True 4K Clarity with HDR/HLG Support
In addition to the stunningly detailed images that true 4K resolution can offer, the projector also supports HDR and HLG content to produce more dynamic images and bring flat images to life with more displayable information in the darker and brighter parts of a scene.
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.
Perfect Projection Even on Curved Surfaces
Who says projection only works on a flat surface? With our advanced Projector Warping Tool, the distorted image can be perfectly shaped through multiple point adjustments, even when projected on spherical or cylindrical shapes.
Customize Your Own Color Profiles
By using a cloud-based color profile exchange, users can create their own color profile to fit their preferences and share it with others. Also, users can download other profiles from their projectors and fine-tune them as their own.
Reliable Long-Term Lifespan
The 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 Dongles
A 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.
