3.840 x 2.160 and 60Hz ?

hello together I bought the new NUC 8i5BEK2 and the new Libreelecversion Leia V.8.90.006 on the NUC. Since I have a 4K TV, I put the ad on 3.840 x 2.160. Unfortunately, the menu gives here only 30Hz as picture frequency. The new NUC can actually do this resolution! The selection menu is also no 60Hz. How can I say Libreelec please go with 60 Hz on the way?

Thank you all

Frank

My TV is the sony KD-55X9305C.

Have just read 4k with the resolution 60Hz is only in the Comuterformat: YCbCr 4: 2: 0/8 bit!

Can I stop this in Libreelec?
