PS4 + HDR + TV that supports HDR / Receiver doesn't
The new PS4 firmware update 4.0 adds HDR capability to even the current PS4s (like the one I have). It's currently connected to my Pioneer Elite SC-85 (doesn't support HDR) which is connected to my LG 65EG9600 (which supports it over USB and HDMI -- in the firmware version I have -- UB).
I also have a Samsung UBD-K8500 UHD / 4K disc player en route (E-bay purchase) with which I'll want to take advantage of HDR. So I went ahead and ran a second HDMI cable through the wall directly to the back of the TV. Using the dual HDMI outs on the player, I can run one cable from the player to the receiver (for audio) and the one I already have in the wall (for video). Problem solved for the Samsung 4K player... but what about the PS4?
If I want to take advantage of the PS4's new HDR capability, I'd need to run ANOTHER HDMI cable through the wall (it's a pain in the ass... and it's getting crowded)... but then would have to feed the audio back via ARC... at which point, if I recall correctly, I would lose lossless audio, correct? Probably not a big deal since I'll do my movie watching via the Samsung, but... is there an easier way?
I have an ATMOS capable receiver (and speakers in place to support it), so I'll definitely want to keep the audio lossless for the 4K player... just wondering if there is an easier way to do this for the PS4?
