Google ‘won’t fix’ UK-based Chromecast judder



Google has revealed it has no plans to resolve a ‘judder’ issue with its Chromecast streaming stick.

The budget streamer has seen a wave of bug reports over dodgy video playback in the UK and Europe.

It turns out that the Chromecast is set up to shoot video across HDMI at a 60Hz refresh rate – the American standard.

Unfortunately the European standard for refresh rates is 50Hz – that’s the number of times a signal passes the zero point in a single minute.

The problem herein lies – most European video content ships at 25 or 50 frames per second, neither of which sit pretty in a division with Chromecast’s 60Hz refresh rate.

This means that there’s a slight mismatch in frame display because Chromecast has to leave some frames on the screen slightly longer to achieve proper sync.

The same thing happens when you view 24 frames per second cinema footage on a 50Hz or 60Hz TV – they both judder, although 60Hz moreso due to the greater mismatch.

Google has decided to tag up the problem – dubbed Issue 374 – as ‘WontFix’, although it does acknowledge that it is a ‘defect’ and set its priority to ‘medium’.

Google’s actual response? “Chromecast cannot attempt to handle changes in HDMI refresh rates since it is very hard to accurately identify the incoming frame rate,” read the post.

It continued: “Also, every time there is a HDMI mode change, it usually leads to flashing or loss of picture for a few seconds.”

This led to further anger because other media streamers have the ability to change frame rate depending on refresh rate, confusing many over why Google wouldn’t offer the same software fix.

Strange, I use my Chromecast A LOT for streaming BT Sport to the TV and that works flawlessly.. (2013 Sony Bravia, BT Sport app cast from an Android tablet)

This aftects most of the streamers. My Roku 3 has the same issue. 50Hz content down to a TV that is 50Hz and it stutters like mad. 60Hz content down to my UK TV and it is fine. Haven't found a way around this yet....

I live near Stockholm. Bought one Chromecast. It was crap and brought it back. I bought another thinking I may have screwed something up with my first one. Brought it back. It was a piece of crap.

Seriously, I thought with digital tv, refresh rate issues were a thing of the past.
