HDMI 1.4 supports up to 144hz on 1080p. The Xbox Series X output is HDMI 2.1 (which is capable of 120hz at 4K) but is backwards compatible with 1.4. It depends on how the monitor was made. Sometimes it has to go down from 144hz to 120hz, or even 60hz because they didn’t build it for hdmi input (preferred display port). “Don’t answer if you don’t know”
