display refresh rate

Hi there

I have my 2021 mbp hooked up via HDMI to an LG 55EG910V

The refresh rate is spec'd at 100 / 120

as can be seen here

I'm using HDMI direct but the os x display prefs only let me go up to 60hz

Is this a bad cable?

Whats the fix?

thanks


MacBook Pro 14″, macOS 12.2
