I am sure this is not the first thread about the issue how MS handles the hotplug detect. I.e. when you switch off the receiver, displays get messed up. I used the trick to block pin 19 (hotplug). That kind of helps. However, I have now the issue that I get HDCP errors every so often. Does anyone know if pin 19 is involved with HDCP negotiation?
What is the protocol on pin 19? Just +5V or so or a real communication protocol?
