With output of Denon connected to FrameHDMI 3, upon powering on Denon, my six month old Frame 85 fails to properly sync video from any Denon input (TiVo / Chromecast / Apple TV).. I see a couple of snowy attempts to sync video then get the blue screen saying to check Source.
As a workaround, I can bring up the Denon Settings UI (1920x1080/60p) which the Frame will sync properly, then dismiss it and return to the AVR output (720x480/60p Input Signal Plus) and it will now sync properly.
Tried a bunch of different HDMI cables, endless settings options in Denon with respect to up scaling, HMDI output, etc. but it always ends up being this same behavior — basically the Frame seems unable to sync 720x480/60p until it has first been synced with 1920x1089/60p
