I am using the ADV7619 receiving HDMI video on port B only. The problem is when I disconnect an HDMI cable the RXB_5V does not go below 2.5V. This is causing the port to always indicate there is a cable connected to this port even though it is not. Is there a register that needs to be set to bring it down to zero when the cable is disconnected? When I power up with no HDMI cable it goes to zero although I do see it rise to 2.5V for a slight time and then drops to zero.
