1080p HD Is Coming to YouTube 
We're excited to say that support for watching 1080p HD videos
 in full resolution is on its way. Starting next week, YouTube's
 HD mode will add support for viewing videos in 720p or 1080p,
depending on the resolution of the original source, up from our
maximum output of 720p today.
As resolution of consumer cameras increases, we want to make 
sure YouTube is the best home on the web to showcase your content.
For viewers with big monitors and a fast computer, try switching 
to 1080p to get the most out of the fullscreen experience.

Not even justice， I want to get truth.
