Hi, GuenterL . Thank you for your quick response.
After my review of the setting of resisters, this problem heve been clear.
Then, another questions happen.
I have find the following Table in the datasheet of ADV7180.
-------------------------------------------------------
Table61. RANGE Function
Range Description
0 16≦Y≦235,16≦C/P≦240
1(default) 1≦Y≦254,1≦C/P≦254
-------------------------------------------------------
My questions.
Q1.
Does ADV7391 also have the same functions ?
Q2.
In the case of using ADV 7391 and ADV7180 together,like "ADV7180BCPZ -> FPGA -> ADV7391BCPZ".
If ADV7391 do not have these functions, should I adjust Y and C/P of ADV7180 ?
