Just got this TV yesterday. using it as a monitor. Just double checking... I have my PC connected to the TV, then the eARC to my Q90r soundbar. Dolby atmos is set up on PC. "Sound out" is set to HDMI ARC. I have eARC selected and "Digital sound out" set to Pass through. But in "HDMI Input Audio Format" do i select PCM or Bitstream for the HDMI slot my pc is connected to?
