Is HDCP the issue?
I'm not yet set up for this. But researching on the web I found there are problems.
I was going to get Chromecast, and a bit confused whether a 4K mirroring (not 4K video) will display as 1080 or not.
On the Sony site, support says for mirroring to use miracast and doesn't mention anything else. It says 'WiFi certified miracast'. So now I am looking for a device that says it is wifi certified.
While on the XZ Premium itself, it mentions any type of mirroring, including chromecast. There is a thread on this forum about mirroring that refers to nothing but problems. I know that HDCP can cause a 1080 video source to only display as 480.
I did find something labelled as WiFi Certified Miracast, the Microsoft Wireless Display Adaptor which sells higher than the Chromecast Ultra and twice as much as the Chromecast.
To me the choice for a device is between Chromecast (standard) and the Microsoft Wireless Display Adaptor. Chromecast seems to have some superior aspects. Also it might be possible to connect to it directly without wifi that I have read, but I don't really know. But I am yet to know if HDCP is the issue.
And something about DLNA. I connected to my Sony bluray player using DLNA from the XZ Premium. For a wifi network I only have a portable device from Telstra, a Telstra Elite. On the bluray player, music and photos from the phone show, but there is nothing at all for video. Is that another clue to HDCP?
Update: I purchased a chromecast. I spent part of an afternoon trying to set it up. Setup information was incomplete. I know these things are apparently obvious but the pamphlet with it only said to turn on the chromecast and your device and go from there. I watched a youtube clip that seemed to do this too. You have to have a wifi on first, even though the chromecast mysteriously to me gets detected from the mobile device.
An added complication was that I was trying to set it up using phone data and have the one device as a hotspot. All research was confusing. As it turns out what actually happens is that the chromecast has a wifi to connect to given to it in the setup. This is impossible with the hotspot on the one device you are using. So puzzled I found I could actually use a laptop with Windows 7 (install the chrome browser) to set it up. Then I gave it the phone hotspot to connect to for wifi. Now that is used from the one phone that is used to cast and mirror with. A drawback is that under 'devices' you can't detect anything and it says to turn on wifi erroneously. So settings there can't be used. But who knows if they can be used on Windows 7, I haven't looked a lot yet.
After all this I tried mirroring with periscope and was disappointed to get audio lag. It didn't look that good for whatever reason. I came back and tried this again next day and all was much better, no audio lag, but it can get lag if it is left running for a long time though. It all looks okay to me. Chromecast, with no setings I can find, outputs in 1080p (never 24p) to the television. If there are audio lag issues, any bluray player gives you a control for that, but not on chromecast.
A concern was the message 'this device is not set up (optimised?) for mirroring'. Not entirely sure why I got that message, but all seems okay with normal use and that message isn't there. This was partly because I kept trying every angle to get the hotspot working.
One more thing, the mystery as to why a device that can't connect to its own hotspot works, probably is because guest mode is on, though I'm not entirely sure of anything. This might be switched off by default, so it needs to be switched on.
