I just got a new samsung monitor: S24E650DW and want to connect it to my imac. I had an mini-display to HDMI, and the store didn't have an mini-display to display port, so I thought I could use the hdmi-displayport.
The late 2015 imac running 10.12.6 however doesn't recognize that a external monitor i connected. In settings "displays" only show the build in retina display, and of course the samsung display show only a black screen, showing that it is set for display-port.
I have two mini-display to HDMI and tried both, so I think they should be working. Of course I tried both in both ports on the imac. The HDMI-display port-cable is brand new, and I don't have any way to test it, but I guess I must assume it works. I have tested the display on another computer at work, and it works fine.
I can't figure out what it is. that I don't understand. I read somewhere online that mini-display to display-port should work, I don't know if it is the HDMI junction that mess it up. Can anyone please help?
