ViewSonic LS921WU Short Throw Laser Projector

The ViewSonic LS921WU is a WUXGA short throw installation projector designed to deliver a high-quality visual experience in various environments, from conference rooms to home entertainment spaces. With its cutting-edge technology and advanced features, this projector is suitable for those seeking high image quality and flexible installation.

Image Quality and Performance

The LS921WU shines with its 6000 ANSI lumens brightness, ensuring vivid images even in well-lit rooms. Its native WUXGA (1920x1200) resolution ensures remarkable image clarity, while the 3,000,000:1 dynamic contrast ratio delivers deep blacks and brilliant whites, enhancing the overall visual experience.

ViewSonic’s SuperColor technology offers a wide color gamut, ensuring more true-to-life color performance in both bright and dark environments. Moreover, the 2nd generation laser phosphor technology extends the light source’s lifespan up to 20,000 hours, reducing maintenance needs and long-term costs.

Installation Flexibility

The LS921WU is designed for flexible and convenient installation. Its short throw ratio (0.81-0.89) allows for large image projection from a short distance, minimizing shadows and glare. The 360° projection and portrait mode offer exceptional adaptability, enabling projection on ceilings, walls, or angled panels.

The wide H/V lens shift and 1.1x optical zoom make image adjustment easy, while the horizontal and vertical keystone correction and corner adjustment functions ensure a perfectly proportioned image regardless of the projection angle.

Connectivity and Management

The LS921WU features two HDMI 2.0b ports supporting 4K HDR/HLG content, offering maximum flexibility for connecting various devices. The built-in HDBaseT enables efficient transmission of video and audio signals over long distances, simplifying installation and reducing cable clutter.

Usage

The LS921WU is designed for 24/7 continuous operation, thanks to its advanced cooling design and IP5X sealed optical engine, which protects it from dust and ensures consistent performance over long periods. Remote management of the projector is facilitated by compatibility with Crestron, AMX, PJLink, ATEN, Extron, and ViewSonic’s vController, allowing IT administrators to monitor, schedule, and manage the projector remotely.

The advanced sealed optical block prevents dust from entering the video projector and affecting the thermal system to ensure the image quality is maintained and has a long lifespan.
