Ubuntu 20.4; Samsung Monitor not seen

Good morning,
I installed Ubuntu Desktop 20.4 and it does not detect my Samsung S27D590 monitor. I am limited to a 640×480 resolution when I should have 1920×1080 (as in the past with previous Debian and Mint versions. using a HDMI direct connection. I suspect the issue is the Graphics Card,an older Nvidia GeForce 6150LE, and it’s specific linux driver is not available any more if, I am correct. Some machine info is here:
