Overview
A living room wall or a bedroom ceiling becomes a cinema screen when this compact Google TV projector is set up on a table or the floor. A hybrid LED and laser source drives a native 4K image, and HybridBeam and keystone correction square up the picture.
Streaming apps, Dolby Vision and a bright image make it a one-box movie setup for a dim room or an office presentation. The listed contrast ratio is modest, so blacks look gray, and lights on during the day wash out the picture.
Who it's for
A renter or home theater beginner who wants a big picture without a TV, and a streaming platform that needs no stick. Gamers can connect a console by HDMI. Anyone who needs outdoor use in daylight should look for a brighter model.
Pros and cons
- Native 4K image
- Bright hybrid light source
- Google TV built in
- Wide image size range
- Low contrast ratio
- No battery listed
- Lens shift not listed
- Warranty period unclear
Performance notes
Brightness sets how well the picture holds up with room light, while contrast sets how deep blacks look, and the contrast figure here is modest. The mixed light source gives strong brightness and color for a portable unit. Keystone correction squares an angled image but trims some sharpness.
