Troubleshooting
Usually, if the system seems not to transport the signal as expected, the best
strategy for troubleshooting is to check signal integrity through the whole
signal chain starting from source side and moving forward to receiver end.
General Problems – Check the Device
Check whether the DA2DVI-HDCP-Pro is properly powered and one
of the Power LED is green. Try performing a reset by unplugging and
reconnecting the power adaptor.
