Sony 43X8000H "judder"

Looking for feedback/opinions on the video below I made of the F1 on Kayo's app on a new Sony 43X8000H TV.

Vid was taken on an iPad Pro in slo-mo.

Looks a bit like it is converting a 50Hz source to a 60Hz screen rate. 5 frames then a repeat frame.

I'd say it is just the Kayo app not being particularly clever, and is not able to switch to 50Hz.

My thoughts exactly!

Sadly it's not limited to the Kayo app though -- I can reproduce the judder with the TV's "Chromecast Built-in", and by playing anything recorded at 50fps from a usb drive.

None of the refresh-rate apps I've tried helped, as it would seem the TV's OS is "locked" to 60Hz.

If I plug a laptop in I can select all the usual combinations of resolution/refresh-rates including 50Hz options.

If "Chromecast Built-in" is based on an old version of Chromecast, that would be consistent with complaints I've seen regarding 50/60Hz judder.
