I have a UPSTAR 28 inch 4k UHD monitor, (http://www.kmart.com/upstar-28inch-4k-uhd-led-monitor/p-012W008507308001P). Now, what I want to know is, how does a 4k monitor have an option for 5K (5120x2880) in windows settings? Is this because I have gpu scaling and virtual super resolution turned on for my 8gb 580 in my radeon settings? I am very new to amd graphics cards, because my 1060 never had this option in windows display settings.
