HDMI cinema display doesn't work

Hello all,

I'm trying to get a 23" Cinema display miniDP to work on my HDMI port as a second monitor. I have two Cinema displays, the HDMI refuses to work. The thunderbolt works with either monitor, HDMI neither. Previous to this I was using two 22" Acer monitors with no problems (apple DVI to HDMI). Since the monitor uses a miniDP I am using a new adapter to HDMI. Assuming my adapter is good, is there a way to get the HDMI to recognize the Cinema display? I have reset PRAM. Detect display is a no-go too.

Mac mini, OS X El Capitan (10.11), 16 GB ram, 250 SSD

How are you connecting the mini displayport input on the monitor to the HDMI output on the Mini?

Some adopters like the mini displayport>HDMI adopter like the one in your link do not work in reverse.

You need an adopter like:

So, there's more to it than connecting a-b-c.

Frequently stacking adopters does not work. The one adopter you linked to said mini displayport-to-HDMI, not HDMI-to-mini displayport

Any reason the one you linked to wouldn't work for a 23" display and a mini?
