Connected to a computer’s USB 3.0 port, this single-input capture box records or streams an HDMI source at up to 1080p while passing the original signal, up to 4K60 with HDR, through to a local display. 4K sources are scaled down to 1080p for capture automatically. Stereo audio is taken from either the HDMI signal or the 3.5mm analogue input.
