BZBGEAR BG-4KCHA PRODUCT MANUAL
Introduction
The BG-4KCHA is an advanced USB-C 4K video capture device with a scaler, HDMI 2.0
loopout, audio, and HDR10 to SDR conversion, designed for professional HDMI video
signal capturing. It uses a USB 3.1 Type-C Gen 1 (USB 3.0) interface, allowing for
high-speed transmission. Additionally, the HDMI input and loopout can support up to
4K2K@60, enabling users to connect the BG-4KCHA to a 4K@60 source and capture Ultra
HD (4K2K@30) video. With the capability to capture and display uncompressed HDMI
video, the BG-4KCHA provides more realistic color renditions. Moreover, the BG-4KCHA
employs large volume image buffer technology to effectively avoid video tearing, while the
high sampling rate and accuracy result in captured videos with high sharpness, rich details,
and fewer color edges.
Furthermore, the HDR10 to SDR conversion allows Playstation and Xbox players to enjoy
4K2K@60 HDR games on a 4K TV through the loopout HDMI port and record real-time
4K2K@30/1080P@120 video streams with SDR quality through the USB 3.0 port
simultaneously. With its versatility and features, the BG-4KCHA is a highly capable and
professional-grade HDMI video capture device for demanding applications.
