Have an install with two rooms of 4K Directv, Sony ES AVR's (5000, 2100), Sony A9F TV's. We're having an issue with the DTV setup. Things work fine watching and changing channels, in and out of 4K etc., until turning the systems off (either system). When you turn either system on and try the 4K channel the DTV has a pop up that says "Your TV doesn't support 4K content. You are watching it in 1080p, the highest resolution available". We've tried changing the order each device turns on, etc. with no luck. The one thing that does seem consistent is when you turn off each device (TV, DTV, AVR) by itself then back on the only one that "triggers" the DTV 4K message is the Sony ES AVR, consistently. We tried changing to HDMI output 2, etc. BUT, one thing that "seems" to be working in turning on Zone 2 (even though we aren't using it for anything). It was late but I accidentally turned on Z2 and noticed when I left it on the message didn't pop up when testing. I tried about five times. We left Z2 on for now and we'll do more testing tomorrow. Another weird thing is we are having some trouble with both AVR's consistently getting on and off commands. We're using ip control. We've used the ES with ip control before without any issues. Still playing with delays, etc on this issue. It may or may not be related. Also, for what it's worth we tried a Yamaha Aventage 1050 (few years old) and it didn't cause the 4k pop up message after trying about ten times. Any ideas would be greatly appreciated.
