Chromecast with Google TV HD picture jumping

[Brian181]

When using Chromecast with Google TV HD device, recently purchased from Argos,  I notice the picture momentarily freeze, or stall, or ‘hiccup’ frequently!  It renders the video stream uncomfortable to watch, although I am pleased with the resolution and general quality.  This happens with all apps (Netflix, Disney +, YouTube etc).  It is particularly evident with moving images obviously.  The audio / sound is uninterrupted.

For what it's worth, I get this with the NBA app - all other apps are fine. I hope someone has a fix, it's very frustrating.

Hi folks,

Thanks for posting here in the Google Nest Community.
 

Sorry to hear about the trouble. I wanted to follow up and see if I could be of any help. A few things: have you tried using the Chromecast on a different TV? Does it show the same behavior?

You can reboot your Chromecast and your WiFi router then observe if this will make any difference.

Let me know how it goes.

Thanks,

Juni

I haven’t managed to find any resolution, but here is what I tried and think I discovered along the way.  I wasn’t able to try a different TV, but did upgrade by router, thinking it might be WiFi related, this made no difference!  Watching lots of different films and YouTube uploads on different apps, I did notice that it wasn’t always apparent, so I do think it is related to the source content somehow, I think frame rate?  I did change a setting in my HD Chromecast, from auto to fixed 50Hz, and tried 60Hz, but it didn’t make any difference for me.  It was as though auto wasn’t doing anything for me, maybe the hardware was faulty?  

i have since taken my HD Chromecast back to the store for refund, because the picture freezing was unacceptable to me.

I intended to try a 4K Chromecast, even though my TV is only HD, thinking the processor in the 4K Version is better.  Based on technical advice in the store, I ended up buying a Roku 4K Stick.  Interestingly I had the same issue, again not on all content, not on all apps!  However, changing ‘Auto-adjust display refresh rate’ to ON from OFF did fix my issue (on Roku this option is under Settings / System / Advanced system settings / Advanced display settings).  Now, in reaction to each source that I play, the refresh rate is altered to match the source.  The video source does cause a brief black screen with the frequency advice to flash up, but this is no issue to me, as video playback no longer has the ‘stutter’ or freeze problem 🙂
