I'm hoping that someone here has some technical insights. I purchased a used Late 2014, 2.6 GHz, i5 (not a bad little machine...so far). When I got the machine, first thing I did was install an M.2 to accompany the 1GB drive that was already in it.
So when I turned it on and was trying to boot to the boot selector, I had no screen (was using the HDMI port). I switched over to the DP (mini-dp to DP) and got it moving and installing. After that I migrated everything from my other machine.
Now that I have everything up and running I am trying to diagnose the HDMI issue. First thing I did was contact the seller (off eB) and asked him about it. He advised HDMI was how it reset and tested the system so I have to believe it worked at some point prior to coming to me.
Are there any other tests or something I can look at to help diagnose? On a whim, I did reset the NVRAM and even though some other suggestions were to go into display settings and hold the option key down to get to 'Detect settings' (tried changing to 'scaled' as well), nothing I do will get me to that...it just never appears...and yes, I have tried different cables!
I'm trying to go down this route before I go out and purchase a USB to DP adapter or some sort of dp/thunderbolt dock.
Would be so much simpler if one could just use both dp ports!
Just FYI, both of my monitors are Dell U2412M's and worked flawlessly on my previous Mac (the one I migrated from) and both machines are running Monterey.
