DV works fine on the TV's Netflix app, but when I go to use my Nvidia Shield through my Denon AV receiver there is no DV option available. The Denon is set to "enhanced 4K" HDMI signal and so is the TV. Any ideas where else to start troubleshooting with this? Highly doubt it's the cables because they are new and well regarded. Thanks

**update

It appears I have found the solution, albeit in typically frustrating fashion for this kind of thing, by trial and error. On my Sony TV the HDMI signal was set to enhanced Dolby Vision, but obviously wasn't working. I unchecked this option and checked only 4K enhanced, then went back and checked the Dolby Vision option again and viola, Dolby Vision appeared on my Shield. This stuff is insanely finicky sometimes, but hey, its working now. Thanks for all who tried to help me, much appreciated and the solution is now there for anyone else who runs into this
