I have been using a Yamaha RXV481 for a couple years with no issues. I just got a PS4 Pro and I keep getting "No signal". I finally went into safe mode and changed the resolution to 1080p. I have a Sony 4k HDR UHD TV. When I connect directly to the TV there are no issues with PS4. Any suggestions on how to get the PS4 UHD/ 4k content to play thru the receiver? I appreciate any suggestions.
