Key features
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.
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.
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.
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.
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.
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.
The LS741HD is compatible with Crestron, AMX, PJ Link, ATEN, and Extron systems, allowing for centralized device management for better operational efficiency.
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.
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.
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.
Horizontal and Vertical Keystone correction along with 4 corner adjustment features eliminate crooked or distorted images for a perfectly proportioned picture every time.
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.
