Connects MACBOOK with ADV7619, the display is abnormal

our customer Hikvision uses ADV7619 to recieve the HDMI signal from MACBOOK, and can't display normally, only snow noise can be seen, but display well with other signal sources. customer thought the data should be encoded, the ADV7619 they purchased is without P version, should support HDCP function.


checked the register of 0x88 ( AKSV_UPDATE_X_RAW), the readback value is 0x0, does that mean there is AKSV updated on port A and B? 


what's the root cause for this issue? is it the wrong configuration on some registers?
