Overview
A living room with little space behind the couch is where this compact projector fits. Its short throw lens fills a large wall from a few feet away, and a laser light source replaces a lamp that needs changing.
Brightness holds up in rooms with the lights on, and the laser source needs no maintenance over its stated hours. The picture is full HD with 4K HDR accepted as input, and no streaming apps are listed.
Who it's for
A gamer or movie fan who wants a large picture from a short distance without a darkened room. People who want native 4K or an app platform in the projector itself should choose differently.
Pros and cons
- Bright output for lit rooms
- Short throw for tight spaces
- Laser source with long rated life
- Game mode listed
- Native resolution is full HD only
- No streaming apps listed
- Speaker details not listed
- Fan noise not listed
Performance notes
Laser light gives steady brightness without lamp wear, and the short throw lens trades distance for a wide image. HDR input is accepted, but the panel is full HD, so the picture is not true 4K. The listing cites a faster game mode, with response figures unlisted.
