Q: External Displays are no longer recognized

I am having an issue with my MacBook Air 11", 2013 Model where it will no longer connect to external displays.  When I plug in a Thunderbolt display adapter to the port on the right side of my machine, the laptop screen will briefly flash black but never recognize an external display.

 

I have tried the following configurations:

- Thunderbolt to DVI in Samsung External Display

- Thunderbolt adapter to HDMI in Dell External Display

- Thunderbolt to DisplayPort in Lenovo External monitor

 

All exhibit the same behavior.  I have tried to reset the SMC (although I do not get any screen feedback so I am not sure how I tell if it actually reset?), reinstalled the OS from recovery mode, behavior still exists.

 

Any help or tips/tricks would be great.

MacBook Air, OS X El Capitan (10.11.5)
