Intel previously said that Broadwell notebooks should enjoy about 90 extra minutes of battery life compared to a similar 4th-gen Haswell Core chip, with 22-percent faster integrated graphics and 50-percent faster video conversion—although it's not quite clear whether that was supposed to come about before the driver release, or after it.
The other potential 4K colour benefit is that the arrival of the format has got the AV world thinking about other aspects of picture quality too, leading to discussions of new video standards that support wider colour ranges.
Standard definition began life as NTSC TV broadcasts before switching to digital with the introduction of ATSC in 2007. When George Lucas was preparing to make his long-promised prequels to the "Star Wars" movies in the late '90s, he was experimenting with new digital formats as a replacement for film. If movie houses could simply download a digital movie file and display it on a digital projector , the industry could save a lot of money. It would take one of director Ridley Scott's contemporaries to truly drive 4K into your local cineplex.
More interesting than an entry-level TV, however, is Sharp's attempt to stand out from the many other manufacturers out there pushing 4K: the new Sharp "Beyond 4K Ultra HD" TV. It's a massive 80-inch panel with impossibly thin bezels, but that's not what the company is counting on to help it stand out from the crowd.
