It seems pretty weird to me that there is even a distinction between videos that you send to the tv to play and videos you select on the tv directly (like way less options, different UI)
It somehow seems that the quality is worse as well when casting from the YouTube Android Phone App, or is it just me?
========================================
Edit: it has been confirmed that it is lower quality, especially 4k Videos are only played in 1080p
u/yothisisyo suggested a great way to fix this:
Just go to the tv app and in the settings open the "link within code" tab Then type that code into the YouTube phone app and the videos will be played using the superior player (with queue and all that stuff)
Ye casting only up to 1080 i think no 4k support
