Can only select 4k@24hz on N2

Shouldnt I be able to set it to 4k@60Hz or is there some limitation?
I run a through a Sony HT-ST5000 soundbar to my https://www.panasonic.com/dk/consumer/smart-tv/4k-pro/tx-75fx780e.html

Just wondering if it could be bad cables or someting else or if there is just a limit in CoreElec to 24hz

Page 19 of the soundbar manual make sure the HDMI ports are set to enhanced mode.

Thanks I forgot about that, also when I changed it, it didnt work, but thats because I had selected 4096x2160p instead of 3840x2160p, now I am running 60Hz happy days!
