Hi,
I am receiving a 1920x1080 stream to display on my 1680x1050 monitor, but I would prefer to view the stream on my 1920x1080 TV instead. So I cast the image to my TV via my Chromecast, select "Optimise for full screen", and both image and sound are successfully transferred! Yay! However, my browser continues to display the image too, which causes the TV image to stutter in a not very watchable way.
I don't believe the full-screen optimisation I asked for has actually kicked in....
Could this be a bug in Chrome please? Or does the optimisation require some kind of TCP or UDP handshake that I must configure my system to allow for?
My Chromecast and my PC are on different network subnets, and I have already configured a multi-homed host for multi-casting and then connected these two subnets via a multi-cast repeater to get this far, not to mention tweaking a firewall to allow both IGMP and UDP/5353 traffic. So I'm fairly sure that neither "rebooting" nor "factory-resetting" anything is the answer here.
Thanks for any technical insight anyone can offer,
Cheers,
Chris

Actually, it seems that not cancelling "mirroring" during full-screen playback is Amazon Prime Video's fault, as other streaming services don't have this problem.
I've found this advice on the Web, but it appears to be out-of-date. Does anyone know of any other optimsations for casting Prime Video, please?
Thanks,
Chris

Hello chrisjr,
Thanks for reaching out to the Chromecast Community forum! Please try to clear the cache and data of the browser you're using and reinstall it. Rebooting the Chromecast and the PC might also help.
Also, if the issue is isolated when using the Amazon Prime Video, please reach out to the app developer for further help.
Thanks,
Jennifer

Hi Jennifer,
Thanks for replying. I have confirmed that the full-screen optimisation works correctly for both YouTube and BBC iPlayer, and the only affected site at the moment is Amazon Prime Video, so this does appear to be more of a case of Amazon providing lack-lustre Chromecast support than anything else.
It would be useful if Chrome had an explicit option to disable mirroring, rather than having it as an optimisation for full-screen mode.

Seriously, no. Getting this far has required me to bridge MDNS across two subnets separated by a firewall, and then install WidevineCdm successfully into my installation of Chromium. So I can categorically state that rebooting my devices is not the answer here.
Could you try rebooting your devices please, on the off-chance it might help? 🤔
Thanks,
Chris

Hi there,
Got it. If the issue is isolated with Amazon Prime, it will be best to reach out to the app developer for additional help. Also, for the option to disable mirroring, rather than having it as an optimization for full screen mode, I'd suggest you send feedback about this using the Google Home app. Every bit of feedback helps a ton. Here's how.
Thanks,
Jennifer

Jennifer,
The first bit of feedback I'd like to share is "How can I share feedback when I cannot run "Google Home"?
My phone runs Android 7, whereas Google Home requires Android 8. And Google no longer supports running apps from within Chrome either 🙄. I had to borrow someone else's phone to configure my Chromecast in the first place, and then invite myself to my own Home from there. Not that I've been able to accept the invitation yet, mind you.
Fortunately, I only need my Chromecast to cast streams from my browser to my TV.
But if I wanted to live in a "walled garden" then I'd use Apple devices 😑.
Cheers,
Chris

Hey chrisjr,
I understand. If you can still update your phone's OS, you may try that so it will be compatible for the Google Home app, but I appreciate your effort in going the extra mile just to send feedback about this. Feel free to let me know if you have other questions and concerns.
Best,
Jennifer
