Audi uploaded an Ultra HD video to their USA YouTube channel for the Audi A3 family. The Ultra HD format is the next step of the digital broadcasting and will turn your Full HD TVs into a rubbish. This new format’s resolution is 3840×2140 and you have chance to see the details more accurately than the existing HD technology. But your iPhone cannot record Ultra HD yet!
If you wish to watch an Ultra HD video, here it is from Audi.
