This new desktop design highlights your favourite videos and creators while making YouTube easier and more fun to use. We're still working on it, but we can't wait for you to try it out and let us know what you think!
And if playing 4K videos at 3840x2160 isn't enough to melt your device, try doing it at 60 frames per second. We've combined these two cutting-edge features for a few videos in this playlist. This feature may not work well on every device, but if you've got some powerful kit at your disposal, try it out!
