My family quite recently bought a 4k Lg tv (65uf860v) that I believe does 60fps. Its using webos 2.0 so I don't know if that's the problem, but I can't for the love of God get the Youtube app to play 60fps in youtube 60fps videos. It works perfect on my iphone. The tv does 4k videos on youtube but only max 30fps. I have checked on the video info on youtube videos. Can someone please confirm if the app is capable of 60fps or if it is my tv that wont handle that frame rate on youtube.
