Recently I purchased Plugable USB 3.0 HDMI / DVI Adapter and connected to my thunderbold port (reason why I bought this adapter is because I already have external ssd drive connected to thunderbolt)
Now… I tried to turn off mirror display so I could get as much resolution on the external screen, but even when I close lid of the laptop, both screen remain active (external and laptop’s) this causes effect of two screens, I tried to “move around” screens in the Display setting but to no avail,
Is there a problem with the adapter/driver or maybe something (hopefully) else is needed
If I have mirror display on, I get high resolution but not maximizing external display…
thanks in advance for any help!
