Welcome to the land of high-definition diminishing returns, also known as.
Or at least that's one way of looking at the myriad new ultra-high-definition displays that all the big names and even some lesser-known companies are introducing this week at CES. In case you're out of the loop on what 4K is, it's a display standard that uses roughly 4,000 pixels horizontally across the screen; it has four times the number of pixels of 1080p and double that of a 13-inch MacBook Retina display.
If the hype around those now old-timey-seeming retina displays is true, then only a robot should be able to tell the difference between 2K (Retina-level resolution) and 4K. That begs the big question about all these bleeding-edge panels: why should we care?
Let us know in the poll just how much 4K has piqued your interest.
