HDMi to dvi on new mac mini does not work

2 days ago , i recieved a Mac Mini M1.

HDMI to DVI did not work.

Called Support , told me to send M1 back. Monday I will get a new one.

Asked them , could it not be an overall problem. They laughed with me. On that time I had four people of support on the telephone, they all told me my M1 was defect. "Send it back" Now I read on the net that it is an overall problem. USB-c to DVI would work.

The support people did not know there job my believing. If I had bought my computer in the ALDI I could understand that they did not know, but for certified APPLE support people this is not done.

i try to get compensation I have to buy usb-c to dvi adapter.


I can not understand why apple did NOT test that ???????

Mac mini, macOS 10.15

Found a Solution.... The Star-tech powered 3 in 1 adapter worked! I was able to setup dual monitor DVI. one with a USB-C to DVI and one with the StarTech.com Travel A/V Adapter 3-in-1 HDMI to DisplayPort VGA or DVI - HDMI Adapter - 1920 x 1200 (HD2DPVGADVI). Since it is powered, it converts the signal. Powered the USB with a USB brick since I only get 2 on the Mac mini. Works great! Frustrating but now I get 2 monitors without using a USB video driver and don't have to replace my monitors and KVM.

There are a thousand different HDMI to DVI adapters out there, plus more than a hundred different old DVI monitors and it would be futile for Apple or anyone else to ever test all of them.


Beside DVI monitors are outdated tech. and you really would be better off connecting a newer HDMI Display or HDMI TV to the HDMI port.


While a USB-C to DVI adapter is likely to solve your problem. Sadly you may also find that not all USB-C to DVI adapters are created equal and they too may require some experimenting.


Ideally your best bet in the long run, is to replace that old DVI monitor with a newer HDMI, Display Port or USB-C equipped display.

Sorry, I did not mean to offend anyone by sharing a little bit of truth.


see > https://en.wikipedia.org/wiki/Digital_Visual_Interface DVI was designed April 1999; 21 years ago


In December 2010, IntelAMD, and several computer and display manufacturers announced they would stop supporting DVI-I, VGA and LVDS-technologies from 2013/2015, and instead speed up adoption of DisplayPort and HDMI. They also stated: "Legacy interfaces such as VGA, DVI and LVDS have not kept pace, and newer standards such as DisplayPort and HDMI clearly provide the best connectivity options moving forward.


Plus if you blink to long, you will also find that DisplayPort is been pushed aside for ThunderBolt 3/USB-C.


FWIW I personally have and maintain a half dozen earlier Mac Mini's. Most are running dual DVI monitors and so I totally understand and feel your pain. I also have/had big plans to upgrade one or 2 of them to the newer M1 Mac Mini, but now I waiting to see how this monitor issue plays out.


Sadly $200 will hardly make a down payment on the Displays that Apple lists under Accessories for the M1.

The link will give you approximately 50 DVI monitors that also have an HDMI input. Let me know and I'll send you my Venmo link.

That will not be necessary.

And next time you decide to apologize, make it sincere. The only way you would totally understand and feel our pain is if you actually owned an M1 and it didn't work as advertised.

Venting your frustration on me or other users, serves no real purpose. If you have a problem with Apple, then please feel free to contact Apple Support, send Product Feedback and/or return the M1 Mac Mini.


Have a nice day.

Just had an hour long conversation with Apple Support. A good conversation. Apple spent the time doing diagnostics. Because I have a 2014 Mac mini, we were able to screen share the two computers and run diagnostics on the M1 Mac mini while it was hooked into the DVI monitor.


So Apple is actively trying to resolve the problem. I go to the Genius Bar tomorrow and will send an update when I return. I don't know about everyone else, but having both usb-c ports available is preferable along with the HDMI to DVI being available for Apple Cinema Display users.

I think you are correct that HDCP is the reason HDMI to DVI adaptors that worked with older Mac mini's no longer work on our new machines. However, the USB-C to DVI adaptor *does* still work on my older monitor. My guess is that I could get an HDMI to VGA adaptor to run my second monitor (which would strip the HDCP), but after all of this, I've decided that it's time to just upgrade to a new UltraWide monitor anyway...

The new Apple adapter doesn’t work for me. Apple said that engineering is now working on the problem. I don’t know how high a priority this issue is other than Apple stating in the specs that DVI works.


went to the Genius Bar on Friday and they handed me a new M1 Mac Mini. I’ll plug it in tomorrow to the DVI monitor to see if it works.


I’m hoping the next update fixes it.

Apple is aware as I have a case open. Do they understand and has it gone to engineering yet? Unknown. Some posts here say it has been pushed to engineering, with no ETA for solution. Affect some or all monitors is unknown. Based on the number of posts here I am guessing it is a low incidence problem. Apple rarely addresses or solves low incidence problems. Thats just the unfortunate reality. The M1 mini is clearly spec’d to work using their DVI to HDMI adapter. Told me to order new one even tho I have an older version of that cable. Doubtful it will work.

Exactly. I too checked what the specs say and they say DVI via the HDMI DVI adapter. No ifs, no buts, no demand of HDCP support. I too contacted the support yesterday and the case was forwarded to the next level. I'm beginning to think that in stead of returning the Mini I may buy a USB-B DVI adapter for now, but never the less expect Apple to take care of this problem eventually.
