The LW820ST WXGA 3600-Lumen Short-Throw Laser Projector from BenQ uses BlueCore Laser technology to deliver high colour performance. It has a brightness of 3600 ANSI lumens and a contrast ratio of 100,000:1. This projector has a manual focus lens that supports a throw ratio of 0.52:1.
This projector features two HDMI ports (one with MHL), two VGA inputs, RCA composite, and S-video inputs. There are 3.5mm audio input and output jacks along with a 10W built-in speaker. A 9.8' power cord, remote controls, two AAA batteries, and a 5.9' VGA cable are included. A wireless display, PW02/PT12 interactive module, and dust filter are available separately.
- BlueCore laser technology with precision-aligned, high-output laser source, secondary yellow-infused colour wheel, and hermetically sealed DLP chip
- DustGuard technology includes sealed laser modules to protect the laser bank
- Colour wheel sensors have anti-dust accumulation that resists dust buildup
- Dual-colour wheel system produces high colour performance by increasing colour ratios and purity of RGBY colours
- 3600 ANSI lumens provides brightness efficiency at the same level as IFPs for clear, sharp images and text even in large, bright classrooms
- Custom brightness function allows manual light output adjustments in 1% increments
- Creates clear images with a 100,000:1 high contrast ratio for true deep blacks
- Instant power on and off to reduce setup time
- 20,000 hours of maintenance-free operation
- The big screen in short distances with a 0.52:1 short-throw ratio eliminates distracting shadows and glare for students and teachers to engage and collaborate in front of the board
- Range of resolutions and projected image sizes to meet diverse classroom needs
- PointWrite interactive module PW40U and QWrite software (available separately) provide truly collaborative learning environments where students and teachers work together using intuitive templates
- Using QCast or Instashow accessories (available separately), teachers and students can bring their own smart devices and computers to stream documents, images, and Full HD videos to this projector
- Compatible with leading projector control systems including Crestron, AMX, PJ Link, and Extron IP Link for network control via LAN
- Multiple Display Administrator (MDA) software enables powerful centralized monitoring, control, and power scheduling across the school's projector network from a single computer
- Administrators can centrally upgrade the firmware on multiple networked BenQ education projectors on the same local network via LAN (up to 253 projectors), deploying the latest updates to all devices at once
- 0.75x digital shrink is used for fine-tuning the screen size via the OSD menu when the image is not precisely aligned on the desired frame
- The remote control's quick install hotkey sets up the projector with significant time savings for managers performing initial projector installation work
- DLP-optimized optical lens systems provide precise readability and resolution for every sub-pixel
- IR receiver on front and top
