After upgrading to Ubuntu 18.04, display is like zoomed

Solution 1:

I had the same problem, but figure it out that Zoom was active. Just go to Universal Access in Settings and disable Zoom.

Hope it helps.

Solution 2:

I have nvidia GeoForce GTX 1080 graphics card.

I went to Software & Updates and then to the Additional Drivers tab and selected what is given in the below image. It installed the drivers after which I rebooted and it was fine.
