Experts Say Human Eyes Can’t Handle This Many Pixels


If you give a human an HD screen, they’re
just going to want it more HD. But experts are saying we may have gone too far. A new report from NBC says you’re paying for
more than you’re seeing; that there are now so many pixels on some of today’s screens,
the human eye can’t even process how sharp the images are. http://www.youtube.com/watch?v=j9JKDzusKBM When it comes to televisions touting new 4K
technology, “a regular human isn’t going to see a difference,” said Raymond Soneira, head
of display-testing firm DisplayMate. http://www.nbcnews.com/technology/enough-pixels-already-tvs-tablets-phones-surpass-limits-human-vision-2D11691618 Well, maybe Superman should get a 4K TV. Those
TVs have about four times as many pixels as regular HD TVs. But a professor of ophthalmology
tells NBC the human eye has limits, and those pixels just won’t be perceived. Still, you might remember this LG commercial
that went viral earlier this year touting 4K technology. It made people not only believe
a TV screen was a window, but that they were seeing an explosion. (Via LG) http://www.youtube.com/watch?v=NeXMxuNNlE8 So, yes, it does look pretty real. But CNET reported in November that after “extensive
testing,” “Despite all the extra pixels I knew made up the 4K TV’s screen, most of the
time I didn’t see any difference at all.” http://reviews.cnet.com/8301-33199_7-57610862-221/four-4k-tv-facts-you-must-know/ Also, Digital Trends ran a piece earlier this
year called “How Many Pixels Are Too Many?” and pointed out the issue of eye strain. http://www.digitaltrends.com/computing/how-many-pixels-are-too-many/ Experts say pixels strobe, causing eye strain. http://www.advancedvisioncare.net/health_computer.htm There’s not really a lot of 4K content out
there yet for people to watch on those TVs, and they’re expensive — sometimes running
tens of thousands of dollars. Though some are available in just the low
thousands — Sony sells a 4K for $3,500. http://store.sony.com/xbr-series-4k-ultra-hd-tvs/cat-27-catid-All-XBR-Series-TVs;pgid=XXtYanialTdSRpwylrT2vmtw0000RthuAY_f;sid=yqnG6GzdNLyT6D5zIoJk7PTXpeWDmaXmhGwMGxUR Likely, 4K TVs will get less expensive, so
you won’t always be paying a ton extra for all those extra pixels. But it seems when
it comes to pixels, less is just about the same as more.
