There is a feel. Our job is not to make you feel like you are watching a newscast or something live. We want you to loose yourself for two hours. You get more out of a film projected than out of a video projected. The films that Disney and the films that Pixar have done for the past 12 years have all been rendered at resolutions of 2K and below.
Quality is a lot of different measures.
It's not just about how many pixels. It's about color depth, accuracy of reproduction, stability of the image and repeatability from performance to performance. But overall, networks capable of handling the astronomical amounts of data that 4K or higher would require don't really exist. And Hummel raised concerns about network reliability. You get people in the server arena that find server failures and hard disk failures acceptable to a certain degree.
