Dolby Vision always interrupting my LG TV

My new LG doesn’t seem to get along with my Denon AVR S770H receiver. Dolby Vision problem with Denon and LG C5 Television, I don’t know if it’s the LG or Denon’s fault.  When Sirius is playing it always interrupts 1 second with a black screen and no sound at the same time the TV screen flashes Dolby Vision in upper right corner.  It’s just as bad when I’m watching a ball game when the screen goes from the batters hit, flashes to the outfield shot.  Anyone have any advice how to solve this?
