I have a Mac Mini (late 2014) which doesn't see the external display (attached via HDMI). There is a "detect displays" button on the Display Preferences pane which in later versions of Mac OS X became hidden, but can be revealed with the Option key. Hower, on this particular Mac nothing happens when I press the Option key (but it works fine on all my other Macs). I am running l Capitan. Any thoughts ?

Try resetting the SMC

You are using the same cable that work with the other Macs, right?
With only this monitor connected do you see a boot screen?
If not then make an appointment at the Genius Bar of an Apple store since it appears you have a hardware problem.

I have just tried resetting both SMC and PRAM, no difference.
No, I don't see a boot screen.
I will take it to the Genius Bar but I'm a little bit sceptical that it's hardware as I would have thought a button not appearing is more like software.
Incidentally I have 4 Mac Minis (all 2014) and I have seen similar problems on all of them, the screen not working after booting up, but usually after a bit of fiddling around it works. It just seems a very temperamental device in this area.
I have had a 2009 and 2012 Mini and have never had such problems.
Mine is a bigger sample 🙂 However, I agree, I have had about 8 Mac Minis prior to the 2014 models and I also never had such problems.
