Which best settings on this TV for Series X. 4:2:2 On\off? Standard\RGB mode? 4k:120hz or 4k:60hz? Seems quality better in 4k:60hz Also: 4k:120hz:PCrgb is ok. 100% native supports of 4k:120hz or application on this TV? Game process to low\smooth in 4k:120hz, in 1440:120hz game play seems native and better, but no resolution.
