Your display may not support 60Hz. Your display might require a firmware update to support 60Hz operation. Contact the maker of your display for details.

Many early 4K displays use Multi-Stream Transport (MST) to achieve 4k @ 60Hz. Follow these steps to use the display's built-in controls to enable this feature:
Sharp PN-K321: Choose Menu > Setup > DisplayPort STREAM > MST > SET
ASUS PQ321Q: Choose OSD menu > Setup > DisplayPort Stream
Dell UP2414Q and UP3214Q: Choose Menu > Display Setting > DisplayPort 1.2 > Enable
Panasonic TC-L65WT600: Choose Menu > Display Port Settings > Stream Setting > Auto
Other DisplayPort displays: check with the display manufacturer for compatibility information.

Make sure the HDMI cable you are using is a Premium High-Speed HDMI Cable certified by

If you are trying to connect at 4k@60Hz via HDMI 2.0, you may have to set the color depth to 8-bit at 4:4:4, 10-bit at 4:2:2, or 12-bit at 4:2:0, or you may exceed the HDMI 2.0 bandwidth. A few 4K TVs (2017 Element Fire TV and 2017 LeEco Super 4, for example) don't support 4K@60Hz@4:4:4 at all.

For connecting to a 4K TV, you may need make a custom color resolution. Set resolution to 3840x2160 at 60Hz and set Timing standard to CVT-RB (reduced blanking). Some TVs require you to turn on "UHD Color" or "Advanced" or "Enhanced" setting manually in the picture settings for the HDMI port.
