ADV7619 VSYNC frequency - possible to tweak?

hi,

 

i am using adv7619 to receive HDMI 1920x1080 p60/p50/i60/i50 and output YCrCb 10bit format to the next stage.

 

on the VS signal, the signal is measured to be 59.84Hz for p60/i60.

 

1.on the next stage monitor, for i60 the output display is detected properly, while for p60, the image is not detected properly and monitor says "over range".

 

2. on a frame grabber card on a pc, again i60 image can be detected properly, while for p60, the image is detected instead as p30 not p60, and there is no proper image captured.

 

i am wondering if there are any settings on adv7619 that can influence the output VS frequency ? 

 

many thanks !
