Hi Lin-
I think delay caused by DVI is the consequence, not the reason. The reason is lack of device authentication within 100 ms. HDCP 1.4 spec says “The HDCP Transmitter must not read the R0 ' value sooner than 100ms after writing Aksv”. It looks like problematic sources wait only minimum amount of time and then switch to DVI as the sink looks non-HDCP compliant to them.
Best,
Igor.
Clik here to view.
