M1 mini and iMac 2010 target display (mini DP) or 2 23" DVI cinema displays

[MvdM]

I have plans for buying an M1 mac mini.
My current late 2012 mini is connected to two 23" cinema displays. One via an HDMI to DVI adapter and one via a thunderbolt to DVI adapter.
Does the HDMI to DVI adapter plus a new to buy USB-c to DVI adapter work with the M1 mini?

I also have an iMac 2010 that can be used as a target display.
What is the best way to connect an M1 mini to this display? HDMI to mini dp or USB-c to mini dp? Does it even work?

Right now I don't want to buy a new display.

Just found out (the hard way) that M1 Macs do not support target display...

There has been evidence that the older Apple Cinema Displays do not work with adapters on the new M1s (when the same setup works on non-M1 Macs. So I would consider it incompatible until someone specifically shows you one that is working. You would need to use the exact same make/brand adapter that they are using to the T if they say that it does work.

More complaints than celebrations thus far... as in, I found no confirmed celebrations.

There's a fairly long thread here (somewhere) discussing the problems of using DVI Cinema Displays with an HDMI adapter on the 2018 Mini, IIRC it has something to do with the voltage provided by the Mini's HDMI port. Evidently people have better luck with a DVI to MiniDisplayport to USB-C adapter. I still have the 23" Cinema Display that I bought around 2006 and was using it up until I got my 2018 Mini in June when I decided it was time for a new monitor.

Sorry, don't know how this translates to the M1 Mini, but I wouldn't be surprised if you had problems.

I also found out that my 2013 iMac (target display mode), 27" Apple display (Thunderbolt 1) and 24" Cinema LED display (mini DP) will not work with the M1.

I usee the Apple TB3-TB2 adapter dongle on all 3 displays.

Someone said that there is no longer any Thunderbolt negotiation on the new M1.

Bummer for me because I really wanted to use an Apple display as I have done traditionally over the years.

I really hope a 3rd party manufacturer will come out with a M1 to Mini Display, Thunderbolt 1/2, and eSATA adapter....

You can connect a 27" Apple Cinema Display (Thunderbolt model) to the new M1 using the Apple Thunder Bolt 2 to Thunderbolt-3 Adapter. Confirmed in the thread below. Scroll down to ratephi's post.

Target Display Mode doesn't work for any Mac anymore... stopped a few OSes back.

There are no confirmed success stories with the Mini DisplayPort version of the Apple Cinema Displays unfortunately.

Did you find a way around this at all? I have just bought a M1 MM to use with my mid 2011 iMac 27" and am a little worried that its the MM that won't play ball!!

I don't have an M1 Mini, but evidently they will not work with target display mode on the iMac - see this:

Mac Mini With iMac as Monitor

My 2011 Imac 21.5 is getting a bit old and tired and has reached the end of the OSX upgrade path at High Sierra. I'm considering a Mac Mini and using the old iMac as a monitor. Is this a completely crazy idea? BTW the iMac has an 2.5GHz Core I5, 16 GB memory and a 250GB SSD. Would a better...

Thanks for that, I read through a number of posts and threads including this one, this is the only one I found where the M1 was the cause for failure, all others seemed to fail because of wrong iMac or wrong macOS or wrong cables.
