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)

Hello xllluzionx,

Thank you for using Apple Support Communities.

It is my understanding that your MacBook Air is no longer connecting to external displays. I know how nice it is to be able to use more than one display with your Mac. The following article may be of some help to you:

Detect your display

If you're using an external display, sleep and wake your Mac to make it check for connected displays:

Press the power button on your computer to put it to sleep, or choose Apple menu > Sleep.

Wait a few moments, then press a key on your keyboard or click your mouse or trackpad to wake your Mac.

Cheers
