I use Youtube on deck in Firefox with youtube.com/tv in kiosk mode. Works really well, but I noticed even when I have a bigger screen connected I can only watch videos in up to 720p. It doesn’t let me select anything higher. Is that a YTTV thing or is there a problem in my setup?
i use Freetube on my deck which you can set the default video resolution to 1080. works well in gamemode.
