Most EDID issues are the result of the way manufacturers are implementing this communication. It is a file that is dumped out of a separate location, not even in the processor. This happens only once and there is no communication back on forth been the send and receive devices should the EDID communication be missed or misinterpreted by either device.
The very smart folks at KDS inform us at CEDIA that with THEIR cables will work at lengths of to 75 feet without issues. I was supposed to have tested this but like everything else in my life I am a bit late. Perhaps this weekend. I have heard that HDCP has been problematic at distances over 40 feet.
