Hi all,

This is my first post on this site (found it and signed up yesterday), I have a question about screen mirroring from android to a Sony TV. I used to have a VDSL broadband with Vodafone and when watching YouTube videos on my Sony TV I could never understand why the quality was quite poor even on the HD videos, after some research I found it was probably the TV adjusting the quality itself to match the WiFi speed, and there was no manual override to change the quality setting (which would have just caused buffering anyway I guess).

I have just had Vodafone fibre x installed however and I am getting much faster WiFi speeds, and I have also not connected the TV to the new WiFi but have instead ran an CAT6 Ethernet cable from the modem to the TV. I have been able to use the screen mirroring function on the youtube app on my phone to select the videos to be played on the TV and the quality is great, my question is though however when I do this how are all three devices connected? as the TV is not connected to the WiFi (I think because I have not put the new WiFi password in) does this mean that when I select a video on my phone, it loads on my phone using the WiFi and the TV loads the same data using the Ethernet cable?

Or is there something else going on here I may not know about?

Thanks,
