ADV7611 question

My customer has this question:

I have an ADV7611 HDMI receiver that feeds into a GS2972 SDI serializer.  The HDMI input can be 1080P or 720P and the frequencies can be 24Hz, 25Hz, 30Hz, 50Hz, 60Hz.  Are there register values that need to change in the ADV7611 to support these different resolutions and frequencies or is it automatically detected?   If it is automatic is there a way to detect changes when they happen since I believe the GS2972 will need to be  configured differently?
