Micro DisplayPort HDMI adapter not working

Hi all,

I thought I already had an account here, but obviously not … Anyway!

I bought an HDMI adapter - Micro displayport and, I see that it does not work! My secondary screen is not even detected! (Unlike single HDMI cable)

I then wanted to know, if there were any drivers to install or, I don’t know what others?

Thanks for the help !

Please excuse the question.
Just to make sure.
Does your adapter perhaps need additional power supply (via separate USB connector)?

No, at all, that’s right, I plug my HDMI cable into the adapter and, I plug everything in micro Displayport to the PC

It’s explained here.

Ok, nice !
