Last week we told you that a change in the latest YouTube app allowed better control over the resolution when streaming, and now two new (and requested) options have been added — 1080p and 480p streaming.
You'll need to have the latest YouTube app, and be watching a video uploaded in the supported resolutions, but changing things is simple. Start your video, tap the three-dot overflow menu in the upper right. On screen, you'll see a gear icon — tap it and choose your resolution.
These are server side options so you'll not need a new app, but they haven't rolled out to everyone just yet. Keep looking and let us know when you see more choices!
