I'm in the same boat as you, playing PS4, having to use Lossy DTS or Dolby because LPCM .....
Just out of curiosity : why did you choose dolby over dts ?
Thank you.
My understanding was that the Q80T doesn't support DTS passthrough... I could be wrong I could also be wrong in that the setting influences the output.
I still can't figure out if it's actually Dolby 5.1.. yes I have sounds in the rears.. but how do I KNOW it's real Dolby and not some virtual surround that's being manipulated by the soundbar.
