD offers a highly energy-efficient and cost-saving display solution by consuming up to 51% less power than competing projectors.

Unmatched Contrasts, Enhanced Visibility

This projector utilizes the advanced 0.65" DMD chip from Texas Instruments, surpassing the capabilities of the 0.47” standard chip. It offers a high native contrast ratio for deeper blacks, resulting in clearer, more legible images with enhanced visual depth.

Enhanced Installation Flexibility

Equipped with a 1.6x optical zoom, 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. ​

Centralized Control for Management Efficiency

The LS741HD is compatible with Crestron, AMX, PJ Link, ATEN, and Extron systems, allowing for centralized device management for better operational efficiency​.

Easy and Cost-effective Installation

The LS741HD is 33% lighter in weight and 32% smaller in size compared to its predecessor and even most competing projectors in the market, greatly reducing the cost of transportation and increasing the ease of installation. ​

Ultra-large Screen with Lower Cost-per-inch

This easy-to-install projector allows for an image size of up to 300”, offering a lower cost-per-inch compared to other types of commercial displays. ​

Upgrade Your Projector with Wireless Content Casting

Enhance your projector with the WPD-700 Wireless Screen Casting Kit for seamless wireless content sharing. The projector's built-in 5V/1.5A USB-A output powers the dongle, enabling simultaneous multimedia streaming and power charging without adapters.

Get ​​Perfectly-shaped Images Effortlessly

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

Improved Dust Resistance for Enhanced Durability

This DLP projector's innovative sealed engine, rated IP6X, prevents dust from affecting internal components without using an air filter. It ensures longer product life and consistent image quality, even in environments with poor air quality, saving on maintenance costs and efforts.

Versatile Creative Application​s

The projector can rotate vertically at any angle, enabling projection onto ceilings, walls, or floors, and its portrait mode further expands its capabilities for projection mapping, staging, and creative advertising applications.

Non-stop 24/7 Operation

The projector's advanced cooling design enables 24/7 operation without any degradation in image quality or performance. This makes it the go-to solution for applications that require continuous projection in retail stores, malls, museums, airports, and other public spaces.

A Simpler Way to Update Projector Software

Skip trips to the service center by keeping software up to date easily via USB cable connection with your own laptop.
