A portable 4K laser projector whose single HDMI 2.0b input is its main connectivity limitation — with only one wired video port, switching between a console and a streaming device means swapping cables or using an external switch. A powered USB-A 2.0 port handles a streaming dongle or media playback, and a 3.5mm aux output sends audio to wired headphones or speakers, while Bluetooth 5.0 covers wireless. There is no optical output and no Ethernet, so audio to an AVR relies on the HDMI source or the 3.5mm jack. The unit powers from an included AC adapter.
Portable 4K laser projector with a single HDMI 2.0b input, one powered USB-A 2.0 port, and a 3.5mm aux audio out. No optical or Ethernet.
