But before you take a stance one way or another, let's consider what we already know about 4K resolution on TVs and current state-of-the-art resolution (2,560x1,440 pixels) on smartphones -- and the niche segment where 4K might actually make a real difference. 4K specifies a screen with four times the number of pixels as standard HDTV and phone screens, which have 1080p resolution. A pixel is a block of light that makes up the display's smallest unit of white or color. Think of a pixel as a brick in the wall that is the screen.
A 4K "wall" has 3,840 bricks along the top row, compared to 1,920 bricks for one row of a 1080p wall, and 4K also has twice as many rows, Despite all those extra bricks in a 4K wall, however, each one is so small that to most viewers with normal 20/20 vision at most normal viewing distances, they don't add up to a sharper-looking mural, Er, picture, Seen side by side, it's very difficult to tell a 4K TV spigen sgp neo hybrid iphone se case - satin silver from a 1080p one, 4K doesn't always live up to its promise of super-crisp resolution and crystal clear detail even on a really big TV, We've spent many hours over the last couple of years directly comparing 65-inch 4K TVs to their 65-inch 1080p counterparts, The TVs were compared from very close seating distances, between 7 and 8 feet away, That's quite a bit closer than most owners of big TVs sit, and on the brink of too close for comfort for many people..
Despite sitting so close to all the extra pixels in the 4K TV's panel, in most scenes we didn't notice any difference at all. What details did pop out were small improvements in close-ups (say, on a blade of grass or flower pollen caught on a bee's leg) from the very best, carefully curated footage used to demonstrate 4K's resolution advantage. The best example of 4K's resolution we've seen was on very big screens. Sitting about 9 feet from a 120-inch screen, we compared a 4K projector (also a Sony, for what it's worth) to a pair of units with 1080p resolution. In most movies we watched the differences were nonexistent, but in one we actually did see a bit of extra sharpness. So yes, with absolutely gigantic screens, 4K makes more sense.
We've scrutinized phones with 2K resolutions (2,560x1,440 spigen sgp neo hybrid iphone se case - satin silver pixels) like the 5.1-inch Samsung Galaxy S6, against other phones' 5-inch screens with lower, 1,920x1,080-pixel displays, Even comparing the same high-definition images with high contrast ranges on two phones, we often had to hunt for slight differences in sharpness and clarity between the two, and at a much closer range than most people view their phone -- mere inches away from the face, Even when we look very closely at a large-screen device like the 5.7-inch Samsung Galaxy Note 4 (which has a 2,560x1,440-pixel screen), it's almost impossible to see the phone's basic pixel structure at all, Put your nose (or better, a magnifying glass) up to any screen and you can usually see a grid formed of the spaces between the pixels, That structure is almost impossible to discern even from very close-up on today's state-of-the-art, non-4K phone screens..
With differences between sub-4K screens already so difficult to appreciate, it's hard to imagine what kind of benefit a 4K phone screen would bring to everyday phone use. A comparison of iPhone pixel density. When we're talking about screen resolutions and seeing pixel structure, what we're really talking about is how many pixels are crammed into every inch of screen. Or, going back to the analogy above, how many bricks make up a particular-sized wall. The more pixels you have per inch, the more detailed the image can become. We call this pixel density.
