Hi


I am working with the ADV7623

 

Currently using same EDID setup as evaluation board.

For register setup i am using:

:1-3 Port A Audio Pass Through Mode for 192KHz multi-channel PCM: 

 

and :6-1 EDID Download HDMI: (but with same EDID settings as evaluation board.

 

I have a few problems: 

Some sources dont get through, such as the blu-ray player we have here.

 

Image quality on our Epson EB-G5450WU is very poor. Looks like noise but also happens with very short cables.

(see attached images).

 

Currently I am not 100% sure if this is a software problem or if it could be a hardware problems.

I lean towards software realted. 

 

Any ideas how i might move forward?
