Quote:I'm pretty sure most of the top streaming sites have 4k content, like Amazon and Youtube.  Anything shot on film can be digitized to 4k, and any film shot digitally is either 2k or 4k, so most films can easily be offered by streaming sites at a higher resolution that 1080p.  The future of disc media is kind of sketchy, and the biggest hurdle for streaming 4k is bandwidth.  HD requires about 2-3 Mbps to stream, and 4k requires around 15-16 Mbps.  That's over 5x the bandwidth which maxes out a lot of people's internet speeds.  The other problem is that ISPs were already trying to throttle content at HD.
