[Master Thread] - 4K / 2160p Juddering Issues - Sky/BT

[palmeri8145]

Hi all - thanks for all the informative information I have found on this community site.

I have recently purchased the above tv and I am using it with a (UK) BT Ultra HD package. The output of the box is 2160p50 and I have set it to 10 bit colour.

Generally speaking I am very happy with the telly but I am experiencing a bug which sounds similar to the "Screen Format: Full" issue reported on another thread.

After a period of watching TV (normally longer extended periods of say 2 hours), the picture starts to judder and the "Screen Format: Full" message flicks on and off. The only way to recover this is to switch the telly off and on again which seems to allow the telly to "resync". This problem happens *every* day when watching TV at least once.

It is not a problem with the BT box as when I switch that on and off the picture problem does not clear.

I have tried different 4K related settings on the telly / BT box but the problem still occurs. Has anyone else noticed this with the TV ?

Thanks,

Ian

Hi @petsmart

USA and some part of ASIA has a new firmware since yesterday. It is PKG3.531.0108.

I don't know if it is the same with EU and UK v3.509 but what I read is that:

• Improves general performance of the TV
• Reduce input lag for HDR game (Applicable only for 4K HDR models: X85C, S85C, X90C, X93C and X94C)

Japan except above, also has an Amazon improvement.

We wait for a few days and see ......

Here is a post from US forum:

"Well, its not listed in the patch notes, but it appears the Amazon app has been improved.

Finally supports Dolby 5.1, and the overall menu movement is smoother."

Hi @Risc0n

I think this remains 5.1.1 unfortunately.

Dear All

The Lastest:

Sony believes that they have identified and fixed the issue and as such a new firmware update is currently in testing.  Sony hopes to roll out this new firmware around mid-November.

Thank you all for your continued patience.

Hi all,

Looks like Sony has updated their support page with a patch:

"We’re pleased to announce that a new firmware update will be available on the 7th November 2016, for customers that may still be experiencing intermittent juddering while watching 4K content via a UHD set-top box.

To further improve stability and reduce the likelihood of juddering occurring, when it’s available, please download the firmware from our support site

We thank you for your patience and sincerely apologise for any inconvenience this issue has caused."

Seems to read like another USB update and I'm not liking the wording 'reduce' instead of 'fix'
