Primary monitor showing as UNKNOWN and refresh rate is off

[Marcel Franke]

Hi, I'm also facing the same issue in version 24.04 that wasn't present in version 22.04. Since upgrading, my monitor is identified as 'unknown,' and I'm unable to adjust the refresh rate from 60Hz to either 120Hz or 240Hz, even though my monitor fully supports this Hz level.
