I am running OS X High Sierra (10.13.6) and using a Targus DOCK110. I am able to connect to a monitor with a VGA connection great but when I try to hook another monitor it mirrors the first monitor. I am using it on a MacBook Air.

How can I have the second monitor not mirror the first one?

When I go to System Preferences | Displays | Arrangement it only sees one of the two external monitors.

Thank you for looking.
