Q: EFI Firmware Update 1.7
I have 2.8 Ghz,16 gig Ram, Late 2014 Mini
My screen, on wake up from sleep, goes snow to black, snow to black, flash of color and then I get my normal screen. I have HDMI to HDMI. My Samsung monitor has a DVI and the HDMI connections, thunderbolts (2) on the Mini.
I read in support that a person there had better luck with Thunderbolt to DVI connection to the monitor.
I have the EFI Firmware update on my desktop but wonder first if that is not a repair or fix already accomplished for this computer. How do I discover the firmware I am using as the late 2012 required this firmware update. Does my machine require it to continue using HDMI or do I go to the thunderbolt DVI set up?
Mac mini (Late 2014), OS X Yosemite (10.10.2), 2.8 Ghz, 16 gigs RAM, one terra HD

The beginning of this article says how to determine the currently version of the EFI and SMC too
EFI and SMC firmware updates for Intel-based Macs - Apple Support
However, EFI 1.7 is for the late 2012 Mac Mini

I know of no firmware updates for the late 2014 Mac Min
Yes, Thunderbolt (Mini displayport) to DVI is better than HDMI
