1 Second Screen Flicker
After a few minutes of watching 4K content, it will flicker intermittently for about a second. Happens about every 5-8 minutes. Does not happen on HD content. Any ideas? My cable from the receiver to the TV is in the wall and I REALLY don't want to remove the TV mount to replace the cable. I did recently switch to 4:4:4. Any ideas?
Gear is below:
Sony 75940E
Denon AVRX-4300H
Apple TV 4K
MonoPrice certified HDMI
Thanks!
