4K HDMI to USB 2.0 Capture Adapter

This adapter captures 4K video input at 60 Hz and outputs up to 1920x1080 at 30 Hz over USB 2.0. It records both audio and video simultaneously for live streaming, teaching, gaming or video conferencing. The plug-and-play design requires no driver installation or external power. It suits creators and professionals who need a simple capture solution.

Sustained capture with ultra-low latency

The nano-metal HDMI interface delivers ultra-low latency during extended sessions. Video and audio are captured together and streamed directly to a computer or smartphone without noticeable delay. OBS and similar software receive a stable feed for long broadcasts or recordings. The aluminium-alloy shell aids heat dissipation during continuous use.

Upgrades from basic screen mirroring

This device replaces simple screen-mirroring dongles that cannot record or stream independently. It adds simultaneous audio-video capture and direct file saving for archiving or post-production. The jump is worthwhile when you need reliable 4K input capture at 60 Hz with 1080p output for live production. It is not for users who only need passive display output.
