Mini displayport issue connecting to external Display

Hi guys,

I'm having trouble connecting my 2012 MacbookPro to any external display.

I used 2 setups, both involving my Mini displayport. First setup is Mini displayport - Philips Display1 connected by HDMI adapter. The 2nd setup is Mini displayport - HP Display2 connected by VGA adapter.

None of them work, the external displays just do not show anything. My OS is Sierra. I also need to mention that my Mac is working flawlessly.

Does anyone have an idea about what the issue may be? It is really upsetting since i really need an external display for my work.

Thank you!

I forget to mention that try to run Apple Diagnostics if it reports Thunderbolt related issue in the case it's caused by hardware trouble(NDT001 to NDT006).

thanks for the tip. i've run the diagnostic, luckily there's no hardware bug.

i am using simple mini display port, not Thunderbolt. i know it's the same physical port, but i don't have a Thunderbolt adapter. still searching for a clue :(

Hi,

I'm using external display with Thunderbolt(mini display) port to DVI adapter which works well.

My MacBook Pro is Retina 13inch late 2013.
