What sets the BenQ LK935 4K Ultra HD Laser DLP Projector apart is its ability to deliver an immersive and engaging meeting experience. With its high 4K resolution and 5500 lumen brightness, this laser projector ensures superior image quality and clarity, even in brightly lit environments or during video conferences with multiple split screens.
The 4K UHD high resolution of the LK935 projector surpasses the image quality of WUXGA, providing sharper and more detailed images. This is particularly beneficial during video conferences, where the 21:9 aspect ratio and Video Conference Mode automatically optimize the accuracy of skin tone depiction for a more immersive meeting experience.
The LK935 projector's wide 1.36-2.18 throw ratio allows for a display of up to 200 inches from 6 meters, providing a large and clear view of all relevant information. This, coupled with a large lens shift and a big 1.6X zoom, offers flexibility in installation and positioning.
The high contrast DLP technology of the LK935 projector ensures clear detail against both light and dark backgrounds, outperforming 3LCD projectors. The 5500 lumens and laser-driven high brightness ensure that your presentations remain clear and visible, even in bright ambient lighting conditions.
The LK935 projector also features a picture mode tailored for video conferencing. This adjusts skin tones for a natural and immersive presentation, eliminating washed-out or unnatural-looking skin tones during video calls. The 21:9 aspect ratio enhances virtual meetings, making face-to-face communication more lifelike.
The LK935 projector offers flexible installation options, including H/V lens shift for mounting flexibility, 1.6x zoom for easy upgrades and installation, and 360-degree rotation projection. It also features a 3D keystone for ideal projection alignment, countering the trapezoid effect that occurs when a projector is installed off-center.
The LK935 projector supports high system integration and compatibility, with HDBaseT for uncompressed transmission and control, and compatibility with leading projector control systems such as Extron, Crestron, and PJ-Link. It also supports RS-232 for reliable long-distance installations of up to 15 meters.
The BenQ LK935 laser projector is designed for high reliability and low maintenance. It offers 20,000-hour long-lasting performance, DustGuard technology for severe conditions, and filter-free DLP technology for lasting vibrant color.
