Hi,

 

I have some HPD problem with ADV7604 DVI input.I have two issues,plase help.

1,Because ADV7604 has no HPD pin,we want to use a mcu to control it.The mcu GPIO will sent a pulse to HPD(low to high) it is OK?

2,If we need two eeproms to realize EDID function?  In ADV7604 evaluation board, what's the function of U18? Now we just use U10.
