I'm using ubuntu 20

checked hdmi cable which is working fine

I'm running out of ideas how to get rid of this line.

Does this monitor have to be replaced? Bought it January, this year.

I recommend letting a service technician have a look. Send your full model code and serial number via private message to get started.
