Can we turn off EDID internal/external in ADV 7842? My device is not used for display but used for decoding DVI data for further processing. But still the DVI tx can assume that it is a display and ask for EDID correct? Is EDID mandatory for the decoder for DVI video sources? And if we are using an HDCP enabled part can it process non HDCP signals too? If we are using a non HDCP part and later migrating to an HDCP part then are any software changes required? Thanks in advance.
