55 XH9005 frame stutter on all content

[DarrellBowen87]

This TV was Brilliant till the last update.

it is now not running any 60fps smooth and seems to be struggling with rendering images 4k content looking pixelated. This is definitely the tv and not my PS5 as my series X is showing the same problems. Also lots of stuttering watching sky. And all these problems since last tv. Please sony tell me this is a firmware problem. If not i will be returning the panel for a new 1

Hi,

Please perform a factory reset and check if the stuttering persists afterwards.

If so, please get in touch with Sony customer support.

Cheers

Thanks for reply Peter.

i have performed the factory reset with no luck.

it seems the problem is with things connected through hdmi. Like the tv cannot keep up with the data being sent to it. Things are smooth then i get a frame drop so it can ammend itself. Hard to explain just know it isnt as smooth as it was

Is that v6.0466 you're referring to?

Have you tried clearing the cache (under Device Preferences - Storage - Internal Shared Storage - Cached data) then restarting by holding power?

Hey DarrellBowen87, sorry didn't see this post earlier. Did you try the steps mentioned above?

[DarrellBowen87]

Hi Hannah,

Yes i have tried the methods mentioned.

it is slightly better. But there is still a slight judder. Its like occasionally the tv drops a frame. The flickering has stopped and been replaced with the frame drops. 
it happens with my hdmi input content. Native apps work ok

@DarrellBowen87 

What is the spec of the HDMI cable(s) you are using? Are they HDMI 2.0 cables rated for 18Gbps?

[DarrellBowen87]

Im using the issued cable for my sky Q box. Also using the issued hdmi 2.1 cables for series x and ps5.

Is it happening on all ports? Have you tried switching the cables or the ports?
