[QUOTE="kitjv26, post: 1831988, member: 396869"] I will try the VGA input on the NEC. I will have to get a cable first. I do have a backup external drive which I tried using as my startup drive since Mojave is still mounted as the OS. I was surprised that the screen on my NEC display continued to be black. I rebooted both the NEC & the iMac to no avail. [/QUOTE]
