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?
