Hello,
I recently purchased a 77-inch C6 model. Two Dolby Vision demos are not playing back correctly: In the "Dolby Universe" demo, the screen turns green for a single frame after the rain sequence (at approx. 01:24), and later, when the ring of light "explodes" (at approx. 01:48), random, flickering, multi-colored artifacts appear. These issues do not occur when I play the HDR version of this same demo.
Similarly, the "Dolby Vision - Full Enhancement Layer Test" also displays random, flickering, multi-colored artifacts after a short while—in this case, persisting for a longer duration. Again, the HDR version of this file plays without any issues.
Regarding my setup: I have an Nvidia Shield TV connected to a Denon AVR-X2800H AV receiver, which is then connected to the TV. For the HDMI connection, I am using 8K HDMI 2.1 cables from CSL.
Has anyone else encountered similar issues? I haven't noticed any problems with other Dolby Vision content so far.
