My Vero 4k is connected to my Denon X4400H AVR which in turn is connected to my LG OLED C7.
For 1080p movies the video and audio are perfectly in sync without having to adjust it in the AVR.
However, for 4k HDR movies there seems to be a delay in the video signal processing on the AVR and I have to add a 75ms delay to the audio in Kodi for the movie. This happens for all 4k HDR movies.
I can’t use the AudioSync feature on my AVR as this would cause the 1080p movies to be out of sync. I’ve tried playing around with the “Auto” feature on the TV and AVR but it seems to be making things worse.
The thing is, I had a Marantz NR1608 sometime ago and no audio issues with 4k HDR content. It had no GUI-Overlay feature for 4k HDR, the Denon does and I think that’s what’s internally causing the additional delay. I wrote Denon about it, they told me to use the Game Mode on my TV (lol).
It would be nice if we could somehow add a default delay for 4k HDR files, so I don’t have to adjust it for every movie every time I watch one. My girlfriend is already overwhelmed with changing the input source on the TV to the Vero, I can’t explain to her how to adjust the audio delay every time and do that only for 4k HDR files.
