I just checked and didnt saw the 60hz option available on the screen resolution page.

It happened to me too the first time I set it up. If you have a 4k screen and the correct hdmi cable try unplugging and plugging back and restarting the device. Then for me the automatic mode doesn't work and I have to select 4k2k60hz manually.
