Too low to display

Now that there are 4K TVs everywhere, it would take a concerted effort from at least one big TV manufacturer to right the ship and abandon use of 4K in favor of UHD and 2160p. In all honesty, though, it’s too late. That said, the more important problem isn’t really the name; it’s where in the heck we can all get some real 4K content to watch. So far, it’s appearing in dribs and drabs on services like Netflix, Amazon Instant Video, and some proprietary hardware and software products from Sony. That’s not yet enough for 4K to really take off.

To make matters more confusing, UHD is actually split in two — there’s 3,840 by 2,160, and then there’s a big step up, to 7,680 by 4,320, which is also called UHD.
