Hopefully someone can give me detailed instructions to set up the ROKU ULTRA to my AVR. I have the following equipment: TV: Samsung UN55C6900 from 2010 I think AVR: Denon X1300 STB: Scientific Atlantia 4250HD Optical to TV from AVR (I am using external speakers) All others connected via HDMI Not using ARC Harmony 650 remote
While the Roku and your AVR are both 4K/HDR compatible, the TV is not. So it really shouldn't matter if you connect the Roku directly to the TV or to the AVR. I suggest just connecting via HDMI to your AVR, since it will support Dolby Digital +, and it's highly unlikely your TV would. Many of the online streaming sites use DD+, so it's best to have your audio device support it.
