hi,

I am using the ADV7612-P and ADV7511 for converter a video signal.

But our board has some problems as below.

Please check and recommend which register we should control.

As you can see, the ICON,the left vertical line has a green shadow like Red Box.

Input : PC

Resolution : 1080p 60Hz (when we tried to test other resolution, the issue also is occurred as below picture.)

Output : HP TV (other Monitor and TV also have a same issue so we think this is not sink problem.)

Here is our system block diagram in the HDMI side.

HDMI In ------------------------------------------------------------------ HDMI Out

YCbCr 4:2:2 20Bit

 

We used the serial resisters 33ohm between HDMI TTL output and TTL input

Could you please help me?

I will wait your comment.

  1. Thanks.

Jun,
