Just bought a 4K panel? Well guess what, it's obsolete already.
Yes, Dell's new UP2715K packs in an astounding 5120x2880 pixels into a 27-inch Crystal Clear panel. That's roughly 14.7 megapixels, versus the measly 8.3 megapixels of your 4K panel. Yes, 70 percent more pixels. Can you even run this over DisplayPort? Of course not. To push this many pixels, you need to use not one, but two DisplayPort 1.2 ports. For this demo, Dell had the monitor running off of a Quadro K5000 card.
