Issue with MX450 and nvidia-driver-450 - Ubuntu 20.04


For some reason, laptop screen is named as Unknown display when I go to the display settings.
When I plug an external screen using the HDMI port, it is not detected at all.

Any idea, on what’s going on ?

Are there some limitations for the MX450 when using Ubuntu ?

Thanks for your help
