TROUBLESHOOTING
1. The BG-4KCH supports HDCP to protect legal content from copyright infringement. If an HDMI input
is eequipped with HDCP protection, the status LED will turn red to indicate the presence of HDCP. No
capture will be legally allowed if HDCP is detected. Please use non-HDCP protected HDMI sources or
disable HDCP in order to enable content capture. Check connected device for an option to disable
HDCP.
2. Due to the complexities of OS and computer hardware, different USB ports on your PC or laptop may
have different performance or limitations. If the device does not work on one USB connection it still
may work on another.
3. If video quality is low or the video connection is intermittent, try another HDMI cable.
