Mac mini video output problem

The seller, dvicetech, immediately suggested shipping me out a replacement DisplayPort-DVI adapter, at his own expense. This really pleased me, since combined with dvicetech taking on this extra cost, it seemed like a very reasonable next step to try — hopefully the problem would turn out to be with the adapter, not the Mac Mini itself. To my shock, this worked! I contacted dvicetech with this news. At this point, dvicetech wowed me further with his great service by shipping out not one but two additional display adapters to try: The Mac Mini booted up and worked just fine at that point.

So I put sent the three remaining, unused display display adapters back to dvicetech using the envelope that he had provided. I was seriously blown away by the customer service dvicetech provided — excellent, prompt, polite communication; smart troubleshooting suggestions; and multiple packages shipped back and forth at his own expense — which I daresay beat out even what I would have gotten from Apple directly, had I purchased a new Mac Mini.

My advice is when shopping for parts on eBay, buy from dvicetech if possible — I certainly intend to do so in the future! When I use some more specific Google search terms like mac mini viewsonic no video , there are lots of other similar problem reports. My takeaways are:.

Well, my Mac Mini Late is having some troubles with the HDMI after macOS High Sierra, not exactly the same as you, but specially after sleep the size of the display is wrong, the dock and the finder are almost out of view, I need to unplug and replug the HDMI cable to fix the issue, more than annoying to be honest.

Nov 11, 3: Upgraded to Hi Sierra now have no video and regret doing so. How do I return to previous version? Is that even possible? Nov 12, Sorry for that.

No video output, however appears to be booting up?

As written previously, I have a bug report with Apple. So even if you boot on the Startup Manager, there is no video. So it looks like the issue is more closed to a Firmware issue than to an OS issue. I hope that Apple will find a solution. Best regards. Nov 12, 7: Thank You for the info. I discovered my display did indeed come up after unplugging the HDMI and plugging back in. It took roughly 5 or so min. Surprise, now to keep it up until Apple gets its s Petralyn If you restart the Mac mini on the Startup Manager "alt" at startup , do you have the video display immediately or after some minutes?

The screen turns black when the autologin takes place. There is a white line of a few pixels high and about 1 cm wide in the upper left corner.

I changed the battery settings for my Mac Mini to never go in sleep mode and I left the Display sleep at 10 minutes. I noticed that the black screen is caused by the wake up from the display sleep. I removed autologin to be sent to the login page first after a reboot. Nothing is going to fix this. I've reinstalled it three times. Same results. What's needed is a fix from Apple!
