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?
This was a big one for me, for the longest time I could not figure out why I couldn’t get YouTube to play videos over 1080p for me in Firefox on my PC, it ended up being some weird setting that I changed in
about:config
(I sadly cannot recall which one) a long time ago - but I’d always copied my Firefox profile with me so that bad setting stuck around.
