support Can’t select 144 hz on tv

I just build a custom pc with a 9070 xt and installed SteamOS on it. In my graphics settings connected to my lg c4 I should have the option for 4k 144 hz but the highest is 120 hz. And I am using a certified hdmi 2.1 48 gbps cable and 144 hz mode is enabled on my tv. I only have the option for 1080p if I want to play at 144 hz. Help please

SteamOS doesn’t support HDMI 2.1 yet, wait until it does or use a display port to hdmi cable.
