Help configuring Roku device settings, using Roku OS features such as screen mirroring, adjusting display type and audio settings, using Guest Mode, and assistance with software updates.
I have a native 4k projector and high home theater sound system. I am using the Roku 4661r does the new 4800r offer my any noticeable improvements in HDR 10 or Atmos sound. Or is there another reason to upgrade
