4K on RPi 3

Hi everyone,

i have a question: is it possible to watch 4K videos on Libreelec (RPi 3)?

When I try to do it Libreelec crashes and I can't do anything. I tried to use xrandr via SSH, but it says:

sh: xrandr: not found

Thanks in advance

P.S.: Sorry for my English, but I'm Italian

Ok, thank you very much for the answer
