ADV7842-- HDMI Free-Run mode, how to set customized video standards?

On my system, HDMI input will be connected to the signal with the following resolutions:

480i/480p/720p/1080i

There are two cases that free run will need to be triggered:

1) the cable is not connected initially

2) the cable is unplugged

 

In case 2, the free run mode works fine since it already knows what's the resolution that I expected.

but for case 1, since there is no any context available, the free run mode will based on PRIM_MODE[3:0] and VID_STD[5:0]

to output predefined resolutions.

But since in my settings PRIM_MODE[3:0] is set to 0x6 (HDMI_GR), the output resolutions defined by VID_STD are only

graphic resolutions. based on the document, "for video standards other than the preprogrammed settings of PRIM_MODE and VID_STD, the

parameters can be set manually".

 

Can anyone kindly provide me the proper settings in my case? I will need all settings for the required resolutions.

 

Thanks.
