Its Samsung Samsung U28E590D 4K monitor

Using Display Port 1.2.IF 4k or 3840x2160 is same thing then why 4k not supp 60hz on my UHD monitor?

That first setting looks like an imitation of some TV spec, use the lower "native" setting.

Go into your monitor's menu settings. Make sure you are on displayport 1.2, not 1.1

Seems like drivers. It is possible you have second resolution from another driver, that cannot go 4kx60 fps. I have no idea though if its monitor firmware or GPU (or maybe free-G sync?)

You do appear to have PC spec 3840x2160 x 60hz. "4k" can be different specs. Dedicated Movie / video editing monitors will be above that for DCI 4k (in it's various flavors). Your panel's PC native res is 3820x2160 x60hz 4k, and that is the spec you should select. I did have to ask about confirming 1.2 DP, since many older monitors default to 1.1.
