I have a UHD TV in my living room and a 1080p TV in my kitchen. I want to be able to mirror whatever is playing in the living room to the kitchen. Many of the newer receivers and processors have a 2nd zone HDMI output. The question is, can any of these receivers down-convert HDCP 2.2 4k content for display on an HDCP 1.4 1080p television in the second zone without down-converting the signal sent to the main display? I have not been able to ascertain this by looking at the product literature. Do any of you folks know the answer?
