Packed with 4,000 ANSI Lumens, the projector is guaranteed to produce high brightness suitable for well-lit environments.
USB Type-C for Direct Streaming and Recharging
The projector’s USB Type-C* connection puts a fun twist on streaming videos by allowing you to project content directly from your phone, laptop or tablet while also charging them simultaneously. You can even play Nintendo® Switch games on the big screen via direct connection without the dock.
*Only available for devices that support USB Type-C video streaming.
*For iPhone and iPad, users need to buy an Apple-authorized Lightning-to-HDMI adapter for content display via the HDMI port.

Effortless Image Adjustment
Be it on the side table in the living room, bedroom or any other location you like, the projector can provide perfectly shaped images from any angle with comprehensive H/V keystone and 4 corner adjustment capabilities. The auto V keystone further frees you from manual adjustments no matter how you tilt the projector, up or down.

Reliable Long-Term LifespanThe latest SuperEco+ mode technology greatly extends the lamp life of the projector from 15,000 hours to 20,000 hours – meaning 4 hours a day for more than 13 years – saving you maintenance cost and effort.
USB Type-A Power Supply for HDMI Wireless DonglesA built-in USB power output (5V/1.5A) can be used to supply power to HDMI wireless dongles, like Chromecast, Amazon Fire TV Stick, etc., eliminating the need for separate power adapters when streaming your favorite multimedia content.
SuperColor™ TechnologyViewSonic’s proprietary SuperColor™ Technology displays a wide color range, ensuring that users enjoy a true-to-life color performance in both bright and dark environments without sacrificing image quality.
Satisfying Audio PerformanceThe projector is embedded with a 10W speaker to deliver a satisfying audio performance right out of the box.
A More Eye-Friendly Viewing ExperienceUtilizing reflective light, which bounces off the wall or projector screen before hitting your eyes, the projector makes the viewing experience virtually blue light free, less invasive to your sight, and reduces eyestrain over prolonged viewing periods.
