I used another cable simply because I had one. Video Cables And AdaptersĪs for the video cable, it is rarely the culprit.

If a TV or another external monitor works with Mac mini, then the latter is not causing the issue. If you don’t have another device with HDMI output, you can use a device with HDMI input.įor instance, if your TV supports HDMI input, then try to use it as an external monitor for troubleshooting. You may or may not have the same things, so in case the approach could be slightly different. It took me less than 5 minutes to figure what the problem was, but I was lucky to have another computer with HDMI output (old MacBook Pro) and HDMI cable. Or sometimes, you could use F1 decrease brightness level and F2 to increase it. If the monitor has a digital menu, then use navigation buttons to get to the brightness section and verify the brightness and contrast levels. If you have brightness dials, turn it all the way up. It all depends on the type of display you have. Never I had one which was showing only system information, such as input information (analog/HDMI) and menu options.įinally, I decided to unplug the monitor from the power and wait 15 seconds before plugging it back.ĭisconnected power from the monitor was like a hard shutdown for your computer, while pushing the power button on display was a soft shutdown.īy the way, I forgot to mention that one of the first things you had to check is whether the brightness of the display was turned down to zero. Usually, they would be completely black or had some stripes of various colors. This let me eliminate the cable, and I could focus on the monitor. I swapped the cable, but the issue remained. My display was still black when plugged into the MacBook, so I could now eliminate the Mac mini as a culprit.Īt this moment, I was left with two probable suspects: monitor and cable.įortunately, I had another HDMI cable.

The same I saw when I connected the display to my laptop. In my case, when I tried to turn on and off the monitor by pressing the power button in front, I saw it blinking for a second and switching from analog to HDMI (my monitor has both VGA and HDMI inputs). In order to eliminate a problem with Mac mini, I decided to connect the external monitor to my MacBook Pro. In the case of Mac mini black screen, the issue could be with one of three main components: Mac mini itself, external monitor, and HDMI or USB-C cable (depending on the kind of monitor plugged into your computer). At this phase, you want to eliminate all unrelated causes for the problem. The first phase of any repair is troubleshooting. So, I decided to put a short guide while I am working on the problem.

Again, since I was too lazy and since I don’t really use Mac mini much, I left it in that state for several days.Īnd it would stay black screen of death unless my family bugged me for a couple of days to fix it. However, this drastic measure did not fix the issue on hand. In fact, I always suggest to avoid it if possible, but it’s Ok to do it sometimes. Since I was too lazy to fix it, all I did is to do a hard shutdown by holding a power button for several seconds. Last week the external monitor on my Mac mini 2012 went black.
