I am using ADV7441A on our board.I have set ADV7441A in HDMI auto mode: PRIM_MODE[4:0] is set to 0x6 (HDMI-GR mode).


Using this mode, I can determine the input standard by reading the STDI registers and the HDMI synchronization parameters registers from the HDMI Map.


The refresh rate is not updated in any of the status registers.


How can I determine the refresh rate of input video in HDMI-GR mode of ADV7441A?
