Whenever i set resolution of the screen to 4k (3840 * 2160), the refresh rate will be reduced to 30hz. The highest resolution that can ensure 60hz refresh rate is 2560*1440.
Can anyone confirm if this display card doesn't support 4k resolution?

The HD 7000 series supports DisplayPort 1.2 which allows for 3840x2160@60hz.
