I used the section 6_4b of the register setting of the ADV7612-VER.2.9c.txt
(from your EngineerZone) and its EDID register setting for the ADV7612 and
verified that the port A of the ADV7612 in our system works. The port B of the
ADV7612 in our system is connected to a Displayport-to-HDMI conversion chip.
The Displayport does not work. There is possibility that the port B of the
ADV7612 is not setup correctly.
The only difference in the register setting from selecting the port A to
selecting port B is:
For the port A: 68 00 08 ; Set HDMI Port A
For the port B: 68 00 01 ; Set HDMI Port B
Is this right? Do I need to do anything else?
