My TV is the LG B19LA.
I checked with match framerate on with the diagnostic feature for vrr (green button spam) that the actual framerate ist used. It shows 24hz for example in watching dolby vision content.
The TV has to tell which delay it is producing to display the picture in difference to the sound. And this is for my understandings not happening.
Thats the tv side with hdmi 2.0b and above.
So for auto lip sync to work the delay the avr has to set is not provided.
I want to clarify that this delay is only getting worse with match framerate active. It makes it unwatchable.
If i dont use this feature there is still a slight delay which for sure can be adjusted.
BUT: This is the problem here. The whole reason to buy a apple tv is for using this framerate feature to get the original material.
After switching the avr from 3600h to 3700h not affecting anything. Changing the apple tv to a new device not affecting anything i really think its the tv.
Why is this not happening on Amazon Fire TV? This is a funny thing. This device has also a match framerate option. But on netflix for example its not beeing used.
The lg always tells me the 50hz content. Even if it works: The fire tv has his own setting to align picture with sound. There is a bar so can slide to adjust this.
So the delay is preadjusted.
The apple tv device doesnt have this feature.
Since the apple tv cannot adjust anything the tv has to do this. And its not doing it.
If you processor of your tv is slow the delay gets worse. Just logical. The b1 is the slowest processor of the 2021 lineup.
And when this LG is not telling any delay to the avr this is just unfixable.
This is why i generated a warranty request. This request comes to an present meeting where the technician change the whole board of this tv.
This again doesnt affect anything. The request comes to a second request and lg tells me that the part which is needed to switch is not available.
What part is a mystery for me.
Now i have the chance to refund this tv.
I have to go to another lg because theres no other tv on the market (at least in this price range, sony costs around the double) with the features i need.
I hope the new one will work. Till today i cant find any problems on any forum with the 2022 lineup which makes me a little hopeful that the horror story comes to an end.
If this is not fixing it well than i have to ask if any human on the planet have their brains defect and cannot see the issue here.
Sorry my english is not the best on the planet
