Every time I see people bring up using ARC it is because they are having a problem with it and the general consensus seems to be "Stop using it."
^ yeah, what he said.
HDMI-ARC is limited to DD and PCM 2.0, and in teh case of my Samsung TV, it has problems transcoding DD+ to DD which should be a breeze. So....
The 775 supports 4k passthrough at, um, 30, 25, 24 fps or so? Check your manual. A later revision of the 4k UHD standard upped the frame rate to 60 fps, in HDCP 2.2 IIRC, and that was finally incorporated with the 779. So ... the answer is, it depends. Older 4k stuff will work fine, but newer 4k stuff will not pass through properly. Kind of a bummer for those of us who thought we were future-proofing our hi-fis.
Like m.zilch, I don't 4k-anything, but I love the web, app features of the 775 -- I'm playing Crowded House from my NAS through the DLNA Server input now, controlling with the Yamaha AV Controller app on my iPad Mini that I'm writing on -- so I'm not too bummed.
