Equalizer setting for ADV7611


We use ADV7611, in our project recently we found that HDMI input 1080p60 video will appear snowflake phenomenon, after repeated tests confirmed that it has something to do with chip EQ settings, but through the chip datasheet I do not know how to set EQ values to get the best results in different environments, our question is as follows:

a) What is the specific definition of 0x8D/0x8E two registers under the HDMI module? How much can you adjust the EQ equilibrium ability to a maximum when you want to set it to?

b) Does EQ adjustment work best in dynamic mode or static mode? How do I configure related registers in different modes?

C) Through the Register Settings Recommendations document, {0x68, 0x9D, 0x02} configuration is removed, and in the actual test found that when adjusting the 0x8D/0x8E value can not completely solve the snowflakebut when the 0x9D is set to 0x02, the snowflake disappears. what is the detailed definition of the 0x9D register under the HDMI module?

following is our register config:
