If my monitor has no MacOS driver available, do I have any other options for adjusting overscan? | macbook 2017 I have a 2017 13" MacBook Pro -- I just setup my monitors, connected via two usb-c to hdmi dongles. One of my monitors works fine (ViewSonic VS2450), but the other extends the desktop beyond the edges of the monitor (HP 2509m).

I checked the HP site for my monitor, and there are only Windows drivers available. I didn't have to install any drivers for the ViewSonic monitor to work.

Do I have any other options to correct the overscan?
On the 2509m there is a button that says "Auto" and immediately underneath it says "OK".  When you press this button the display will throw up a text boxy that says "Auto-Adjustment in Progress" and that should correct your overscan issue.  I just discovered that by accident. :)
