Uhm... 'Dell introduces "5K" 4K monitor' !? Either it's 4K or it's 5K... And this is 5K. Or 5.12K to be exact. The "K" (1000) is the amount of pixels horizontaly/longest side.<br>FYI: A 4K 16:9 display is in reality "just" 3.84K and a Full HD 16:9 is 1,92K. But we still call them 4K and 2K/FHD since it's easier.
