Question Lost the 120hz option on my TV

[Ed.Mush]

Well, i have a Samsung Q60 55'' with the option of 120hz. My old PC setup, i was able to get 120hz on 1080p AND 1440p, but now with a totally new setup, i just lost the option at 1440p. It only shows me 60hz while in 1080p i can still set to 120hz.
I'm using an HDMI cable, nothing changed and i don't know why... I bought this TV because of the 120hz to play 1440p, i don't care about 1080p because my main monitor is 144hz already... Any advice on what to do now?
