Installed my ATV4K last night. Ran into a recurring issue where the Dolby Vision badge randomly appears which causes a slight stutter in playback when listening to music. Sometimes the screen will go black during this. My tv is a 2017 LG C7. Playback selected is 4k DV at 60Hz. Anybody else experiencing this? The HDMI cable is a new high-speed Amazon cable with 18 Gbps capability. Use the same cables for Xbox One S and 4K DTV boxes.
