Hi all,

 

we are using ADV7611 in our product. we dnot have EVM board.

input = 1080p@60

output = 1080p@60 RGB out

 

Below are my configuration

0x4c 0x06 0xa1  #Invert clock polarity all negative

 

0x4c 0x15 0x00

 

Input image top portion of scan image is perfect curve but output image top curve is not sharp.

 

Kindly give suggestion for us,
