I recently bought a Sony A80J TV and upgraded from Sky HD Plus to Sky Q UHD. I've noticed when using the YouTube app on the Sky Q box that the picture has a slight stutter on some videos but not others. Has anybody else experienced this?
Sky Q does not match the native frame rate of video played via its apps, so it’s always better to use the apps built into the TV which usually will.
The alternative is to turn on judder reduction for apps on your Q box. This will output at 60Hz rather than 50Hz which can help.
